Private func didFinishLaunchingWithOptions not being called? (Swift 3)
for Swift ~3.0 Replace didFinishLaunchingWithOptions with follwing signature
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey : Any]? = nil) -> Bool {
}
Remove your method signature and have Xcode autocomplete it
I also had the problem that my didFinishLaunchingWithOptions
method in AppDelegate would not be called. My function was also marked private and looked like this
private func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool
The problem is that this is the old syntax! Apparently for me when I converted my project from Swift 2.x to Swift 3 Xcode did not convert the methods in AppDelegate. The new syntax looks like this
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey : Any]? = nil) -> Bool
Swift 4.2:
func application( _ application: UIApplication,didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool
