I have a TVOS app that has been converted form Swift 2 to Swift 3 and I am getting the following error. I am unsure how to silence it.
'[UIApplicationLaunchOptionsKey : Any]?' is not convertible to '[String : NSString]'
It is showing up in this piece of code
appControllerContext.launchOptions["BASEURL"] = AppDelegate.TVBaseURL
if let launchOptions = launchOptions as? [String: AnyObject] {
for (kind, value) in launchOptions {
appControllerContext.launchOptions[kind] = value
}
}

You'd better work with [UIApplicationLaunchOptionsKey : Any] as it is.
How is this?
if let launchOptions = launchOptions {
for (kind, value) in launchOptions {
appControllerContext.launchOptions[kind.rawValue] = value
}
}
UPDATED
Seems the type of the property launchOptions of TVApplicationControllerContext is [String: Any], so you have no need to cast with as AnyObject.
try this code please and tell me what happen.
appControllerContext.launchOptions["BASEURL"] = AppDelegate.TVBaseURL
if let launchOptions = launchOptions as? [String: Any] {
for (kind, value) in launchOptions {
appControllerContext.launchOptions[kind] = value
}
}

This question already has answers here:
Where to configure Firebase in my iOS app in the new SwiftUI App life cycle without AppDelegate and SceneDelegate?
(2 answers)
Closed 1 year ago.
I made the front end of an application but now I have to make the back end and therefore print a DB the problem is that I have an error "Failed to get FirebaseApp instance. Please call FirebaseApp.configure() before using Firestore" :
App delegate :
class AppDelegate: NSObject, UIApplicationDelegate {
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool {
FirebaseApp.configure()
return true
}
}
DataBase :
struct New: Identifiable {
var id: String = UUID().uuidString
var news: String
}
class NewsViewModel: ObservableObject {
#Published var news = [New]()
private var db = Firestore.firestore()
func fetchDate() {
db.collection("News").addSnapshotListener { (querySnapshot, error) in
guard let documents = querySnapshot?.documents else {
print("No documents")
return
}
self.news = documents.map { (QueryDocumentSnapshot) -> New in
let data = QueryDocumentSnapshot.data()
let news = data["News"] as? String ?? "ya r"
return New(news: news)
}
}
}
}
Print DB :
NavigationView {
List(viewModel.news) { news in
VStack(alignment: .leading) {
Text(news.news)
}
.navigationTitle("News")
}
}
.onAppear() {
self.viewModel.fetchDate()
}
Thanks for help
Can you add it inside willFinishLaunchingWithOptions
func application(_ application: UIApplication, willFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool {
FirebaseApp.configure()
return true
}
I'm using Firebase Remote Config, I have some troubles to update values.
My values are updated only if I close and relaunch the app.
But never if my app enters in foreground.
The developer is activated, with no cache delay.
class AppDelegate: UIResponder, UIApplicationDelegate {
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
FirebaseApp.configure()
let _ = RCFirebaseValues.sharedInstance
}
}
My Firebase Remote Config class:
enum ValueKey: String {
case force_update
}
class RCFirebaseValues {
static let sharedInstance = RCFirebaseValues()
var loadingDoneCallback: (() -> ())?
var fetchComplete: Bool = false
private init() {
loadDefaultValues()
fetchCloudValues()
}
func loadDefaultValues() {
RemoteConfig.remoteConfig().setDefaults(fromPlist: "RemoteConfigDefaults")
}
func fetchCloudValues() {
#if DEBUG
let expirationDuration: TimeInterval = 0
RemoteConfig.remoteConfig().configSettings = RemoteConfigSettings(developerModeEnabled: true)
#else
let expirationDuration: TimeInterval = 3600
#endif
RemoteConfig.remoteConfig().fetch(withExpirationDuration: expirationDuration) {
[weak self] (status, error) in
guard error == nil else {
DLog(message:"Uh-oh. Got an error fetching remote values \(String(describing: error))")
return
}
RemoteConfig.remoteConfig().activateFetched()
self?.fetchComplete = true
self?.loadingDoneCallback?()
}
}
func bool(forKey key: ValueKey) -> Bool {
return RemoteConfig.remoteConfig()[key.rawValue].boolValue
}
func string(forKey key: ValueKey) -> String {
return RemoteConfig.remoteConfig()[key.rawValue].stringValue ?? ""
}
func double(forKey key: ValueKey) -> Double {
if let numberValue = RemoteConfig.remoteConfig()[key.rawValue].numberValue {
return numberValue.doubleValue
} else {
return 0.0
}
}
}
What's wrong?
EDIT after Mosbah's response:
class AppDelegate: UIResponder, UIApplicationDelegate {
var remoteConfig:RCFirebaseValues!
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
FirebaseApp.configure()
self. remoteConfig = RCFirebaseValues.sharedInstance
}
}
Your RCFirebaseValues scope is wrong, it will be nil as soon as you are out of application: didFinishLaunchingWithOptions: so you should keep a strong reference to your object (create a var on AppDelegate).
I'm working on an app that receives data from a remote notification, I'm trying to pass that data from didFinishLaunchingWithOptions to my ViewController using Notificationcenter when opening the app through tapping on the notification using launchOptions. The problem is that the observer on my viewDidAppear is not getting any data.
This is my code on the didFinishLaunchingWithOptions method:
func application(_ application: UIApplication,
didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
if let remoteNotification = launchOptions?[.remoteNotification] as? [AnyHashable : Any] {
let nameSchool = remoteNotification["name_school" as! String]
NotificationCenter.default.post(name: Notification.Name.nameSchool, object: nameSchool)
}
}
And the observer in the viewDidAppear method:
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
NotificationCenter.default.addObserver(forName: Notification.Name.nameSchool, object: nil, queue: OperationQueue.main) { (nameSchool) in
let schoolName = nameSchool.object as! String
self.messagePopup(message: "Data received")
}
}
Since your application(,didFinishLaunchingWithOptions:) will be called before the viewDidAppear (as per your comment), then you will have to temporarily store the result you get from the function until your code can retrieve it later.
#UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var remoteNotificationAtLaunch: [AnyHashable: Any]?
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
self.remoteNotificationAtLaunch = launchOptions?[.remoteNotification] as? [AnyHashable : Any]
}
...
}
Obviously keep the part you already have in your AppDelegate that generates the post to NotificationCenter when a remote notification is received. Then in your view controller, update your viewDidAppear...
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
observeNotifications()
checkForNotificationAtLaunch()
}
private func observeNotifications() {
NotificationCenter.default.addObserver(forName: Notification.Name.nameSchool, object: nil, queue: OperationQueue.main) { (nameSchool) in
let schoolName = nameSchool.object as! String
self.processNotification(schoolName: schoolName)
}
}
private func checkForNotificationAtLaunch() {
if let appDelegate = UIApplication.shared.delegate as? AppDelegate {
if let notificationAtLaunch = appDelegate.remoteNotificationAtLaunch,
let schoolName = notificationAtLaunch["name_school"] as? String {
processNotification(schoolName: schoolName)
}
}
}
private func processNotification(schoolName: String) {
self.messagePopup(message: "data received")
// do something with schoolName....
}
I am trying to handle the launch option and open a specific view controller upon tapping a remote notification that I receive in swift 3. I have seen similar question, for instance here, but nothing for the new swift 3 implementation. I saw a similar question (and ) In AppDelegate.swift I have the following in didFinishLaunchingWithOptions:
var localNotif = (launchOptions[UIApplicationLaunchOptionsRemoteNotificationKey] as! String)
if localNotif {
var itemName = (localNotif.userInfo!["aps"] as! String)
print("Custom: \(itemName)")
}
else {
print("//////////////////////////")
}
but Xcode is giving me this error:
Type '[NSObject: AnyObject]?' has no subscript members
I also tried this:
if let launchOptions = launchOptions {
var notificationPayload: NSDictionary = launchOptions[UIApplicationLaunchOptionsRemoteNotificationKey] as NSDictionary!
}
and I get this error:
error: ambiguous reference to member 'subscript'
I got similar errors wherever I had previously used similar code to get a value from a dictionary by the key and I had to replace the codes and basically safely unwrap the dictionary first. But that doesn't seem to work here. Any help would be appreciated. Thanks.
Apple made plenty of changes in Swift 3 and this one of them.
Edit: This works for Swift 4 as well.
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
//Launched from push notification
let remoteNotif = launchOptions?[UIApplicationLaunchOptionsKey.remoteNotification] as? [String: Any]
if remoteNotif != nil {
let aps = remoteNotif!["aps"] as? [String:AnyObject]
NSLog("\n Custom: \(String(describing: aps))")
}
else {
NSLog("//////////////////////////Normal launch")
}
}
Swift 5:
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
//Launched from push notification
guard let options = launchOptions,
let remoteNotif = options[UIApplication.LaunchOptionsKey.remoteNotification] as? [String: Any]
else {
return
}
let aps = remoteNotif["aps"] as? [String: Any]
NSLog("\n Custom: \(String(describing: aps))")
handleRemoteNotification(remoteNotif)
}
And for more on LaunchOptionsKey read Apple's documentation.
So it turned out the whole method signature has changed and when I implemented the new signature things worked just fine. Below is the code.
new didFinishLaunchingWithOptions method:
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey : Any]? = nil) -> Bool {
//and then
if launchOptions?[UIApplicationLaunchOptionsKey.remoteNotification] != nil {
// Do what you want to happen when a remote notification is tapped.
}
}
Hope this helps.
Swift 4
// Check if launched from the remote notification and application is close
if let remoteNotification = launchOptions?[.remoteNotification] as? [AnyHashable : Any] {
// Do what you want to happen when a remote notification is tapped.
let aps = remoteNotification["aps" as String] as? [String:AnyObject]
let apsString = String(describing: aps)
debugPrint("\n last incoming aps: \(apsString)")
}
swift 3:
if let notification = launchOptions?[.localNotification] as? NSDictionary{
#if DEBUG
print("iOS9 didFinishLaunchingWithOptions notification\n \(notification)")
#endif
if let remoteNotif = launchOptions?[UIApplicationLaunchOptionsKey.remoteNotification] as? [String: Any] {
if let notification = remoteNotif["aps"] as? [AnyHashable : Any] {
//handle PN
}
}
When the notification is clicked on I want it to open a specific page, but for some reason it keeps crashing with the error fatal error: unexpectedly found nil while unwrapping an Optional value. Why is this error happening? Am I opening the page correctly?
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
if let launchOptions = launchOptions as? [String : AnyObject] {
if let notificationDictionary = launchOptions[UIApplicationLaunchOptionsRemoteNotificationKey] as? [NSObject : AnyObject] {
self.application(application, didReceiveRemoteNotification: notificationDictionary)
let text = launchOptions["aps"]!["alert"]
print(text)
let viewController = storyBoard.instantiateViewControllerWithIdentifier("Player") as UIViewController
self.window?.rootViewController = viewController
}
}
return true
}
func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]) {
PFPush.handlePush(userInfo)
let text = userInfo["aps"]!["alert"]
print(text)
let viewController = storyBoard.instantiateViewControllerWithIdentifier("Player") as UIViewController
self.window?.rootViewController = viewController
}
Hope this will help :
