title: App crash on device but works on simulator iOS
body: <p>App wasn't developed by me, but now I have to add some features. Code compiles add launches on simulator but immediately crash on real device (didFinishLaunchingWithOptions never calls). Xcode doesn't show any errors. I think the problem may be in pods and frameworks but don't know how to check if this so. I reinstalled pods and recreated framework dependences in project but no app still crash. I have only this info from Xcode
