App crashes on launch due to Spotify issue

We are working on a project where we are fetching feeds from Spotify. We have integrated Spotify library in the same. The app was rejected by MFI approval process due to app launch crash issue. We are stuck here. Its really urgent and we appreciate some quick help.

We are getting a app crash error when app launches. We are calling a method, which might be the reason of the crash but we are not sure.

- (void)clearKeychain {
  for( NSString *serviceName in @[@"rdio",@"spotify",@"spotifyUsername",@"muzik"]) {
    DDLogVerbose(@"removing keychain entry for service = %@", serviceName);
    [MZUserManager removeTokenForService:serviceName];
  }

MZSpotifyService *spotify = (MZSpotifyService*)[[MZDataManager sharedManager] serviceWithName:[MZSpotifyService shortName]];
  [spotify.sessionManager logout];

  [MZRdioService rdio].delegate = nil;
  [[MZRdioService rdio] logout];
}

---------------------------------

- (MZBaseService *)serviceWithName:(NSString *)serviceName
{
    NSLog(@"active services : \n %@",_activeServices);
  return _activeServices[serviceName];
}

---------------------------------------

- (void)logout {
  [[SPSession sharedSession] logout:^{
    DDLogVerbose(@"logged out from spotify");
  }];
}

Below are the logs

The important error is here:

The operation couldn’t be completed. (OSStatus error -34018 - client has neither application-identifier nor keychain-access-groups entitlements)

Now, as to why you're triggering it, I don't know. Try Googling that specific error — it's not Spotify-specific.

However, it looks like you're storing Spotify credentials in the Keychain, and you might be triggering the problem by clearing stuff from the Keychain. Unfortunately, "We are calling a method" isn't helpful information.

Now, you shouldn't be storing Spotify credentials in the Keychain. DEFINITELY not user passwords — that's a breach of the ToS. CocoaLibSpotify gives you token that are safe to store in NSUserDefaults.

You can find an example of how to store Spotify credentials properly in the "Empty CocoaLibSpotify" sample project that ships with the library.

Also, try testing your archive builds before submitting them to the App Store. There's no reason this shouldn't be triggering for you locally if it's happening during review.
