Xcode problems with debug mode and breakpoints

I have such a situation: when I'm running my project with breakpoints, compiler goes to the first one and stops program as usual until I'm press a next step button. But when I'm going next - th开发者_运维问答ere is no reaction from his side, then I clicking 2-3 times 'next step'(Step into) button - after that he run program to the end and have no reaction.

I tried to do: Build->Clear All Targets - but it gives no results. Tried to restart computer - the same effect.

The debugger log is as follows:

After further review, it looks like this code was the reason:

NSArray *path = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [path objectAtIndex: 0];
    NSString *fname = [documentsDirectory stringByAppendingPathComponent: @"phoneBook.sqlite3"];

This code takes current directory of the executable, and then I create my database file there. first time all good, second - bad. What could be the cause of this, and how can I fix it?

Do a Cmd + Opt + B to show all your breakpoints. Remove all breakpoints. Now clear your Simulator via iPhone Simulator -> Reset Content and Settings and give it another try.

Check your program log. It sounds like the app has crashed.
