makeAsyncIterator(): Observations_Iterator<number, NativeError>func makeAsyncIterator() -> Observations<Element, Failure>.IteratorCreates the asynchronous iterator that produces elements of this asynchronous sequence. - Returns: An instance of the `AsyncIterator` type used to produce elements of the asynchronous sequence.
next(): Promise<(number) | null>mutating func next(isolation iterationIsolation: isolated (any Actor)? = #isolation) async throws(Failure) -> Element?Asynchronously advances to the next element and returns it, or ends the sequence if there is no next element. - Returns: The next element, if it exists, or `nil` to signal the end of the sequence.
14 declarations were excluded from these bindings. Each reason comes from the generator or the iOS SDK compiler.
withContinuousObservation(options:apply:)
The iOS SDK compiler rejected this binding: parameter of noncopyable type 'ObservationTracking.Event' must specify ownership
ObservationTracking.Token.cancel()
The iOS SDK compiler rejected this binding: instance method 'receiver()' requires that 'ObservationTracking.Token' conform to 'Copyable'
ObservationRegistrar.access(_:keyPath:)
This declaration needs Swift generic type arguments. (no canonical witness for Subject)
ObservationRegistrar.willSet(_:keyPath:)
This declaration needs Swift generic type arguments. (no canonical witness for Subject)
ObservationRegistrar.didSet(_:keyPath:)
This declaration needs Swift generic type arguments. (no canonical witness for Subject)
ObservationRegistrar.withMutation(of:keyPath:_:)
This declaration needs Swift generic type arguments. (no canonical witness for Subject)
ObservationTracking.Event.kind
The iOS SDK compiler rejected this binding: instance method 'receiver()' requires that 'ObservationTracking.Event' conform to 'Copyable'
ObservationTracking.Event.matches(_:)
This parameter hides a concrete Swift type.
ObservationTracking.Event.cancel()
The iOS SDK compiler rejected this binding: instance method 'receiver()' requires that 'ObservationTracking.Event' conform to 'Copyable'
ObservationTracking.Options.init(arrayLiteral:)
A variable number of Swift arguments is not supported.
withObservationTracking(options:_:onChange:)
The iOS SDK compiler rejected this binding: parameter of noncopyable type 'ObservationTracking.Event' must specify ownership
withObservationTracking(_:onChange:)
callback cannot propagate synchronous failure
Observations.init(_:)
synchronous callback requires a nonescaping JS-thread call
Observations.untilFinished(_:)
synchronous callback requires a nonescaping JS-thread call
