Error:

tns-platform-declarations/ios/objc-x86_64/objc!OSLog.d.ts(178,15): error TS2417: Class static side 'typeof OSLogEnumerator' incorrectly extends base class static side 'typeof NSEnumerator'.
Types of property 'alloc' are incompatible.
Type '() => OSLogEnumerator' is not assignable to type '<ObjectType>() => NSEnumerator<ObjectType>'.
Type 'OSLogEnumerator' is not assignable to type 'NSEnumerator<ObjectType>'.
Types of property 'allObjects' are incompatible.
Type 'NSArray<NSObject>' is not assignable to type 'NSArray<ObjectType>'.
Type 'NSObject' is not assignable to type 'ObjectType'.
'NSObject' is assignable to the constraint of type 'ObjectType', but 'ObjectType' could be instantiated with a different subtype of constraint '{}'.
