  • XCode is full of these. We just feel lucky if we find a solution. If not ignore and hope it does not affect the app when it is on the market. – Ahmet Akkök Jul 15 '16 at 12:29

Basically it seems there is a breakpoint in the debugger. Thought it's not a solution, in order to run the app on the device, just click "Debug" and then "Continue" (or ^⌘Y). That should help pass the breakpoint and carry on running the app. "Debug" -> "Deactivate Breakpoints" can help too in some cases.

  • Unbelievable. Xcode 8.2 throwing this exception when loading a keyboard extension. – Dan Loughney Feb 13 '17 at 23:10
  • @DanLoughney, I am facing a similar issue for Keyboard extension. Have you resolved it? – KrishnaCA Mar 15 '17 at 05:20
  • After working with this a couple months I just need to call it fussy. Tons of time built into Xcode to build apps on iOS/macOS but no similar effort put into app extensions. It works or it doesn't. No way to know when, why, or how. Do clean cmd-shift-k and alt-cmd-shift-k when it happens. Also this is a **must** when changing from simulator to real device. – Dan Loughney Mar 17 '17 at 01:25

I Think the problem is within GLKit Framework.

So Try this out, make GLKit Framework optional in the path given below in the image and than build again.

The framework was being pulled into the build under

Project->BuildPhases->LinkBinaryWithLibraries.

Hope this Helps!

I too just started getting this breakpoint while running on an iPhone4 v 7.1.2. I'm not linking with GLKit.framework so this suggestion didn't help. I have had some success cleaning the library and reinstalling. After that it seems to be intermittent. Running outside the debugger works fine.

This is an old question but I face same problem and not found any answer. After some hours I find this cause by conflict constraints in autolayout story board. And this exception no longer occur after I fix all conflict constraints
