DispatchQueue

Topics

Structures

• struct Attributes

Initializers

• convenience init(label: String, qos: DispatchQoS, attributes: DispatchQueue.Attributes, autoreleaseFrequency: DispatchQueue.AutoreleaseFrequency, target: DispatchQueue?)

Instance Properties

• var label: String
• var qos: DispatchQoS

Instance Methods

• func async(execute: DispatchWorkItem)
  Submits a work item for asynchronous execution on a dispatch queue.
• func async(group: DispatchGroup, execute: DispatchWorkItem)
  Submits a work item to a dispatch queue and associates it with the given dispatch group. The dispatch group may be used to wait for the completion of the work items it references.
• func async(group: DispatchGroup?, qos: DispatchQoS, flags: DispatchWorkItemFlags, execute: () -> Void)
  Submits a work item to a dispatch queue and optionally associates it with a dispatch group. The dispatch group may be used to wait for the completion of the work items it references.
• func asyncAfter(deadline: DispatchTime, execute: DispatchWorkItem)
  Submits a work item to a dispatch queue for asynchronous execution after a specified time.
• func asyncAfter(deadline: DispatchTime, qos: DispatchQoS, flags: DispatchWorkItemFlags, execute: () -> Void)
  Submits a work item to a dispatch queue for asynchronous execution after a specified time.
• func asyncAfter(wallDeadline: DispatchWallTime, execute: DispatchWorkItem)
  Submits a work item to a dispatch queue for asynchronous execution after a specified time.
• func asyncAfter(wallDeadline: DispatchWallTime, qos: DispatchQoS, flags: DispatchWorkItemFlags, execute: () -> Void)
  Submits a work item to a dispatch queue for asynchronous execution after a specified time.
• func getSpecific<T>(key: DispatchSpecificKey<T>) -> T?
• func setSpecific<T>(key: DispatchSpecificKey<T>, value: T?)
• func sync(execute:)
• func sync<T>(flags: DispatchWorkItemFlags, execute: () throws -> T) rethrows -> T
  Submits a block for synchronous execution on this queue.
