performActionForShortcutItem in Xcode 8 beta 6

Question

Since I updated to Xcode 8 beta 6 I get a warning for:

application(_ application: UIApplication, performActionFor shortcutItem: UIApplicationShortcutItem, completionHandler: (Bool) -> Void)

"Instance method application(_:performActionFor:completionHandler:) nearly matches optional requirement application(_:performActionFor:completionHandler:) of protocol UIApplicationDelegate"

But the method I have in my code is the one that autocomplete fills in. Apparently the method has been changed because my shortcut items don't work anymore but I don't know how to fix it.

Answer 1

Command-click on UIApplicationDelegate, and you can find this:

(Or see the latests documentation of UIApplicationDelegate.)

optional public func application(_ application: UIApplication,
    performActionFor shortcutItem: UIApplicationShortcutItem,
    completionHandler: @escaping (Bool) -> Swift.Void)

Try changing your method header to:

func application(_ application: UIApplication,
    performActionFor shortcutItem: UIApplicationShortcutItem,
    completionHandler: @escaping (Bool) -> Void)
