Application error when starting from AppStore or TestFlight, but it works fine

Question

My app update was rejected. In the rejection message, they wrote "Application crash on startup." Then I tried my application, but could not cope with it. So I used TestFlight and noticed that when I started my application from TestFlight or AppStore, it started at startup. But if I run my application in normal mode, it works without crashing. The fact is that this error has occurred since the iOS 10 update. Now my application in the store also crashes when launched from the AppStore, while it works normally for 2 weeks.

Apple sent me a crash log:

There are 4 more topics, but this is one of them, so I did not copy the rest. I did some research, and although I noticed that my crash log was not completely translated (for some strange reason, since I have all the dsyms, but anything), I was able to understand that I was crashing on line 217 ( tell me wrong). I know that SIGTRAP in most cases is thrown by NSExceptions. The string itself:

 let api = MyAppAPI.instance 

Instance is singleton. I suppose something in instantiation fails. Here is the code:

 static var instance: MyAppAPI = { return Singleton.instance }() class MyAppAPI: Manager { struct Singleton { static var configuration: NSURLSessionConfiguration = { var configuration = NSURLSessionConfiguration.defaultSessionConfiguration() let version = NSBundle.mainBundle().objectForInfoDictionaryKey("CFBundleShortVersionString") as? String ?? "" configuration.HTTPAdditionalHeaders = [ "Accept": "application/vnd.MyApp.api+json, application/json;q=0.9", "User-Agent": "MyApp iOS/\(version)", "X-API-Version": "1.0.1" ] return configuration }() static var instance = MyAppAPI(configuration: configuration) static var baseURL : NSURL! = nil } 

I am so desperately worried about this error, I tried several things that did not work. Am I looking for a suitable place? Is there anyone with a solution? Any help would be greatly appreciated. I am ready to give to anyone who finds a solution for me or helps me find a solution!

Answer 1

I found a solution to my problem.

As expected, it came from a func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool

Inside the function, I had let userInfo = launchOpts[UIApplicationLaunchOptionsRemoteNotificationKey] as! NSDictionary let userInfo = launchOpts[UIApplicationLaunchOptionsRemoteNotificationKey] as! NSDictionary .

I changed it to let userInfo = launchOpts[UIApplicationLaunchOptionsRemoteNotificationKey] as? NSDictionary let userInfo = launchOpts[UIApplicationLaunchOptionsRemoteNotificationKey] as? NSDictionary , and then checked if userInfo != nil to make all the code with userInfo in userInfo .

If this helps someone or someone is struggling with this problem, check all of yours ! and replace them with ? if necessary (at didFinishLaunchingWithOptions ), since starting from TestFlight / AppStore seems to be different from the parameters (just a hunch, not enough to state it).
