Instance Method

application(_:didFailToContinueUserActivityWithType:error:)

Tells the delegate that the activity could not be continued.

Declaration

optional func application(_ application: UIApplication, didFailToContinueUserActivityWithType userActivityType: String, error: Error)

Parameters

application

Your shared app object.

userActivityType

The activity type that was attempted.

error

An error object indicating the reason for the failure.

Discussion

Use this method to let the user know that the specified activity could not be continued. If you do not implement this method, UIKit displays an error to the user with an appropriate message about the reason for the failure.

This method is not called if either application(_:willFinishLaunchingWithOptions:) or application(_:didFinishLaunchingWithOptions:) returns false.
