Getting an Error on this line
let appDelegate = UIApplication.sharedApplication().delegate as! AppDelegate
Could not cast value of type 'LLAppDelegateProxy' (0x2bd218) to
'MyAppName.AppDelegate' (0x2bc708).
I was setting a RootViewController in AppDelegate's didFinishLaunchingWithOptions method which suddenly stopped working. Any help will be appreciated. Thanks in advance.
It is possible get access to the original AppDelegate using automatic integration. Add the following static var to your AppDelegate class:
class AppDelegate: UIResponder, UIApplicationDelegate {
static var originalAppDelegate:AppDelegate!
Next, set that variable at the beginning of didFinishLaunchingWithOptions:
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
AppDelegate.originalAppDelegate = self
Now anytime you want access to your original AppDelegate you can retrieve it like so:
AppDelegate.originalAppDelegate.someMethod()

I'm trying to convert a method from the React-native Firebase documentation, from Objective-c code to Swift. But it's not working, can someone lend me a help?
The doc I'm following: https://rnfirebase.io/docs/v4.3.x/notifications/ios
This is the Object C part I want to convert and add to the Swift file:
- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification {
[[RNFirebaseNotifications instance] didReceiveLocalNotification:notification];
}
At the moment, this is my code, see the commented part:
import UIKit
import Firebase
#UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
var bridge: RCTBridge!
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
FirebaseApp.configure()
RNFirebaseNotifications.configure()
let jsCodeLocation: URL
jsCodeLocation = RCTBundleURLProvider.sharedSettings().jsBundleURL(forBundleRoot: "index", fallbackResource:nil)
let rootView = RCTRootView(bundleURL: jsCodeLocation, moduleName: "Zepplin", initialProperties: nil, launchOptions: launchOptions)
let rootViewController = UIViewController()
rootViewController.view = rootView
self.window = UIWindow(frame: UIScreen.main.bounds)
self.window?.rootViewController = rootViewController
self.window?.makeKeyAndVisible()
return true
}
/*func application(_ application: UIApplication, didReceiveLocalNotification notification: [UILocalNotification: Any]?) -> Any {
RNFirebaseNotifications.instance(_, didReceiveLocalNotification, notification)
}*/
}
But of corse, it's not working, because the syntax is wrong... I'm not familiar with Swift.
Can someone lend me a hand?
I would be glad! Thankss in before-hand!!!
EDIT:
Sorry if my question was not clear enough. For me, the question was, "how to fix the syntax?", I knew that the syntax was wrong. I had nothing to add to my question, the error Xcode was giving me was expected, obvious because I don't know Objective-C, nor Swift, I was trying in my way. Even if I added the error to the question, I'm sure that something else would error too. That's why I asked if someone could convert it for me, it's only a few lines, so I think I was not asking too much.
Thanks #bsod, for mentionating the tool you posted in the comment!! This is exactly the tool I needed. I didn't know that something like this tool existed.
Thanks for everyone that helped me.
func application(_ application: UIApplication,
didReceive notification: UILocalNotification)
But this method is deprecated. You might want to consider migrating to the "UNUserNotificationCenter" related APIs.
Hey I am trying to initialise a realm object in my app outside the app delegate.
Now, Since a lot of file in my app are accessing the realm file, i decide to declare it globally.
Now, by doing that I got an app rejection, reasoning crash due to this object. My code is as follows
AppDelegate.swift
import UIKit
import RealmSwift
var uiRealm = try! Realm()
#UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate, MessagingDelegate {
var window: UIWindow?
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
return true
}
In the above code the object is initialised as the app starts and any other methods loads.
Is it possible that I just declare an object or type Realm and the initialise it under didFinishLaunching as follows:
import UIKit
import RealmSwift
var uiRealm : Realm!
#UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate, MessagingDelegate {
var window: UIWindow?
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// I initialise it here
uiRealm = try! Realm()
return true
}
Will it make a difference if its declare in such form. I am a little timid about this.
Any help is highly appreciated.
P.S: I already tried declaring the realm variable in app delegate and the calling it in other classes by UIapplication.shared.delegatemethod, and it always crashes.
I am a self-taught newcomer to iOS programming and have worked through one beginner textbook. I'm trying to publish my first mobile application so I am going back through and cleaning up my code. The textbook I used stressed 'Dependency Injection' but I've struggled adapting their simple example to a more complex application.
The app operates as a shell and retrieves/parses txt files to populate. I successfully connected my model, which retrieves/parses the data, and the TableViewController that needs populated using the following code:
MyTableViewController {
var data: Data!
}
AppDelegate {
var window: UIWindow?
let data = Data()
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
let navCon = window!.rootViewController as! MyNavigationController
let tableVC = navCon.topViewController as! MyTableViewController
tableVC.data = data
return true
}
I then embedded that NavigationController within a TabBarController because the app will have other tabs. I tried the same process of setting the rootViewController and then drilling down until I could set my data variable, but I can't find the correct way to layer the ViewControllers and keep getting the error;
'fatal error: unexpectedly found nil while unwrapping an Optional value'
I tried two different approaches:
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
let tabBarCon = window!.rootViewController as! MyTabBarController
let navCon = tabBarCon.presentedViewController as! MyNavigationController
let tableVC = navCon.topViewController as! MyTableViewController
tableVC.data = data
return true
}
and
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
let tabBarCon = window!.rootViewController as! MyTabBarController
let navCon = MyNavigationController()
tabBarCon.viewControllers = [navCon]
let tableVC = navCon.topViewController as! MyTableViewController
tableVC.data = data
return true
}
Is there a solution to correct this error or am I going about this process wrong? Again, I have a file that pulls in a txt file and then creates a dictionary. I need a separate TableViewController to be able to access that dictionary to populate itself, but I want to achieve this in the most efficient and apple promoted manner, not all in the same file as I did in my first design.
Thanks for the help!
For Dependency Injection I do recommend you use Typhoon. From mine experience it's one of the best tool. This will help you to achive app asembly like:
/*
* This is the definition for our AppDelegate. Typhoon will inject the specified properties
* at application startup.
*/
public dynamic func appDelegate() -> AnyObject {
return TyphoonDefinition.withClass(AppDelegate.self) {
(definition) in
definition.injectProperty("cityDao", with: self.coreComponents.cityDao())
definition.injectProperty("rootViewController", with: self.rootViewController())
}
}
I found the solution through this thread;
Aassigning a value to a view controller from AppDelegate.swift
The result can be achieved by reconfiguring the second solution I attempted;
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
let tabBarCon = window!.rootViewController as! MyTabBarController
let tabBarRootVCs: Array = tabBarCon.viewControllers!
let navCon = tabBarRootVCs[0] as! MyNavigationController
let tableVC = navCon.topViewController as! MyTableViewController
tableVC.data = data
return true
}
I am trying to Access the MDM using AppConnect SDK in swift 1.2 but it is giving following error :
[AppConnect:Error] AppConnect cannot be instantiated directly.
Instead, call +initWithDelegate: and then +sharedInstance.
Code Snippet :
import UIKit
#UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate, AppConnectDelegate {
var window: UIWindow?
var appct = AppConnect()
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// Override point for customization after application launch.
// Initialize the AppConnect library
AppConnect.initWithDelegate(self)
self.appct = AppConnect.sharedInstance()
self.appct.startWithLaunchOptions(launchOptions)
return true
}
}
Application is crashing while accessing the Keys of MobileIron Backend Config file.
Any other way to implement this?
You are initializing AppConnect without delegate
change
var appct = AppConnect();
to
var appct : AppConnect!;
My solution was to set a new key/value in the plist:
Principal class AppConnectUIApplication
or in source mode:
<key>NSPrincipalClass</key>
<string>AppConnectUIApplication</string>
Hope it help you
I am integrating chartboost into my sprite kit game and have successfully integrated bridging files into my swift code. Now in my app delegate I have the following:
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// Override point for customization after application launch.
let kChartboostAppID = "5554c8680d60255c6a0f4af4"
let kChartboostAppSignature = "1d0e271cd054c9a63473d2f1212ca33a2922a19f"
Chartboost.startWithAppId(kChartboostAppID, appSignature: kChartboostAppSignature, delegate: self)
Chartboost.cacheMoreApps(CBLocationHomeScreen)
return true
}
class func showChartboostAds()
{
Chartboost.showInterstitial(CBLocationHomeScreen);
}
func didFailToLoadInterstitial(location: String!, withError error: CBLoadError) {
}
the startWithId line gives me an error that it cant invoke this method with these arguments ( String, String, AppDelegate). This used to work fine on my objective c code.. Anyone knows how to fix this?
class AppDelegate: UIResponder, UIApplicationDelegate, ChartboostDelegate
Edit (from Lalit's comment below)
In startWithAppId the delegate is set to self, so you have to set the class AppDelegate as the delegate, which is done using:
ChartboostDelegate(protocol)
