Declaration
var isAsynchronous: Bool { get }Discussion
The value of this property is true for operations that run asynchronously with respect to the current thread or false for operations that run synchronously on the current thread. The default value of this property is false.
When implementing an asynchronous operation object, you must implement this property and return true. For more information about how to implement an asynchronous operation, see Asynchronous Versus Synchronous Operations.
