All exception break point is stopping for no reason on simulator

Question

This is very annoying, every time I\'m trying to debug on the simulator with \"all exception break point\", app stops for no reason on this line:

return UIAp         


        

Answer 1

An exception is being thrown, but the caller (e.g. in libFontParser and libTrueTypeScaler) is handling it and it is not reaching your program.

Unless you see other evidence of a problem (such as a log message) or the exception reaches your program, assume that the implementation is handling it. You can continue past these instances in the debugger without worry.

Answer 2

If you didn't find a problem in .plist file maybe the problem is in your .storyboard file.. Open it as source code from Xcode or in textView from Finder - search for <customFonts key="customFonts"> I had there some old irrelevant array/font inside...:) just deleted it and it stopped

Answer 3

I was just experiencing the same exact problem and tracked down the issue.

Make sure that all fonts that you specify in your Info.plist under Fonts provided by this application are actually in your application bundle.

Answer 4

As the backtrace shows, the app didn't stop for no reason. It stopped because an exception was thrown, and it looks like a C++ exception.

Unlike Objective-C, where exceptions should only be thrown as the result of programming errors and therefore are very rare, there is a lot of C++ code around that throws and catches lots of exceptions. In that situation, probably best to only set a breakpoint on Objective-C exceptions, not all exceptions.

Answer 5

In my case the reference was inside xcuserdata :

user$ grep -R "HelveticaNeue" ./
Binary file .//MyProject.xcworkspace/xcuserdata/user.xcuserdatad/UserInterfaceState.xcuserstate matches

Answer 6

I solved this issue by combining nmock's answer with DaNLtR's answer.

So at first i looked for <customFonts key="customFonts"> and there was Montserrat-Light present in it.
But it wasn't neither present in info.plist nor was it added to the project.

The problem vanished once i bundled Montserrat-Light.ttf into the project and added an entry for this font under Fonts provided by this application in info.plist.

So following is the summary of above mentioned solution:

1. Look for your Storyboard or Xib files for any Custom Fonts.
   You'll find them in <customFonts key="customFonts">
2. If there is Actually a Custom Font mentioned, then follow steps 3 and 4
3. Add the font to your Xcode Project.
4. Add an entry to info.plist under Fonts provided by this application.
   This entry should be name of the font file followed by its extension.
5. In case if <customFonts key="customFonts"> doesn't contain any Custom Font (e.g: Helvetica-Neue etc), then try deleting the <customFonts key="customFonts"> entry in Stroyboard or Xib file as stated in DaNLtR's answer

I know its very late to answer but hope this helps someone.
