I'm trying to build and run the iOS app with Xcode7 and iOS10 iPhone5s. It builds succeeds, but it crashes when launching. It has no problem when running with iOS9 or earlier. Please help me to detect what makes my app crush when iOS10.

what I tried:

  • set breakpoint in AppDelegate.
    the program goes to init() methods, but it doesn't reach application:willFinishLaunchingWithOptions:launchOptions or application:didFinishLaunchingWithOptions:launchOptions. I have no idea about which methods the program goes to after init().

  • use Instrument
    It's wired that it succeeds to launch the app when using Instrument, so I can't detect which process leak memory with Instrument.

  • checking CPU
    enter image description here

What I haven't tried:

  • delete one pod and build for every pod:
    it takes much time, that's why I haven't tried.

I think I have same problem. Though I'm using xcode 8.0 that contains iOS 10 sdk. I don't think you can build iOS 10 devices from xcode 7, I could be wrong though.

You could try downloading xcode 8 https://developer.apple.com/download/ also quick fix might be changing deployment target higher if it's really small like 6 or 7.

I hope this fix your problem. It's frustrating since the crash seems to happen before application code actually is started to process.

I finally found the solution for now. If I run the project with simulator with iOS10, Class PLBuildVersion is implemented in both... Then I found the solution here: https://stackoverflow.com/a/39532396/5341236
