Since SwiftUI doesnt have a Appdelegate file, I tried adding it through App.swift file.
However, it still doesnt work. What am i missing ?
imported the libraries
import AppTrackingTransparency
import AdSupport
class AppDelegate: NSObject, UIApplicationDelegate {
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool {func requestIDFA() {
ATTrackingManager.requestTrackingAuthorization(completionHandler: { status in
// Tracking authorization completed. Start loading ads here.
// loadAd()
})
}
Then called the appdelegate under #main
#main
struct MyApp: App {
#UIApplicationDelegateAdaptor(AppDelegate.self) var appDelegate
If you look at the didFinishLaunchingWithOptions function. You have a call function inside another function so the requestIDFA never calls.
Put your requestIDFA() function out side the didFinishLaunchingWithOptions and call inside the didFinishLaunchingWithOptions.
class AppDelegate: NSObject, UIApplicationDelegate {
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
requestIDFA()
return true
}
func requestIDFA() {
ATTrackingManager.requestTrackingAuthorization(completionHandler: { status in
// Tracking authorization completed. Start loading ads here.
// loadAd()
})
}
}
Note: Make sure you have an added key to your Info.plist.
<key>NSUserTrackingUsageDescription</key>
<string>Your reason, why you want to track the user</string>

I'm trying to use firebase firestore but keep getting this error:
Thread 1: "Failed to get FirebaseApp instance. Please call FirebaseApp.configure() before using Firestore"
This happens even though I do call FirebaseApp.configure() here:
class AppDelegate: NSObject, UIApplicationDelegate {
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool {
FirebaseApp.configure()
return true
}
}
And I have been using firebase authentication with no problems. Anyone know how to fix this?
I am building a screen with phone number login. I checked over and over again and the project is newly created, however, I am getting this log:
7.2.0 - [Firebase/Auth][I-AUT000015] The UIApplicationDelegate must handle remote notification for phone number authentication to work.
If app delegate swizzling is disabled, remote notifications received by UIApplicationDelegate need to be forwarded to FIRAuth's canHandleNotificaton: method.
I did read in the documentation about swizzling and I don't know why it seems to be disabled, I did not disabled it. I have added GoogleServices-Info.plist into the app, I added in firebase panel the app apn auth key.
My entry point in the app looks like this:
#main
struct partidulverdeApp: App {
init() {
FirebaseApp.configure()
}
var body: some Scene {
WindowGroup {
MainView()
.onOpenURL { url in
Auth.auth().canHandle(url.absoluteURL)
}
}
}
}
My URL Types property has an entry with the RESERVED_CLIENT_ID
I am very desperate about this problem. Any idea is highly appreciated.
Edit1:
I did read the documentation and tried to handle notification with swizzling disabled, but I get the same error:
class AppDelegate: NSObject, UIApplicationDelegate {
func application(_ application: UIApplication,
didReceiveRemoteNotification notification: [AnyHashable : Any],
fetchCompletionHandler completionHandler: #escaping (UIBackgroundFetchResult) -> Void) {
if Auth.auth().canHandleNotification(notification) {
completionHandler(.noData)
return
}
}
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool {
print("Your code here")
return true
}
}
#main
struct partidulverdeApp: App {
#UIApplicationDelegateAdaptor(AppDelegate.self) var appDelegate
init() {
FirebaseApp.configure()
}
var body: some Scene {
WindowGroup {
MainView()
.onOpenURL { url in
Auth.auth().canHandle(url.absoluteURL)
}
}
}
}
Here's how to implement Phone Number Auth using the new SwiftUI 2 life cycle:
Create a Firebase project and set up PhoneNumber Auth
Add your iOS app to the Firebase project, download and add GoogleService-Info.plist to your project
In Xcode, select the application target and enable the following capabilities:
Push notifications
Background modes > Remote notifications
Create and register an APNS authentication key on the Apple developer portal
Upload the key to Firebase (under Project Settings > Cloud messaging in the Firebase Console)
Add the Firebase project's reversed client ID to your app's URL schemes
In your Info.plist, set FirebaseAppDelegateProxyEnabled to NO
Implement the AppDelegate as follows:
class AppDelegate: NSObject, UIApplicationDelegate {
func application(_ application: UIApplication,
didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool {
FirebaseApp.configure()
print("SwiftUI_2_Lifecycle_PhoneNumber_AuthApp application is starting up. ApplicationDelegate didFinishLaunchingWithOptions.")
return true
}
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
print("\(#function)")
Auth.auth().setAPNSToken(deviceToken, type: .sandbox)
}
func application(_ application: UIApplication, didReceiveRemoteNotification notification: [AnyHashable : Any], fetchCompletionHandler completionHandler: #escaping (UIBackgroundFetchResult) -> Void) {
print("\(#function)")
if Auth.auth().canHandleNotification(notification) {
completionHandler(.noData)
return
}
}
func application(_ application: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any]) -> Bool {
print("\(#function)")
if Auth.auth().canHandle(url) {
return true
}
return false
}
}
#main
struct SwiftUI_2_Lifecycle_PhoneNumber_AuthApp: App {
#UIApplicationDelegateAdaptor(AppDelegate.self) var delegate
var body: some Scene {
WindowGroup {
ContentView()
.onOpenURL { url in
print("Received URL: \(url)")
Auth.auth().canHandle(url) // <- just for information purposes
}
}
}
}
For further reading, I suggest these two articles I wrote:
Firebase and the new SwiftUI 2 Application Life Cycle
The Ultimate Guide to the SwiftUI 2 Application Life Cycle
I've already followed this tutorial in both ways, by implementing the #available directives and by removing code/files, but still a black screen displays. Unless I'm missing something I think I've done both things properly.
This is the current status in the way of removing files/code:
SceneDelegate.swift deleted.
AppDelegate.swift like this:
import UIKit
#UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
return true
}
}
And finally Info.plist like this:
What am I missing so the screen still displays black due to the program not supporting versions previous to iOS 13?
Add this code in your AppDelegate file in didFinishLaunchingWithOptions method
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
if #available(iOS 13.0, *) {
} else {
let rootVC = //Initialize root controller
self.window?.rootViewController = rootVC
self.window?.makeKeyAndVisible()
}
return true
}
I guide you step by step.
1st remove SceneDelegate file from the project.
Add var window: UIWindow? to AppDelegate.
Remove below func from AppDelegate.
// 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.
}
Remove Application Scene Manifest key from Info.plist file.
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
let navigation = UINavigationController(rootViewController: ViewController())
let frame = UIScreen.main.bounds
window = UIWindow(frame: frame)
window!.rootViewController = navigation window!.makeKeyAndVisible()
return true
}
Extra
Add below delegate methods in AppDelegate file, below didFinishLaunchingWithOptions
func applicationWillResignActive(_ application: UIApplication) {
// Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state.
// Use this method to pause ongoing tasks, disable timers, and throttle down OpenGL ES frame rates. Games should use this method to pause the game.
}
func applicationDidEnterBackground(_ application: UIApplication) {
// Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later.
// If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits.
}
func applicationWillEnterForeground(_ application: UIApplication) {
// Called as part of the transition from the background to the inactive state; here you can undo many of the changes made on entering the background.
}
func applicationDidBecomeActive(_ application: UIApplication) {
// Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.
}
func applicationWillTerminate(_ application: UIApplication) {
// Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.
}
The way I currently load my data is in the viewWillAppear on their specific view controllers. My question is should I load all the data on the Home/Main View Controller and pass the data that way? Or is the current way Im doing it better?
I know this is subjective, I'm loading ALOT of data.
Structure:
If you do not want the data to persist between app processes (when the app is closed the data is cleared), you can use Global Variables. When it comes to retrieving data, I suggest you to create a function in AppDelegate called retrieveFromFirebase(), containing every piece of code needed to retrieve data in your app, for all the UIViewControllers of your app. Then you should call it inside
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {}
Then, inside your function, you should assign the snapshot's value to the global variable declared earlier.
Example:
This is an example of how to setup AppDelegate.swift for this:
import UIKit
import CoreData
import Firebase
//declaration of the global variable
var username = String()
#UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
FIRApp.configure()
retrieveFromFirebase()
return true
}
func retrieveFromFirebase(){
// get the data from Firebase
let ref = FIRDatabase.database().reference()
ref.child("username").observe(FIRDataEventType.value, with: { snapshot in
username = snapshot.value! as! String
})
}
// other methods from AppDelegate.swift
}
And when you get to the desired ViewController, set your viewDidAppear function to this:
override func viewDidAppear(_ animated: Bool){
super.viewDidAppear(animated)
yourLabel.text = username
}
And you can just use your username anywhere in the current Module.
Hope it helps!
I'm completely new to API's, and am following this tutorial on appcoda
https://www.appcoda.com/dropbox-api-tutorial/
It's been going very smoothly, but I've run into a problem, and given that I'm a novice, I don't have the first clue with how to fix it.
import UIKit
#UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
let appKey = "n00nzv68gtxk6c9" // Set your own app key value here.
let appSecret = "itumv0icksr7yj6" // Set your own app secret value here.
let dropboxSession = DBSession(appKey: appKey, appSecret: appSecret, root: kDBRootDropbox)
DBSession.setShared(dropboxSession)
return true
if DBSession.sharedSession().handleOpenURL(url) {
if DBSession.shared().isLinked() {
NotificationCenter.defaultCenter.postNotificationName("didLinkToDropboxAccountNotification", object: nil)
return true
}
}
return false
}
The problem is in the line
if DBSession.sharedSession().handleOpenURL(url) {
where I get the error
Use of unresolved identifier 'url'
What do I need to do?
Per the tutorial, you need to use the correct delegate method within AppDelegate.swift
// handle custom application schemes
func application(application: UIApplication, openURL url: NSURL, sourceApplication: String?, annotation: AnyObject?) -> Bool {
if DBSession.sharedSession().handleOpenURL(url) {
print("Url defined as \( url)")
}
}
