I am trying to get the connectivity status of the iPhone and the Apple Watch. I have tried using CoreBluetooth which didn't work. I think I am on the right track but I need a bit of help. My code is below :)
AppDelegate.swift
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
if WCSession.isSupported() {
let session = WCSession.default
session.delegate = self
session.activate()
}
return true
}
Detail.swift
override func viewDidLoad() {
super.viewDidLoad()
if (WCSession.default.isPaired){
print("thumbsup")
} else{
print("thumbsdown")
}
}
you also have to check whether the activation state is active, otherwise isPaired should not be evaluated

How can I go to another view controller after successfully signing with google? I've tried "self.inputViewController?.performSegue(withIdentifier: "goToMain", sender: self)" in my App Delegate but not getting any respond. Am I supposed to add the method in App Delegate or the view controller with the sign-in button?
App Delegate
import UIKit
import Firebase
import GoogleSignIn
#UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate, GIDSignInDelegate{
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
FirebaseApp.configure()
GIDSignIn.sharedInstance()?.clientID = "my_client_id"
GIDSignIn.sharedInstance()?.delegate = self
return true
}
func sign(_ signIn: GIDSignIn!, didSignInFor user: GIDGoogleUser!, withError error: Error!) {
if let error = error {
print(error)
return
}
guard
let authentication = user?.authentication,
let idToken = authentication.idToken
else {
return
}
let credential = GoogleAuthProvider.credential(withIDToken: idToken,
accessToken: authentication.accessToken)
Auth.auth().signIn(with: credential) { authResult, error in
if let error = error {
let authError = error as NSError
print(authError.localizedDescription)
return
}
self.inputViewController?.performSegue(withIdentifier: "goToMain", sender: self)
}
}
func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool {
return GIDSignIn.sharedInstance().handle(url)
}
// MARK: UISceneSession Lifecycle
func application(_ application: UIApplication, configurationForConnecting connectingSceneSession: UISceneSession, options: UIScene.ConnectionOptions) -> UISceneConfiguration {
// Called when a new scene session is being created.
// Use this method to select a configuration to create the new scene with.
return UISceneConfiguration(name: "Default Configuration", sessionRole: connectingSceneSession.role)
}
func application(_ application: UIApplication, didDiscardSceneSessions sceneSessions: Set<UISceneSession>) {
// Called when the user discards a scene session.
// If any sessions were discarded while the application was not running, this will be called shortly after application:didFinishLaunchingWithOptions.
// Use this method to release any resources that were specific to the discarded scenes, as they will not return.
}
}
Are you sure about the inputViewController is not nil? This may a reason for not working.
You can add a function to test this, or you can use the print function to check, or, you can use debug point to check inputViewController is nil or not.
I'd like to add comment but I don't have enough reputation point :).
Good luck.
I am following this tutorial from Firebase to implement Direct Links into my app: Firebase Dynamic Links
My code in my app delegate never seems to run properly. When I run the project I am able to use the link and open the app. But none of the print statements will run so I can't tell if it ran successfully or not:
import UIKit
import Firebase
#main
class AppDelegate: UIResponder, UIApplicationDelegate {
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
FirebaseApp.configure()
return true
}
func handleincomingDynamicLink(_ dynamicLink: DynamicLink) {
guard let url = dynamicLink.url else {
print("Thats weird. My dynamic object link has no url")
return
}
print("Your incoming link parameter is \(url.absoluteString)")
}
func application(_ application: UIApplication, continue userActivity: NSUserActivity,
restorationHandler: #escaping ([UIUserActivityRestoring]?) -> Void) -> Bool {
let handled = DynamicLinks.dynamicLinks()
.handleUniversalLink(userActivity.webpageURL!) { dynamiclink, error in
guard error == nil else {
print("Found an error! \(error!.localizedDescription)")
return
}
if let dynamicLink = dynamiclink {
self.handleincomingDynamicLink(dynamicLink)
}
}
return handled
}
#available(iOS 9.0, *)
func application(_ app: UIApplication, open url: URL,
options: [UIApplication.OpenURLOptionsKey: Any]) -> Bool {
return application(app, open: url,
sourceApplication: options[UIApplication.OpenURLOptionsKey
.sourceApplication] as? String,
annotation: "")
}
func application(_ application: UIApplication, open url: URL, sourceApplication: String?,
annotation: Any) -> Bool {
if let dynamicLink = DynamicLinks.dynamicLinks().dynamicLink(fromCustomSchemeURL: url) {
return true
}
return false
}
// MARK: UISceneSession Lifecycle
func application(_ application: UIApplication, configurationForConnecting connectingSceneSession: UISceneSession, options: UIScene.ConnectionOptions) -> UISceneConfiguration {
// Called when a new scene session is being created.
// Use this method to select a configuration to create the new scene with.
return UISceneConfiguration(name: "Default Configuration", sessionRole: connectingSceneSession.role)
}
func application(_ application: UIApplication, didDiscardSceneSessions sceneSessions: Set<UISceneSession>) {
// Called when the user discards a scene session.
// If any sessions were discarded while the application was not running, this will be called shortly after application:didFinishLaunchingWithOptions.
// Use this method to release any resources that were specific to the discarded scenes, as they will not return.
}
}
Xcode gives me this error after I use the link:
[connection] nw_read_request_report [C1] Receive failed with error "Software caused connection abort"
use below delegate method in SceneDelegate Class:
func scene(_ scene: UIScene, continue userActivity: NSUserActivity)
Sorry if this is a repetative question but I have tried other people's answers here and none of the worked. I was to keep the user signed in after exiting my app. I am using email authentication and backend is Fire base. I tried implementing a function an app delegate but had no luck. any advice is appreciated.
override func viewDidAppear(_ animated: Bool) {
let auth = Auth.auth()
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
auth.addStateDidChangeListener { [weak self] (_, user) in
if user != nil {
let vc = self?.storyboard?.instantiateViewController(withIdentifier: "Profile")
self?.present(vc!, animated: true, completion: nil)
} else {
//
}
}
return true
}
}
Attempting to work with Firebase to register for remote notifications however when implementing the following code I get the error:
UNUserNotificationCenter is only available on iOS 10.0 or newer
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// Override point for customization after application launch.
var soundID: SystemSoundID = 0
let soundFile: String = NSBundle.mainBundle().pathForResource("symphony", ofType: "wav")!
let soundURL: NSURL = NSURL(fileURLWithPath: soundFile)
AudioServicesCreateSystemSoundID(soundURL, &soundID)
AudioServicesPlayAlertSound(soundID)
Fabric.with([Twitter.self])
//Firebase configuration
FIRApp.configure()
//Resource code from stackoverflow to create UNUserNotificationCenter
let center = UNUserNotificationCenter.current()
center.requestAuthorization(options:[.badge, .alert, .sound]) { (granted, error) in
// Enable or disable features based on authorization.
}
application.registerForRemoteNotifications()
return true
}
By doing a simple "Fix-it" doesn't resolve my issue by creating an if statement based on the OS version number. What should I be doing or thinking towards this solution for the UserNotifications framework?
For one thing, with the new UNUserNotificationCenter, you only want to register for remote notifications if the user grants permission. The way your code is setup, you're trying to do it regardless of permission which could be one of the reasons. You should do something like this:
import UserNotifications
...
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
UNUserNotificationCenter.current().requestAuthorization(options:[.badge, .alert, .sound]) { (granted, error) in
DispatchQueue.main.async {
UIApplication.shared.registerForRemoteNotifications()
}
}
return true
}
If you need to check if the user has an OS lower than iOS 10.0 - you could try something like this to include the old system:
if #available(iOS 10.0, *) {
UNUserNotificationCenter.current().requestAuthorization(options:[.badge, .alert, .sound]) { (granted, error) in
DispatchQueue.main.async {
UIApplication.shared.registerForRemoteNotifications()
}
}
} else {
application.registerUserNotificationSettings(UIUserNotificationSettings(forTypes: UIUserNotificationType.Sound | UIUserNotificationType.Alert |
UIUserNotificationType.Badge, categories: nil))
}
Let me know if this works, and if it's what you're trying to accomplish. If not, I'll remove my answer.
I need create in my app a code that receive a remote information and push it to user when app is on background, I read on web that I need to use didReceiveRemoteNotification on appDelegate, to use remote push notication. I read something about and I need keys and certificates, I do not understand how to use didReceiveRemoteNotification
I need to learn about to push remote notification and how to use. I would like a tutorial or example how create it using swift 2.3.
I used this link and I found it the most helpful
http://www.appcoda.com/push-notification-ios/
I used this app for testing
https://itunes.apple.com/us/app/easy-apns-provider-push-notification/id989622350?mt=12
This is the code I have in my AppDelegate
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
registerForPushNotifications(application)
print(UIDevice.currentDevice().identifierForVendor!.UUIDString)
return true
}
func registerForPushNotifications(application: UIApplication) {
let notificationSettings = UIUserNotificationSettings(
forTypes: [.Badge, .Sound, .Alert], categories: nil)
application.registerUserNotificationSettings(notificationSettings)
}
func application(application: UIApplication, didRegisterUserNotificationSettings notificationSettings: UIUserNotificationSettings) {
if notificationSettings.types != .None {
application.registerForRemoteNotifications()
}
}
func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {
let tokenChars = UnsafePointer<CChar>(deviceToken.bytes)
var tokenString = ""
for i in 0..<deviceToken.length {
tokenString += String(format: "%02.2hhx", arguments: [tokenChars[i]])
}
print("Device Token:", tokenString)
}
func application(application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: NSError) {
print("Failed to register:", error)
}
