Since I updated my xcode to xcode 8 I am getting this warning:
Instance method
application(:didRegisterForRemoteNotificationsWithDeviceToken:)' nearly matches optional requirement 'application(:didRegisterForRemoteNotificationsWithDeviceToken:)' of protocol 'UIApplicationDelegate
Xcode is asking me to silence this warning by making this function private, but when I do the function is never been called (It is not being called in either ways).
I tried to delete the functions then making autocomplete fill it but nothing worked.
This is the function having the warning:
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
//
}
This is my complete appDelegate file:
@UIApplicationMain
class AppDelegate: UIResponder,UIApplicationDelegate,UNUserNotificationCenterDelegate,CLLocationManagerDelegate {
var window: UIWindow?
var locationManager:CLLocationManager?
var coordinate: CLLocationCoordinate2D?
func locationManagerStart() {
if locationManager == nil {
print("init locationManager")
locationManager = CLLocationManager()
locationManager!.delegate = self
locationManager!.desiredAccuracy = kCLLocationAccuracyBest
locationManager!.requestWhenInUseAuthorization()
}
print("have location manager")
locationManager!.startUpdatingLocation()
}
func locationManagerStop() {
locationManager!.stopUpdatingLocation()
}
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
//
let newLocation = locations.first!
coordinate = newLocation.coordinate
print("location updated")
}
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
}
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
registerForPushNotifications(application)
return true
}
func registerForPushNotifications(_: UIApplication) {

UNUserNotificationCenter.current().delegate = self
UNUserNotificationCenter.current().requestAuthorization(options: [.badge, .sound, .alert], completionHandler: {(granted, error) in
if (granted)
{
UIApplication.shared.registerForRemoteNotifications()
}
else{
//Do stuff if unsuccessful...
}
})
}
else{
}
}
func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {
print("I am not available in simulator \(error)")
}
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any]) {
print(userInfo)
}
func applicationWillTerminate(_ application: UIApplication) {
// Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.

self.saveContext()

return urls[urls.count-1]

}()

let coordinator = NSPersistentStoreCoordinator(managedObjectModel: self.managedObjectModel)
let url = self.applicationDocumentsDirectory.appendingPathComponent("SingleViewCoreData.sqlite")
var failureReason = "There was an error creating or loading the application's saved data."
do {
try coordinator.addPersistentStore(ofType: NSSQLiteStoreType, configurationName: nil, at: url, options: nil)
} catch {
// Report any error we got.
var dict = [String: AnyObject]()
dict[NSLocalizedDescriptionKey] = "Failed to initialize the application's saved data" as AnyObject?

let nserror = error as NSError

abort()

}
}
}
After weeks of searching finally solved! The problem was that I had a class named "Data", it didnot make any error in xcode 7 but whenever i add it in xcode 8 the registerForNotification function in the app delegate makes this error! Weird but finally solved by just changing the name of the class Data.
