Components

Accordion Group

ionChange is no longer emitted when the value of ion-accordion-group is modified externally. ionChange is only emitted from user committed changes, such as clicking or tapping the accordion header.
Accordion Group no longer automatically adjusts the value property when passed an array and multiple="false". Developers should update their apps to ensure they are using the API correctly.

Action Sheet

Action Sheet is updated to align with the design specification.

Design tokens

Token	Previous Value	New Value
`--height`	`100%`	`auto`

Button

Button is updated to align with the design specification for iOS.

Design tokens

Token	Previous Value	New Value
`$button-ios-letter-spacing`	`-0.03em`	`0`
`$button-ios-clear-letter-spacing`	`0`	Removed
`$button-ios-height`	`2.8em`	`3.1em`
`$button-ios-border-radius`	`10px`	`14px`
`$button-ios-large-height`	`2.8em`	`3.1em`
`$button-ios-large-border-radius`	`12px`	`16px`

Back Button

Back Button is updated to align with the design specification for iOS.

Design tokens

Token	Previous Value	New Value
`--icon-margin-end`	`-5px`	`1px`
`--icon-font-size`	`1.85em`	`1.6em`

Card Header

The card header has ben changed to a flex container with direction set to column (top to bottom). In ios mode the direction is set to column-reverse which results in the subtitle displaying on top of the title.

Checkbox

ionChange is no longer emitted when the checked property of ion-checkbox is modified externally. ionChange is only emitted from user committed changes, such as clicking or tapping the checkbox.
The --background and --background-checked CSS variables have been renamed to --checkbox-background and --checkbox-background-checked respectively.

Datetime

ionChange is no longer emitted when the value property of ion-datetime is modified externally. ionChange is only emitted from user committed changes, such as clicking or tapping a date.
Datetime no longer automatically adjusts the value property when passed an array and multiple="false". Developers should update their apps to ensure they are using the API correctly.
Datetime no longer incorrectly reports the time zone when value is updated. Datetime does not manage time zones, so any time zone information provided is ignored.
Passing the empty string to the value property will now error as it is not a valid ISO-8601 value.
The haptics when swiping the wheel picker are now enabled only on iOS.

Input

ionChange is no longer emitted when the value of ion-input is modified externally. ionChange is only emitted from user committed changes, such as typing in the input and the input losing focus, clicking the clear action within the input, or pressing the "Enter" key.
- If your application requires immediate feedback based on the user typing actively in the input, consider migrating your event listeners to using ionInput instead.
The debounce property has been updated to control the timing in milliseconds to delay the event emission of the ionInput event after each keystroke. Previously it would delay the event emission of ionChange.
The debounce property's default value has changed from 0 to undefined. If debounce is undefined, the ionInput event will fire immediately.
The detail payload for the ionInput event now contains an object with the current value as well as the native event that triggered ionInput.

Design tokens

Token	Previous Value	New Value
`--placeholder-opacity`	`0.5`	`0.6`

Item

Design tokens

iOS:

Token	Previous Value	New Value
`$item-ios-font-size`	`17px`	`16px`
`--inner-padding-end`	`10px`	`16px`
`--padding-start`	`20px`	`16px`

The swipeToClose property has been removed in favor of canDismiss.
The canDismiss property now defaults to true and can no longer be set to undefined.

Overlays

Ionic now listens on the keydown event instead of the keyup event when determining when to dismiss overlays via the "Escape" key. Any applications that were listening on keyup to suppress this behavior should listen on keydown instead.

Picker

The refresh key has been removed from the PickerColumn interface. Developers should use the columns property to refresh the ion-picker view.

Radio Group

ionChange is no longer emitted when the value of ion-radio-group is modified externally. ionChange is only emitted from user committed changes, such as clicking or tapping an ion-radio in the group.

Range

Range is updated to align with the design specification for supported modes.

Design tokens

iOS:

Token	Previous Value	New Value
`--bar-border-radius`	`0px`	`$range-ios-bar-border-radius` (`2px` default)
`--knob-size`	`28px`	`$range-ios-knob-width` (`26px` default)
`$range-ios-bar-height`	`2px`	`4px`
`$range-ios-bar-background-color`	`rgba(var(--ion-text-color-rgb, 0, 0, 0), .1)`	`var(--ion-color-step-900, #e6e6e6)`
`$range-ios-knob-box-shadow`	`0 3px 1px rgba(0, 0, 0, .1), 0 4px 8px rgba(0, 0, 0, .13), 0 0 0 1px rgba(0, 0, 0, .02)`	`0px 0.5px 4px rgba(0, 0, 0, 0.12), 0px 6px 13px rgba(0, 0, 0, 0.12)`
`$range-ios-knob-width`	`28px`	`26px`

ionChange is no longer emitted when the value of ion-range is modified externally. ionChange is only emitted from user committed changes, such as dragging and releasing the range knob or selecting a new value with the keyboard arrows.
- If your application requires immediate feedback based on the user actively dragging the range knob, consider migrating your event listeners to using ionInput instead.
The debounce property's value value has changed from 0 to undefined. If debounce is undefined, the ionInput event will fire immediately.
Range no longer clamps assigned values within bounds. Developers will need to validate the value they are assigning to ion-range is within the min and max bounds when programmatically assigning a value.
The name property defaults to ion-r-${rangeIds++} where rangeIds is a number that is incremented for every instance of ion-range.

Searchbar

ionChange is no longer emitted when the value of ion-searchbar is modified externally. ionChange is only emitted from user committed changes, such as typing in the searchbar and the searchbar losing focus or pressing the "Enter" key.
- If your application requires immediate feedback based on the user typing actively in the searchbar, consider migrating your event listeners to using ionInput instead.
The debounce property has been updated to control the timing in milliseconds to delay the event emission of the ionInput event after each keystroke. Previously it would delay the event emission of ionChange.
The debounce property's default value has changed from 250 to undefined. If debounce is undefined, the ionInput event will fire immediately.
The detail payload for the ionInput event now contains an object with the current value as well as the native event that triggered ionInput.

Design tokens

Token	Previous Value	New Value
`--placeholder-opacity`	`0.5`	`0.6`

Segment

ionChange is no longer emitted when the value of ion-segment is modified externally. ionChange is only emitted from user committed changes, such as clicking a segment button or dragging to activate a segment button.
The type signature of value supports string | undefined. Previously the type signature was string | null | undefined.
- Developers needing to clear the checked segment item should assign a value of '' instead of null.

Select

ionChange is no longer emitted when the value of ion-select is modified externally. ionChange is only emitted from user committed changes, such as confirming a selected option in the select's overlay.
The icon CSS Shadow Part now targets an ion-icon component.

Design tokens

Token	Previous Value	New Value
`--placeholder-opacity`	`0.33`	`0.6`

Slides

ion-slides, ion-slide, and the IonicSwiper plugin have been removed from Ionic.

Developers using these components will need to migrate to using Swiper.js directly, optionally using the IonicSlides plugin. Guides for migration and usage are linked below:

Textarea

ionChange is no longer emitted when the value of ion-textarea is modified externally. ionChange is only emitted from user committed changes, such as typing in the textarea and the textarea losing focus.
- If your application requires immediate feedback based on the user typing actively in the textarea, consider migrating your event listeners to using ionInput instead.
The debounce property has been updated to control the timing in milliseconds to delay the event emission of the ionInput event after each keystroke. Previously it would delay the event emission of ionChange.
The debounce property's default value has changed from 0 to undefined. If debounce is undefined, the ionInput event will fire immediately.
ionInput dispatches an event detail of null when the textarea is cleared as a result of clear-on-edit="true".
The detail payload for the ionInput event now contains an object with the current value as well as the native event that triggered ionInput.

Design tokens

Token	Previous Value	New Value
`--placeholder-opacity`	`0.5`	`0.6`

Toggle

ionChange is no longer emitted when the checked property of ion-toggle is modified externally. ionChange is only emitted from user committed changes, such as clicking the toggle to set it on or off.
The --background and --background-checked variables have been renamed to --track-background and --track-background-checked, respectively.

Virtual Scroll

ion-virtual-scroll has been removed from Ionic.

Developers using the component will need to migrate to a virtual scroll solution provided by their framework:

Any references to the virtual scroll types from @ionic/core have been removed. Please remove or replace these types: Cell, VirtualNode, CellType, NodeChange, HeaderFn, ItemHeightFn, FooterHeightFn, ItemRenderFn and DomRenderFn.

Types

Overlay Attribute Interfaces

ActionSheetAttributes, AlertAttributes, AlertTextareaAttributes, AlertInputAttributes, LoadingAttributes, ModalAttributes, PickerAttributes, PopoverAttributes, and ToastAttributes have been removed. Developers should use { [key: string]: any } instead.

JavaScript Frameworks

Angular

Angular v14 is now required to use @ionic/angular and @ionic/angular-server. Upgrade your project to Angular v14 by following the Angular v14 update guide.
null values on form components will no longer be converted to the empty string ('') or false. This impacts ion-checkbox, ion-datetime, ion-input, ion-radio, ion-radio-group, ion-range, ion-searchbar, ion-segment, ion-select, ion-textarea, and ion-toggle.
The dev-preview environmentInjector property has been removed from ion-tabs and ion-router-outlet. Standalone component routing is now available without additional custom configuration. Remove the environmentInjector property from your ion-tabs and ion-router-outlet components.

React

@ionic/react and @ionic/react-router no longer ship a CommonJS entry point. Instead, only an ES Module entry point is provided for improved compatibility with Vite.

Vue

@ionic/vue and @ionic/vue-router no longer ship a CommonJS entry point. Instead, only an ES Module entry point is provided for improved compatibility with Vite.

Utilities

`hidden` attribute

The [hidden] attribute has been removed from Ionic's global stylesheet. The [hidden] attribute can continue to be used, but developers will get the native hidden implementation instead. The main difference is that the native implementation is easier to override using display than Ionic's implementation.

Developers can add the following CSS to their global stylesheet if they need the old behavior:

[hidden] {
  display: none !important;
}

Components

Datetime

The ion-datetime component has undergone a complete rewrite and uses a new calendar style. As a result, some of the properties no longer apply and have been removed.

ion-datetime now displays the calendar inline by default, allowing for more flexibility in presentation. As a result, the placeholder property has been removed. Additionally, the text and placeholder Shadow Parts have been removed.
The --padding-bottom, --padding-end, --padding-start, --padding-top, and --placeholder-color CSS Variables have been removed since ion-datetime now displays inline by default.
The displayFormat and displayTimezone properties have been removed since ion-datetime now displays inline with a calendar picker. To parse the UTC string provided in the payload of the ionChange event, we recommend using a 3rd-party date library like date-fns. Here is an example of how you can take the UTC string from ion-datetime and format it to whatever style you prefer:

import { format, parseISO } from 'date-fns';

/**
 * This is provided in the event
 * payload from the `ionChange` event.
 */
const dateFromIonDatetime = '2021-06-04T14:23:00-04:00';
const formattedString = format(parseISO(dateFromIonDatetime), 'MMM d, yyyy');

console.log(formattedString); // Jun 4, 2021

The pickerOptions and pickerFormat properties have been removed since ion-datetime now uses a calendar style rather than a wheel picker style.
The monthNames, monthShortNames, dayNames, and dayShortNames properties have been removed. ion-datetime can now automatically format these values according to your devices locale thanks to the Intl.DateTimeFormat API. If you wish to force a specific locale, you can use the new locale property:

<ion-datetime locale="fr-FR"></ion-datetime>

The open method has been removed. To present the datetime in an overlay, you can pass it into an ion-modal or ion-popover component and call the present method on the overlay instance. Alternatively, you can use the trigger property on ion-modal or ion-popover to present the overlay on a button click:

<ion-button id="open-modal">Open Datetime Modal</ion-button>
<ion-modal trigger="open-modal">
  <ion-datetime></ion-datetime>
</ion-modal>

Header

When using a collapsible large title, the last toolbar in the header with collapse="condense" no longer has a border. This does not affect the toolbar when the large title is collapsed.

To get the old style back, add the following CSS to your global stylesheet:

ion-header.header-collapse-condense ion-toolbar:last-of-type {
  --border-width: 0 0 0.55px;
}

Icons

Ionic 6 now ships with Ionicons 6. Please be sure to review the Ionicons 6.0.0 Changelog and make any necessary changes.

Input

The placeholder property now has a type of string | undefined rather than null | string | undefined.

Converted ion-modal to use Shadow DOM.

If you were targeting the internals of ion-modal in your CSS, you will need to target the backdrop or content Shadow Parts instead, or use the provided CSS Variables.

Developers dynamically creating modals using document.createElement('ion-modal') will now need to call modal.remove() after the modal has been dismissed if they want the modal to be removed from the DOM.

Converted ion-popover to use Shadow DOM.

If you were targeting the internals of ion-popover in your CSS, you will need to target the backdrop, arrow, or content Shadow Parts instead, or use the provided CSS Variables.

Developers dynamically creating popovers using document.createElement('ion-popover') will now need to call popover.remove() after the popover has been dismissed if they want the popover to be removed from the DOM.

Radio

The RadioChangeEventDetail interface has been removed. Instead, listen for the ionChange event on ion-radio-group and use the RadioGroupChangeEventDetail interface.

Searchbar

The showClearButton property now defaults to 'always' for improved usability with screen readers.

To get the old behavior, set showClearButton to 'focus'.

Select

The placeholder property now has a type of string | undefined rather than null | string | undefined.

Tab Bar

The default iOS tab bar background color has been updated to better reflect the latest iOS styles. The new default value is:

var(--ion-tab-bar-background, var(--ion-color-step-50, #f7f7f7));

Textarea

The placeholder property now has a type of string | undefined rather than null | string | undefined.

Toast

The --white-space CSS variable now defaults to normal instead of pre-wrap.

The default iOS toolbar background color has been updated to better reflect the latest iOS styles. The new default value is:

var(--ion-toolbar-background, var(--ion-color-step-50, #f7f7f7));

Config

Transition Shadow

The experimentalTransitionShadow config option has been removed. The transition shadow is now enabled when running in ios mode.

Angular

Config

The Config.set() method has been removed. See https://ionicframework.com/docs/angular/config for examples on how to set config globally, per-component, and per-platform.

Additionally, the setupConfig function is no longer exported from @ionic/angular. Developers should use IonicModule.forRoot to set the config instead. See https://ionicframework.com/docs/angular/config for more information.

React

Config

All Ionic React applications must now import setupIonicReact from @ionic/react and call it. If you are setting a custom config with setupConfig, pass your config directly to setupIonicReact instead:

Old

import { setupConfig } from '@ionic/react';

setupConfig({
  mode: 'md'
})

New

import { setupIonicReact } from '@ionic/react';

setupIonicReact({
  mode: 'md'
})

Note that all Ionic React applications must call setupIonicReact even if they are not setting custom configuration.

Additionally, the setupConfig function is no longer exported from @ionic/react.

Vue

Config

The setupConfig function is no longer exported from @ionic/vue. Developers should pass their config into the IonicVue plugin. See https://ionicframework.com/docs/vue/config for more information.

Tabs Config

Support for child routes nested inside of tabs has been removed to better conform to Vue Router's best practices. Additional routes should be written as sibling routes with the parent tab as the path prefix:

Old

const routes: Array<RouteRecordRaw> = [
  {
    path: '/',
    redirect: '/tabs/tab1'
  },
  {
    path: '/tabs/',
    component: Tabs,
    children: [
      {
        path: '',
        redirect: 'tab1'
      },
      {
        path: 'tab1',
        component: () => import('@/views/Tab1.vue'),
        children: {
          {
            path: 'view',
            component: () => import('@/views/Tab1View.vue')
          }
        }
      },
      {
        path: 'tab2',
        component: () => import('@/views/Tab2.vue')
      },
      {
        path: 'tab3',
        component: () => import('@/views/Tab3.vue')
      }
    ]
  }
]

New

const routes: Array<RouteRecordRaw> = [
  {
    path: '/',
    redirect: '/tabs/tab1'
  },
  {
    path: '/tabs/',
    component: Tabs,
    children: [
      {
        path: '',
        redirect: 'tab1'
      },
      {
        path: 'tab1',
        component: () => import('@/views/Tab1.vue')
      },
      {
        path: 'tab1/view',
        component: () => import('@/views/Tab1View.vue')
      },
      {
        path: 'tab2',
        component: () => import('@/views/Tab2.vue')
      },
      {
        path: 'tab3',
        component: () => import('@/views/Tab3.vue')
      }
    ]
  }
]

In the example above tabs/tab1/view has been rewritten has a sibling route to tabs/tab1. The path field now includes the tab1 prefix.

Tabs Router Outlet

Developers must now provide an ion-router-outlet inside of ion-tabs. Previously one was generated automatically, but this made it difficult for developers to access the properties on the generated ion-router-outlet.

Old

<ion-tabs>
  <ion-tab-bar slot="bottom">
    ...
  </ion-tab-bar>
</ion-tabs>

<script>
  import { IonTabs, IonTabBar } from '@ionic/vue';
  import { defineComponent } from 'vue';

  export default defineComponent({
    components: { IonTabs, IonTabBar }
  });
</script>

New

<ion-tabs>
  <ion-router-outlet></ion-router-outlet>
  <ion-tab-bar slot="bottom">
    ...
  </ion-tab-bar>
</ion-tabs>

<script>
  import { IonTabs, IonTabBar, IonRouterOutlet } from '@ionic/vue';
  import { defineComponent } from 'vue';

  export default defineComponent({
    components: { IonTabs, IonTabBar, IonRouterOutlet }
  });
</script>

Overlay Events

Overlay events onWillPresent, onDidPresent, onWillDismiss, and onDidDismiss have been removed in favor of willPresent, didPresent, willDismiss, and didDismiss.

This applies to the following components: ion-action-sheet, ion-alert, ion-loading, ion-modal, ion-picker, ion-popover, and ion-toast.

Old

<ion-modal
  :is-open="modalOpenRef"
  @onWillPresent="onModalWillPresentHandler"
  @onDidPresent="onModalDidPresentHandler"
  @onWillDismiss="onModalWillDismissHandler"
  @onDidDismiss="onModalDidDismissHandler"
>
  ...
</ion-modal>

New

<ion-modal
  :is-open="modalOpenRef"
  @willPresent="onModalWillPresentHandler"
  @didPresent="onModalDidPresentHandler"
  @willDismiss="onModalWillDismissHandler"
  @didDismiss="onModalDidDismissHandler"
>
  ...
</ion-modal>

Utility Function Types

The IonRouter type for useIonRouter has been renamed to UseIonRouterResult.
The IonKeyboardRef type for useKeyboard has been renamed to UseKeyboardResult.

Browser and Platform Support

This section details the desktop browser, JavaScript framework, and mobile platform versions that are supported by Ionic Framework v6.

Minimum Browser Versions

Desktop Browser	Supported Versions
Chrome	60+
Safari	13+
Firefox	63+
Edge	79+

Minimum JavaScript Framework Versions

Framework	Supported Version
Angular	12+
React	17+
Vue	3.0.6+

Minimum Mobile Platform Versions

Platform	Supported Version
iOS	13+
Android	5.0+ with Chromium 60+ (See note below)

Starting with Android 5.0, the webview was moved to a separate application that can be updated independently of Android. This means that most Android 5.0+ devices are going to be running a modern version of Chromium. However, there are a still a subset of Android devices whose manufacturer has locked the webview version and does not allow the webview to update. These webviews are typically stuck at the version that was available when the device initially shipped.

As a result, Ionic Framework only supports Android devices and emulators running Android 5.0+ with a webview of Chromium 60 or newer. For context, this is the version that Stencil can support with no polyfills: https://stenciljs.com/docs/browser-support
