If I set a breakpoint and start debugging mode, Xcode tried to read the attributes, and then Xcode crashes. The position of the breakpoints in the source code is not affected. I tried the following steps: After Xcode crashes:
- If the simulator still works, make sure that before closing it, select IOS Simulator → Reset Content And Settings.
- Close Simulator (CMD-Q)
- Window → Organizer → Delete Derived Data
- When debugging on ANY devices, uninstall the application from the device and fully launch the device.
- Launch Xcode
- Delete all breakpoints
- Product → (hold Alt / Option) Clear build folder
- Product → Cleaning
- Close Xcode again with Xcode-> Quit Xcode (NOTE: there must be a GRACEFUL Exit, so Xcode can correctly execute a full shutdown / clear cycle)
- Reboot Mac
- Run xcode
- When running in the simulator, select a different device to simulate than when it failed.
- Go through a trial run of your application (no breakpoints)
- If all goes well, start adding breakpoints (all exceptions are always a good starting point).
But Xcode still crashes and crashes and ... I used Xcode 7.1 and Yosemite (I can't update El Capitan).
