fetchWebAuthTokenCompletionBlock

Declaration

var fetchWebAuthTokenCompletionBlock: ((String?, (any Error)?) -> Void)? { get set }

Discussion

The closure returns no value and takes the following parameters:

• If the operation is successful, the web authentication token; otherwise, nil.

• An error that contains information about a problem, or nil if the system successfully fetches the token.

The operation executes this closure only once. You must provide a closure capable of executing on a background thread, so any tasks that require access to the main thread must dispatch accordingly.
