I am connecting firebase to xcode. I keep getting a THREAD 1 : SIGBART ERROR. I'm new to xcode so I don't know what to do. Please help. It gives me the error at the part where it says **class AppDelegate: UIResponder, UIApplicationDelegate {*

Please help me fix this. I really want to fix this. Thanks.

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:.
}
I am trying to implement the new iOS 13 background tasks functionality with a new app that is utilizing Scenes (also new). There are not a lot of examples, but the ones I have found were not using SceneDelegates, instead all the logic was contained in the AppDelegate. This causes issues since the event for the app going into the background is now raised in the SceneDelegate, not the AppDelegate.
This method does not fire in AppDelegate when using scenes
func applicationDidEnterBackground(_ application: UIApplication) {
}
This method does fire in SceneDelegate
func sceneDidEnterBackground(_ scene: UIScene) {
}
I am not able to find a corresponding SceneDelegate method for the following method in AppDelegate where all the examples show BGTaskScheduler registering tasks
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
BGTaskScheduler.shared.register(forTaskWithIdentifier: "UNIQUE_ID", using: DispatchQueue.global()) { task in
refreshMethod(task: task as! BGAppRefreshTask)
}
}
My question is whether there is some event in the SceneDelegate where I can register the task and if not what is the recommended pattern to follow for scene based apps.
AppDelegate.didFinishLaunchingWithOptions is still called at app launch, even when you have a SceneDelegate. So you should continue to register your background tasks in that method.
I followed this guide to integrate the push notifications into my app:
https://documentation.onesignal.com/docs/ios-sdk-setup
I followed the guide step-by-step but my app does not request for sending notifications, once installed even in the options I can't see notification service.
I implemented everything on an existing app, my doubts are about the AppDelegate.swift file, this is the full code:
import UIKit
import CoreData
import OneSignal
#UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {

return true
}
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 invalidate graphics rendering callbacks. 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 active 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:.
// Saves changes in the application's managed object context before the application terminates.
self.saveContext()
}

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {

return true

func applicationWillResignActive(_ application: UIApplication) {

I am trying to connect my app to firebase to send notification but there i have an error:
"_OBJC_CLASS_$_FIRApp", referenced from:
clang: error: linker command failed with exit code 1 (use -v to see invocation)
in the General Capabilities there is no any error.
in code the same there is no any error but when I build and Run there is this error.
While creating certificates also there is wasn't any errors.
Here is how the errror is look like . Please help!
Here is the piece of code that I wrote:

I would to change the background color of the "More" UINavigationController in my UITabBar. When I try to change the background color, it's not a good result. That is my code:
import UIKit
import SwiftyJSON
import FontAwesomeKit
#UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
application.registerUserNotificationSettings(UIUserNotificationSettings(forTypes: [.Alert, .Sound, .Badge], categories: nil))
// Override point for customization after application launch.
UITabBarItem.appearance().setTitleTextAttributes([NSForegroundColorAttributeName : UIColor.whiteColor()], forState: .Selected)
UITabBarItem.appearance().setTitleTextAttributes([NSForegroundColorAttributeName : UIColor.whiteColor()], forState: .Normal)
tabBarController.moreNavigationController.navigationBar.barStyle = .Default
tabBarController.moreNavigationController.navigationBar.backgroundColor = UIColor.orangeColor()
tabBarController.moreNavigationController.navigationBar.tintColor = UIColor.whiteColor()
return true
}
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 active 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:.
}
And this is the result:
Capture of UINavigationController
Change the barStyle to UIBarStyle.Black this will create a solid background and do also add
tabBarController.moreNavigationController.navigationBar.translucent = false
This should do the work for you.
