I have in my application Broadcast Upload extension. In broadcastStarted method I would like to, check does user is logged into my app. I've found how to do it in Apple WWDC presentation, but this resolve not works. Application does not streaming, but status bar showing that App still streaming. Here is my code:
override func broadcastStarted(withSetupInfo setupInfo: [String : NSObject]?) {
let condition = User.isLogged() // THIS IS FALSE
if(condition){
Uploader.startBroadcast(to: "demoChannel1")
}
else{
let userInfo = [NSLocalizedFailureReasonErrorKey: "Not Logged In"]
let error = NSError(domain: "RPBroadcastErrorDomain", code: 401, userInfo: userInfo)
finishBroadcastWithError(error)
print("User is not logged")
}
}
In console I can see message "User is not logged" but I see in status bar something like this
I have checked it in iPhone 8 Plus and iPhone 8 (iOS versions 13.4 and 13.3.1)
I will be grateful for any help

`Hi everyone, I am new to Swift and following a biometrics authentication tutorial to click a button and use Face ID or Touch ID.
Nothing happens when the biometric authentication button is pressed because canEvaluate etc do not get set to true. Details below.
variables and the relevant function
private(set) var context = LAContext()
#Published private(set) var biometryType: LABiometryType = .none
private(set) var canEvaluatePolicy = false
#Published private(set) var isAuthenticated = false`
func getBiometryType(){
context.canEvaluatePolicy(.deviceOwnerAuthenticationWithBiometrics, error: nil)
biometryType = context.biometryType
}
func authenticatedWithBiometrics() async {
context = LAContext()
print("inside auth func")
if canEvaluatePolicy{
let reason = "to log in to your account"
do{
let success = try await context.evaluatePolicy(.deviceOwnerAuthenticationWithBiometrics, localizedReason: reason)
print(success)
if success {
DispatchQueue.main.async {
self.isAuthenticated = true
print("is authenticated", self.isAuthenticated)
}
}
}
catch{ //if fail to authenticate, throw an error, show it, no biometry
print(error.localizedDescription)
DispatchQueue.main.async {
self.errorDescription = error.localizedDescription
self.showAlert = true
self.biometryType = .none
}
}
}
}
The issue: nothing happens when I click on the button that calls authenticatedwithbiometrics(). The function is called, the issue is that canEvaluatePolicy is FALSE and does not get set to true in getBiometryType. If I manually configure variables canEvaluatePolicy and success to true, we eventually run into the error.localizedDescription -> "biometry is not enrolled".
I've tried different simulators: iPhone 13, 14, 14 Pro, 14Pro Max, and SE which uses TouchID, and that also does nothing.
I've seen someone who had a same problem, but then it was solved by trying different simulators. That did not solve my issue.
I don't think it's an issue with the code because it's literally copied from a working tutorial. Do I need to configure something in the simulator?
Can we test Face ID in simulator? this type of answer is not useful to me because I cannot even evoke the gray popup that initiates the face or touch ID process.
I am using the newest version of xcode.
Thank you. `
I know why now. You have to restart the build after checking the "Enrolled face" button for the cue to show up.
You can used biometric authentication with simulator but you have to ensure you check enrolled in feature > FaceId > Enrolled after this you can check both scenarios Matching or Non Matching
I have enabled the entitlements for SIWA in the project target. And the same steps are working fine in the iOS simulator.
I am facing the following issue while trying to Sign in with Apple (SIWA) on the tvOS simulator.
Steps to reproduce the issue:
Upon requesting for SIWA on custom button tap, a full-screen layover displayed for the password of apple id (No option for choosing email relay was given) (screenshot attached in the last for reference)
Upon entering the correct password I get the callback in the error delegate.
Error in the error delegate:
error Error Domain=com.apple.AuthenticationServices.AuthorizationError Code=1000 "(null)"
Below is the code-snippet attached for the whole process.
I have done all the steps required as per the official document of SIWA for iOS.
FYI: The same code is working for iOS for me but not for the tvOS. I have tested SIWA in the iPhone simulator while development and now trying the same with the tvOS but it isn't working.
Below is my code.
Here, function setup( ) is called on viewDidLoad of ViewController
private func setup() {
if #available(tvOS 13.0, *) {
let appleIDProvider = ASAuthorizationAppleIDProvider()
appleIDProvider.getCredentialState(forUserID: "myapp.identifiers.currentUserIdentifier") { (credential, error) in
switch credential {
case .authorized:
print("authorized for sign in")
break
case .notFound, .revoked, .transferred:
print("ready to logout")
break
default:
print("Apple sign in credential state unidentified")
}
}
}
}
Inside the action method of the custom SIWA button, my code looks like
if #available(tvOS 13.0, *) {
let appleIDProvider = ASAuthorizationAppleIDProvider()
let request = appleIDProvider.createRequest()
request.requestedScopes = [.fullName, .email]
let authorizationController = ASAuthorizationController(authorizationRequests: [request])
authorizationController.delegate = self
authorizationController.presentationContextProvider = self
authorizationController.performRequests()
}
The presentation anchor is set in the extension of ViewController
extension ENWelcomeScreenViewController: ASAuthorizationControllerPresentationContextProviding {
#available(tvOS 13.0, *)
func presentationAnchor(for controller: ASAuthorizationController) -> ASPresentationAnchor {
return self.view.window!
}
}
And finally, the error delegate, in which I am receiving the callback.
/// - Tag: did_complete_error
#available(tvOS 13.0, *)
func authorizationController(controller: ASAuthorizationController, didCompleteWithError error: Error) {
print("error \(error)")
}
Here is how it looks when the user taps on SIWA button.
Any leads are highly appreciated.
The answer to my question is a big no!!
FINDINGS:
We can not test the sign in with apple in the tvOS simulator.
When I tried running the same on Apple TV it worked.
After entering the apple id credentials to sign-in in my app I get the push notification on the device I am signed-in with the same apple id.
Nothing happens when you tap on the received push notification.
On the Apple forum, I get a similar response from their engineering team.
Here is a screen capture of Apple TV.
Just had the same issue. The simple solution is to take the term "nearby" more than literally. Hold your phone really close to the Apple TV when tapping the notification and everything will do its magic.
I have searched enough but failed to get a solution.
I am using ReplayKit to record the screen of my app. I have started recording the screen by calling
let sharedRecorder = RPScreenRecorder.shared()
sharedRecorder.startRecording() { error in
if let error = error {
self.showScreenRecordingAlert(message: error.localizedDescription)
}
}
When I am pressing the stopRecord button I am calling
let sharedRecorder = RPScreenRecorder.shared()
sharedRecorder.stopRecording { previewViewController, error in
if let error = error {
self.showScreenRecordingAlert(message : error.localizedDescription)
return
}
}
But the issue that I am facing is, the program control does not enter inside the stopRecording block.
When I am doing po sharedRecorder.isRecording, it always returns false.
I have done everything I know but failed to get a solution.
If you having this above issue with your code i have found the solution for this.
let sharedRecorder = RPScreenRecorder.shared()
sharedRecorder.stopRecording { previewViewController, error in
if let error = error {
self.showScreenRecordingAlert(message : error.localizedDescription)
return
}}
Above Block will not call if you running your app on simulator so please use real device to test then above method will call definitely.
Thank you.
Just had this issue running XCode 9.4.1 and building onto iOS 11.4.0. Upgrading the phone to iOS 11.4.1 fixed the bug. I'm not sure if the difference in XCode versions is the root cause or if 11.4.0 was just broken.
I've running the latest Xcode 9 GM (13 Sep 2017) and have set Hardware > Face ID > Enrolled in simulator as well as Deployment Target 11.0. However I'm getting error code -6 LAErrorTouchIDNotAvailable.
Is there some setting I'm missing?
let myContext = LAContext()
let myLocalizedReasonString = "You are pretty"
var authError: NSError?
if #available(iOS 8.0, macOS 10.12.1, *) {
if myContext.canEvaluatePolicy(.deviceOwnerAuthenticationWithBiometrics, error: &authError) {
myContext.evaluatePolicy(.deviceOwnerAuthenticationWithBiometrics, localizedReason: myLocalizedReasonString) { success, evaluateError in
if success {
print("// User authenticated successfully, take appropriate action")
} else {
print(" // User did not authenticate successfully, look at error and take appropriate action")
}
}
} else {
print(" // Could not evaluate policy; look at authError and present an appropriate message to user")
}
} else {
print(" // Fallback on earlier versions")
}
Face ID does not work in the Xcode 9 GM due to a framework bug. Xcode 9.1 fixes this issue.
You can test your app in the iPhone 8 simulator and ensure it works correctly with Touch ID or run the Xcode 9.1 beta and test Face ID support there.
I think the iphone X simulator's faceID doesn't work at the moment, hopefully they will fix it soon...
https://forums.developer.apple.com/thread/86779
we could do a bug report to see if it speed things along :P
https://developer.apple.com/bug-reporting
Face ID is working now, with Xcode 9.1. Follow these steps to test it in Simulator.
Add privacy statement in your target's info.plist file.
Import LocalAuthentication framework to your project and add following code to your view controller and try with Face-ID
import LocalAuthentication
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
localAuthentication()
}
func localAuthentication() -> Void {
let laContext = LAContext()
var error: NSError?
let biometricsPolicy = LAPolicy.deviceOwnerAuthenticationWithBiometrics
if (laContext.canEvaluatePolicy(biometricsPolicy, error: &error)) {
if let laError = error {
print("laError - \(laError)")
return
}
var localizedReason = "Unlock device"
if #available(iOS 11.0, *) {
if (laContext.biometryType == LABiometryType.faceID) {
localizedReason = "Unlock using Face ID"
print("FaceId support")
} else if (laContext.biometryType == LABiometryType.touchID) {
localizedReason = "Unlock using Touch ID"
print("TouchId support")
} else {
print("No Biometric support")
}
} else {
// Fallback on earlier versions
}
laContext.evaluatePolicy(biometricsPolicy, localizedReason: localizedReason, reply: { (isSuccess, error) in
DispatchQueue.main.async(execute: {
if let laError = error {
print("laError - \(laError)")
} else {
if isSuccess {
print("sucess")
} else {
print("failure")
}
}
})
})
}
}
}
FaceID authentication will prompt you for first time to allow FaceID detection for your app.
Now enable Face ID enrolment and run your app to test Face ID simulation Testing.
Here is simulation result for matching and non-matching faces.
Result for matching face:
Result for non-matching face:
XCode 9.1 beta came out today in which the original code should work perfectly in the simulator!
According to Apples Documentation for LAContext, we need to add the key NSFaceIDUsageDescription with a reason of use String, as that will display the authorisation request for the use of FaceId on the device.
Example add this to info.plist:
NSFaceIDUsageDescription
set it to type String, and add a text that you want to be shown, in the prompt request for access to the Face ID camera.
"Your app" request your permission to use Face ID, for you to login to your account / unlock your notes / what ever reason in the end.
By adding this, you can go to the simulator for iPhone X, and you will be prompted for the Face ID, press accept, and everything should work perfectly.
Remember to enrol biometry support for the simulator by going into
Simulator -> Hardware -> Face ID / Touch ID -> Enrolled
Then you just need to pressed the Match / Non-Matching Touch / Face ID, to test out your handling
For more details and check out Apple's documentation: https://developer.apple.com/documentation/localauthentication/lacontext
---- Edit ----
This worked for me in both Xcode 9.0 and 9.1
I have a fairly simple app that parses a RSS feed and shows it's content in a table view. It's available on the App Store. I have Crashlytics crash reporting integrated. I recently received two reports. These are a little difficult to decipher.
This has occurred in an iPhone 6 running iOS 10.2.1.
This is from an iPhone 5 running iOS 10.2.1.
Even though it says it's crashing due to privacy violations, I'm not accessing any services that requires permission in my app.
Also searching on com.apple.root.default-qos lead me to believe that this may have something to do with background threads. The only place where I use a background thread is to parse the RSS feed data.
DispatchQueue.global(qos: .background).async {
guard let data = try? Data(contentsOf: URL) else {
return
}
do {
let xmlDoc = try AEXMLDocument(xml: data)
if let items = xmlDoc.root["channel"]["item"].all {
self.posts.removeAll()
for item in items {
let title = item["title"].value ?? ""
// ...
self.posts.append(jobPost)
}
DispatchQueue.main.async {
self.saveposts(self.posts)
self.posts.sort { $0.publishDate > $1.publishDate }
self.tableView.reloadData()
UIApplication.shared.toggleNetworkActivityIndicator(show: false)
self.toggleUI(enable: true)
if self.refreshControl.isRefreshing { self.refreshControl.endRefreshing() }
}
}
} catch let error as NSError {
print("RSS parsing failed: \(error)")
self.showErrorAlert(error)
UIApplication.shared.toggleNetworkActivityIndicator(show: false)
self.toggleUI(enable: true)
if self.refreshControl.isRefreshing { self.refreshControl.endRefreshing() }
}
}
I tested this code on my iPhone 5 running iOS 9.3.5 and simulators running iOS 10.2 but no crash occurred.
Is there any other way to track down this problem?
I would double check all your permissions. In my case, starting with iOS10 you need permissions to save stuff to the user's camera roll. In my app, I was showing a default share sheet and whenever a user selected "save photo" the app crashed with one of these very not helpful error messages. I added
<key>NSPhotoLibraryAddUsageDescription</key>
<string>Allow you to save charts and graphs from the app to your phone.</string>
to my info.plist, clean & run. And everything the problem was solved.
