func swift_deletedAsyncMethodError() asyncfunc withCheckedContinuation<T>(function: String, (CheckedContinuation<T, Never>) -> Void) async -> TSuspends the current task, then calls the given closure with a checked continuation for the current task.
func withCheckedThrowingContinuation<T>(function: String, (CheckedContinuation<T, Error>) -> Void) async throws -> TSuspends the current task, then calls the given closure with a checked throwing continuation for the current task.

Structures
struct AsyncCompactMapSequenceAn asynchronous sequence that maps a given closure over the asynchronous sequence’s elements, omitting results that don’t return a value.
struct AsyncDropFirstSequenceAn asynchronous sequence which omits a specified number of elements from the base asynchronous sequence, then passes through all remaining elements.
struct AsyncDropWhileSequenceAn asynchronous sequence which omits elements from the base sequence until a given closure returns false, after which it passes through all remaining elements.
struct AsyncFilterSequenceAn asynchronous sequence that contains, in order, the elements of the base sequence that satisfy a given predicate.
struct AsyncFlatMapSequenceAn asynchronous sequence that concatenates the results of calling a given transformation with each element of this sequence.
struct AsyncMapSequenceAn asynchronous sequence that maps the given closure over the asynchronous sequence’s elements.
struct AsyncPrefixSequenceAn asynchronous sequence, up to a specified maximum length, containing the initial elements of a base asynchronous sequence.
struct AsyncPrefixWhileSequenceAn asynchronous sequence, containing the initial, consecutive elements of the base sequence that satisfy a given predicate.
struct AsyncStreamAn asynchronous sequence generated from a closure that calls a continuation to produce new elements.
struct AsyncThrowingCompactMapSequenceAn asynchronous sequence that maps an error-throwing closure over the base sequence’s elements, omitting results that don’t return a value.
struct AsyncThrowingDropWhileSequenceAn asynchronous sequence which omits elements from the base sequence until a given error-throwing closure returns false, after which it passes through all remaining elements.
struct AsyncThrowingFilterSequenceAn asynchronous sequence that contains, in order, the elements of the base sequence that satisfy the given error-throwing predicate.
struct AsyncThrowingFlatMapSequenceAn asynchronous sequence that concatenates the results of calling a given error-throwing transformation with each element of this sequence.
struct AsyncThrowingMapSequenceAn asynchronous sequence that maps the given error-throwing closure over the asynchronous sequence’s elements.
struct AsyncThrowingPrefixWhileSequenceAn asynchronous sequence, containing the initial, consecutive elements of the base sequence that satisfy the given error-throwing predicate.
struct AsyncThrowingStreamAn asynchronous sequence generated from an error-throwing closure that calls a continuation to produce new elements.
struct CancellationErrorAn error that indicates a task was canceled.
struct CheckedContinuationA mechanism to interface between synchronous and asynchronous code, logging correctness violations.
struct ContinuousClockA clock that measures time that always increments but does not stop incrementing while the system is asleep.
struct SuspendingClockA clock that measures time that always increments but stops incrementing while the system is asleep.
struct TaskA unit of asynchronous work.
struct TaskGroupA group that contains dynamically created child tasks.
struct TaskPriorityThe priority of a task.
struct ThrowingTaskGroupA group that contains throwing, dynamically created child tasks.
struct UnownedJobA unit of scheduleable work.
struct UnownedSerialExecutorAn unowned reference to a serial executor (a
SerialExecutorvalue).struct UnsafeContinuationA mechanism to interface between synchronous and asynchronous code, without correctness checking.
struct UnsafeCurrentTaskAn unsafe reference to the current task.
Classes
class MainActorA singleton actor whose executor is equivalent to the main dispatch queue.
class TaskLocalProperty wrapper that defines a task-local value key.
Protocols
protocol ActorCommon protocol to which all actors conform.
protocol AnyActorCommon marker protocol providing a shared “base” for both (local)
Actorand (potentially remote)DistributedActortypes.protocol AsyncIteratorProtocolA type that asynchronously supplies the values of a sequence one at a time.
protocol AsyncSequenceA type that provides asynchronous, sequential, iterated access to its elements.
protocol ClockA mechanism in which to measure time, and delay work until a given point in time.
protocol ExecutorA service that can execute jobs.
protocol GlobalActorA type that represents a globally-unique actor that can be used to isolate various declarations anywhere in the program.
protocol SerialExecutorA service that executes jobs.
