unsafelyUnwrapped
The wrapped value of this instance, unwrapped without checking whether the instance is nil.
Declaration
var unsafelyUnwrapped: Wrapped { get }Discussion
The unsafelyUnwrapped property provides the same value as the forced unwrap operator (postfix !). However, in optimized builds (-O), no check is performed to ensure that the current instance actually has a value. Accessing this property in the case of a nil value is a serious programming error and could lead to undefined behavior or a runtime error.
In debug builds (-Onone), the unsafelyUnwrapped property has the same behavior as using the postfix ! operator and triggers a runtime error if the instance is nil.
The unsafelyUnwrapped property is recommended over calling the unsafeBitCast(_:) function because the property is more restrictive and because accessing the property still performs checking in debug builds.
