You can&#39;t use a production certificate in debug/development. Even if you do it, then, when you &#39;Archive&#39;, Xcode will automatically set it to production ([Apple reference][1]). You can see this when you try to submit your app to iTunes connect for TestFlight/Review or for Adhoc deployment.

There is a known bug in Xcode whereby manually setting this to &#39;production&#39; causes Xcode to display an error next to your entitlements config with a &#39;Fix Issue&#39; button. Clicking this sets it back to &#39;development&#39; This is **not** intended functionality. As I said it is a known issue and I believe I filed a radar when I first discovered it.

It has been fixed in Xcode 8.3 beta 2. In the meantime, manually set it to &#39;production&#39; and then ignore the error Xcode gives you, your project will work just fine.

XCode 10.2:

If you change your target to &quot;Generic iOS Device&quot; before Archive it will set the aps-environment variable to production. If you archive with the target set to your device it will archive with the aps-environment variable set to development.

I get from a RESTful Service the following data:

    [
      {
        &quot;id&quot;: 42,
        &quot;type&quot;: 0,
        &quot;name&quot;: &quot;Piety was here&quot;,
        &quot;description&quot;: &quot;Bacon is tasty, tofu not, ain&#39;t nobody like me, cause i&#39;m hot...&quot;,
      }...


And I&#39;m mapping with this class:

    export enum Type {
      Info,
      Warning,
      Error,
      Fatal,
    }
    
    
    export class Message{
      public id: number;
      public type: Type:
      public name: string;
      public description: string;
    }



But when I access &#39;type&#39; in Angular2 I get only a int value. But I&#39;d like to get a string value.

e.g:

    &#39;message.type=0&#39;
    {{message.type}} =&gt; should be Info
    &#39;message.type=1&#39;
    {{message.type}} =&gt; should be Warning

I would like to modify Android OS (official image from AOSP) to add preprocessing to a normal phone call playback sound.

I&#39;ve already achieved this filtering for app audio playback (by modifying *HAL* and *audioflinger*).

I&#39;m OK with targeting only a specific device (Nexus 5X). Also, I only need to filter playback - I don&#39;t care about recording (uplink).

*UPDATE #1:* 

To make it clear - I&#39;m OK with modifying Qualcomm-specific drivers, or whatever part that it is that runs on Nexus 5X and can help me modify in-call playback.


*UPDATE #2:* 

I&#39;m attempting to create a Java layer app that routes the phone playback to the music stream in real time.

I&#39;ve already succeeded in installing it as a system app, getting permissions for initializing `AudioRecord` with `AudioSource.VOICE_DOWNLINK`. However, the recording gives blank samples; it doesn&#39;t record the voice call.

This is the code inside my worker thread:

    // Start recording
    int recBufferSize = AudioRecord.getMinBufferSize(44100, AudioFormat.CHANNEL_IN_STEREO, AudioFormat.ENCODING_PCM_16BIT);
    mRecord = new AudioRecord(MediaRecorder.AudioSource.VOICE_DOWNLINK, 44100, AudioFormat.CHANNEL_IN_STEREO, AudioFormat.ENCODING_PCM_16BIT, recBufferSize);

    // Start playback
    int playBufferSize = AudioTrack.getMinBufferSize(44100, AudioFormat.CHANNEL_OUT_STEREO, AudioFormat.ENCODING_PCM_16BIT);
    mTrack = new AudioTrack(AudioManager.STREAM_MUSIC, 44100, AudioFormat.CHANNEL_OUT_STEREO, AudioFormat.ENCODING_PCM_16BIT, playBufferSize, AudioTrack.MODE_STREAM);

    mRecord.startRecording();;
    mTrack.play();

    int bufSize = 1024;
    short[] buffer = new short[bufSize];
    int res;
    while (!interrupted())
    {
        // Pull recording buffers and play back
        res = mRecord.read(buffer, 0, bufSize, AudioRecord.READ_NON_BLOCKING);
        mTrack.write(buffer, 0, res, AudioTrack.WRITE_BLOCKING);
    }

    // Stop recording
    mRecord.stop();
    mRecord.release();
    mRecord = null;

    // Stop playback
    mTrack.stop();
    mTrack.release();;
    mTrack = null;


I&#39;m running on a Nexus 5X, my own AOSP custom ROM, Android 7.1.1. I need to find the place which will allow call recording to work - probably somewhere in `hardware/qcom/audio/hal` in platform code.

Also I&#39;ve been looking at the function `voice_check_and_set_incall_rec_usecase` at `hardware/qcom/audio/hal/voice.c` However, I wasn&#39;t able to make sense of it (how to make it work the way I want it to).

*UPDATE #3:*

  I&#39;ve opened [a more-specific question](https://stackoverflow.com/questions/43818736/call-recording-make-audiosource-voice-downlink-work-on-nexus-5x-rooting-or-cu) about using `AudioSource.VOICE_DOWNLINK`, which might draw the right attention and will eventually help me solve this question&#39;s problem as well.

My React Native app works in the XCode simulator with no issues, but when I run in a physical device, my iPhone, there&#39;s a problem. The app launches and gets stuck on the React Native splash screen, the after 10-15 seconds the app crashes/closes. What&#39;s the cause of this and how can I prevent it?

I have working open webLink url codes in `Swift3` but when I use it gives me this warning;

&gt;&#39;openURL&#39; was deprecated in iOS 10.0: Please use openURL:options:completionHandler: instead

How can I resolve it, my codes under below.

    let myUrl = &quot;http://www.google.com&quot;
     if !myUrl.isEmpty {
                                    UIApplication.shared.openURL(URL(string: &quot;\(myUrl)&quot;)!)
                                }

Thank you.

I would like the UICollectionView (The red one) to shrink to the height of the content size in this case UICollectionViewCells(the yellow ones) because there is a lot of empty space. What I tried is to use:

    override func layoutSubviews() {
        super.layoutSubviews()
        if !__CGSizeEqualToSize(bounds.size, self.intrinsicContentSize) {
            self.invalidateIntrinsicContentSize()
        }
    }
    
    override var intrinsicContentSize: CGSize {
        return self.collection.contentSize
    }

but `return self.collection.contentSize` always return (width, 0)
and for this reason it shrinks too much to value of height 30 (The value which I set in the XIB file for the height, although I have constaint &gt;= 30).

How to adjust height of UICollectionView to be the height of the content size of the UICollectionView?

So a while ago I deleted the /ios directory in my react native app (let&#39;s call it X). I&#39;ve been developing and testing using the android emulator but now I&#39;d like to make sure it works on ios with xcode simulator etc. 

So my current idea is to create a new react native bare project (let&#39;s call it Y) with ios folder, then follow [these steps][1] to rename Y so that it has the name of X and then moving the /ios directory from Y into X and trying to `run-ios`. 

I&#39;ll update here how that goes, but I wondered if there is a better way and has nobody been in this situation before?

I&#39;ve googled lots of things &#39;regenerate ios folder&#39; &#39;deleted ios folder&#39; &#39;add ios folder to existing..&#39; and nothing helpful. Maybe my googlefu isn&#39;t good enough but if anyone has any suggestions, much appreciated.

Step 2 will be making sure it compiles because of dependencies and stuff but for now my goal is to just get the /ios folder back in the project and for React Native to be aware of it&#39;s existence (it has all the necessary config).

Thanks

When sending notifications to iOS users, for some of them I get response status code 400 (BadDeviceToken) or code 410 (Unregistered).

From Apple documentation about &quot;BadDeviceToken&quot;:

&gt; The specified device token was bad. Verify that the request contains a valid token and that the token matches the environment.

What is the meaning of &quot;bad&quot;? I know for a fact that the device token was valid at some earlier time. What does a user do to make its device token bad? 

From documentation about &quot;Unregistered&quot;:

&gt; The device token is inactive for the specified topic.

Does this necceserally mean that the app has been deleted? Or there can be some other reasons for this response. 


What are the possible reasons to get APNs responses BadDeviceToken or Unregistered?

I can&#39;t get rid of this error!

[![][1]][1]


I have tried all sorts of things like clearing Derived Data(Preferences-&gt;Locations-&gt;click gray arrow to open Derived Data folder in Finder-&gt;right-click, move to trash), cleaning the project(CMD+Shift+K or Product-&gt;Clean), updating carthage and dependencies, checked other answers on StackOverflow (mostly adjustments in Build Settings/Phases), and recloned the app from github, etc.

The same project works on my collaborators computers..

EDIT:
From the current top-rated answer, I was able to debug a little further...I am still not sure how to fix though. It looks like I have something in the project twice? I looked and can&#39;t find anything showing up twice!

Linker Command failed with exit code 1 (use -v to see invocation), Xcode 8, Swift 3

When using Xcode 9, there are some compiler warnings saying `This function declaration is not a prototype`. It suggests to add `void` to the method body, which will resolve it. The issue I am having is that those warnings are also thrown for system-API&#39;s like `UIApplication` delegate-methods:

    - (void)application:(UIApplication *)application
        handleActionWithIdentifier:(NSString *)identifier
             forRemoteNotification:(NSDictionary *)userInfo
                  withResponseInfo:(NSDictionary *)responseInfo
                 completionHandler:(void (^)())completionHandler

This could be resolved by the following:

    - (void)application:(UIApplication *)application
        handleActionWithIdentifier:(NSString *)identifier
             forRemoteNotification:(NSDictionary *)userInfo
                  withResponseInfo:(NSDictionary *)responseInfo
                 completionHandler:(void (^)(void))completionHandler


Now I am wondering if the delegate methods will still work on the long-term or Apple will insert the `void` in later iOS 11 Beta versions. I am curious because if I include the `void` body, Xcode will complain about mismatching method-selectors (which makes sense). Did someone experience the same issue so far? 

&quot;This function declaration is not a prototype&quot; warning in Xcode 9

I have built my app using new Xcode 9 beta for ios 11. I have found an issue with UITabBar where items are spread through the UITabBar and title is right aligned to the image. I have tried changing the code to get it to work but still not successful. 

ios 10+ 

[![enter image description here][1]][1]

ios 11

[![enter image description here][2]][2]

I could change the position of title using `tabBarItem.titlePositionAdjustment`
But that is not my requirement as it should automatically come bellow the image itself. I tried setting `tabbar.itemPositioning to UITabBarItemPositioningCentered` and also tried changing `itemSpacing` and `width`, but still did not work. Can someone help me understand why this happens and how to fix this? I want it to like ios 10+ version and images are taken from the left most corner of an iPad.

ios 11 UITabBar UITabBarItem positioning issue

Using the latest Xcode 9 beta, I&#39;m seemingly completely unable to access properties on Swift classes. Even odder, I can access the class itself to instantiate it or whatever, but completely unable to access properties on it.

So if I have this Swift class:

    import UIKit
    
    class TestViewController: UIViewController {
        var foobar = true
    }

And I try to do this:

    TestViewController *testViewController = [[TestViewController alloc] init]; // success
    testViewController.foobar; // error

What exactly am I doing wrong? New project with Xcode 9.

I have been using Keyboard notifications without any problem and getting exact height of Keyboard.

    - (void)keyboardDidShow:(NSNotification *) notification{
        CGSize keyboardSize = [[[notification userInfo] objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue].size;
    
        NSLog(@&quot;%f&quot;,keyboardSize.height);}

but with iOS 11 the size of keyboard is 0 when the notification is called. 

What is the problem occurring in this scenario? I am using xcode 9 Beta 5

Flutter: Push notifications even if the app is closed

After uploading a Flutter app to App Store Connect, I got the following email warning:

&gt; Dear Developer,
&gt; 
&gt; We identified one or more issues with a recent delivery for your app,
&gt; &quot;[APP NAME]&quot;. Your delivery was successful, but you may wish to correct
&gt; the following issues in your next delivery:
&gt; 
&gt; **Missing Push Notification Entitlement** - Your app appears to register with the Apple Push Notification service, but the app
&gt; signature&#39;s entitlements do not include the &quot;aps-environment&quot;
&gt; entitlement. If your app uses the Apple Push Notification service,
&gt; make sure your App ID is enabled for Push Notification in the
&gt; Provisioning Portal, and resubmit after signing your app with a
&gt; Distribution provisioning profile that includes the &quot;aps-environment&quot;
&gt; entitlement. Xcode does not automatically copy the aps-environment
&gt; entitlement from provisioning profiles at build time. This behavior is
&gt; intentional. To use this entitlement, either enable Push Notifications
&gt; in the project editor&#39;s Capabilities pane, or manually add the
&gt; entitlement to your entitlements file. For more information, see
&gt; https://developer.apple.com/library/content/documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/HandlingRemoteNotifications.html#//apple_ref/doc/uid/TP40008194-CH6-SW1.
&gt; 
&gt; After you’ve corrected the issues, you can use Xcode or Application
&gt; Loader to upload a new binary to App Store Connect.
&gt; 
&gt; Best regards,
&gt; 
&gt; The App Store Team

I don&#39;t use push notifications in my app? Why am I getting this warning? And how do I remove the &quot;aps-environment&quot; entitlement, wherever and whatever that is?

**Note:** This App Store issue has appeared multiple times on SO, sometimes because people needed to add push notifications (see [this][1] and [this][2]) and sometimes because they didn&#39;t (see [this][3] and [this][4]). This appears to be Flutter related in my case, though, so I am adding a new question.
