objective-c not catching exception in try/catch block

Question

I have this statement inside a try/catch block, but the exception is never caught. In fact, any exception thrown is never caught. Can anyone help me?

Is there any setting disabled in the xcode project that disables catching exceptions?

NSString *test = @"test";
unichar a;
int index = 5;

@try {
    a = [test characterAtIndex:index];
}
@catch (NSException *exception) {
    NSLog(@"%@", exception.reason);
}
@finally {
    NSLog(@"Char at index %d cannot be found", index);
    NSLog(@"Max index is: %lu", [test length]-1);
}

Answer 1

In my case, there is a Other Liker Flag -Wl,-no_compact_unwind in the build setting of my project.

I remove it, then the problem be solved.

Answer 2

You can go to build settings -> Enable Objective-C Exceptions

It should solve the problem.

Answer 3

Use the physical device instead of the simulator.
