XCode crash

[keepyounger]

When I debug my APP like this

XCode do crash!

Additional: ConsoleTextView is not empty. When I debug my APP with breakpoint by Step over, Xcode do crash!

Application Specific Information:
ProductBuildVersion: 6C131e
UNCAUGHT EXCEPTION (NSRangeException): *** -[__NSCFString substringFromIndex:]: Index 240 out of bounds; string length 180

During debugging doesn't make any sense... Do you have a log or something happening while stepping?
Any output (when LLog isn't running)?

I faced the same issue when pasting to the console, but didn't fix it yet.

Thanks for report, though!

If I modify the code like this. Xcode will not crash.

But the console ...

Maybe Xcode doesn't know the length of string in the console has changed. Because you changed it directly.

I tracked the issue down, didn't finish my fix yet, but I'm working on it! Please be patient and stay tuned :)

I did a bit research on this issue. There is one EXTREMELY strange thing happening.
For me this issue happens when I try to write comments in the log.

I put a log right before the line you commented out.
After adding many checks to ensure I'm not accessing ranges that exceed the content I'm still getting a crash.

The log right before the replacement does not appear, but I'm getting the following exception:

I definitely don't understand what's happening here, because when commenting out the replacement call, I'm not getting the exception, otherwise I'm not getting the log, so I believe my call doesn't even happen, but it still produces a crash.

Can someone please help here?
