Crashes on changing and scrolling the calendar from/in weekview/monthview

[hemangshah]

1. Using version: 7.0.6
2. Using the latest version: Yes
3. This should be a fresh issue.
4. Sample App? You can download it from here.
5. Description:

In my app, I have the functionality of changing the calendar view from month view to week view and vice versa. While being in week view or in month view, a user can also scrolls (changes) to the specific months (next or previous).

This leads to the crash.

I am not seeing any crash logs except below. It just stopped to the AppDelegate file.

Here's the crash log:

    libobjc.A.dylib`objc_retain:

I tried for quite some time, and could not reproduce your crash. I even did memory leaks profiling, and there was nothing. Every thing looked normal.

Here is something crazy -> you just updated to 7.0.6 right? It's possible the crash is related to XCode being silly after the pod update. Hence the reason there are no logs.

1. Do a project clean - CMD + SHIFT + K
2. Delete your generated Build for that project
3. delete your generate Derived Data folder for that project
4. re-run your project

If this does not work, I will arrange a time to do a share screen with you to debug it.

@patchthecode, thank you so much for investigation and as we found that, the issue is because of the older version of beta Xcode which I was using. I have tried the sample with the latest beta Xcode and it doesn't crash. So possibly, the issue is in Xcode. I will post back again if I will found the same issue till time closing this.
