I have trouble with WCSession activateSession. I added this code in my viewDidLoad method, and it's crashing at activateSession call. sendMessage is also crashing.

if ([WCSession isSupported]) {
    [WCSession defaultSession].delegate = self;
    [[WCSession defaultSession] activateSession];
}

I though that problem my be with thread, but I debug it and these calls on main thread.

any idea what can be the problem?

here is crash log:

  • Share the console log. your code is fine. – Muneeba Jan 08 '16 at 10:38
  • Is there any other piece of code in your AppDelegate 's didfinishlaunchoption method? – Muneeba Jan 08 '16 at 10:49
  • yes, there is bunch of code. but i think problem is with session.delegate. i have move this code to init and viewdidload, and the same crash happens – toxicsun Jan 08 '16 at 10:51
  • The above code is fine.You are targeting watche os 2 , you have implemented all the required things. Did you run your app with above code commented out ? – Muneeba Jan 08 '16 at 10:54
  • this is happens when i'm runing ios app. on watchkit it works fine. – toxicsun Jan 08 '16 at 10:55
  • I never encounter this issue in my app. neither if i run my target iOS app only. Can u share ur code.? – Muneeba Jan 08 '16 at 11:02
  • The call stack method names (such as `performSwizzledWCSessionActivateSession`) makes it sound like you are doing some swizzling; my guess is something is going wrong there. What is the goal with the swizzling you are doing? – ccjensen Jan 08 '16 at 14:38
  • I'm not doing swizzling in my project. I think this is can be thread problem, i created new project and copy past the WCSession code and it works fine. what is strange to me is the session.delegate (see in this link: http://imgur.com/AfDmDZv) any idea what is CRWCSessionDelegateProxy? – toxicsun Jan 08 '16 at 14:58

I have Crittercism framwork in my app. Once i commented this line in my app delegate method all works fine.

[Crittercism enableWithAppID:CRITTERCISM_APP_ID];

If you are using Cirttercism in your app, make sure to write this line [[WCSession defaultSession] activateSession] before Crittercism. Seems they have watch 2.0 support and that's the cause of conflict.

Your code must be called before 

[Crittercism enableWithAppID:].
