App crashes ONLY when connected to XCode

Question

My Swift app only seems to crash with EXC_BAD_ACCESS when my app is connected to XCode and I'm debugging. If I unplug my device and then run the app, it works flawlessly.

The app crashes at:

class AppDelegate: UIResponder, UIApplicationDelegate {

I'm pulling my hair out trying to solve this.

Answer 1

It's probably not a crash. More likely you have an Exception breakpoint and you're hitting it.

Answer 2

Try to replace your function with below one:

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {}

or

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]!) -> Bool {} 

Answer 3

That could be a pointer deallocating issue in the memory. That would be great if you can post more details about the error/crash info that you got, so that we can help you better. There are some solutions that you can try from this existing post, which was the similar problem(EXC_BAD_ACCESS) as you have: http://loufranco.com/blog/understanding-exc_bad_access

Answer 4

After a fiddling with the initial view controller I found that it only happened on the controller where my GMSMapView was. As it turns out, another user was having a similar problem here.

It turns out upgrading to iOS 8.4 solved the issue immediately. While I didn't use Dave's brilliant work around, I still give all the props and kudos to him!

Thank you everyone for sticking with me during this dark time in my life.
