In Xcode, is there a way to disable the timestamps that appear in the debugger console when calling NSLog?

NSLog() is what is doing that, not the debugger console.

The easiest way to avoid it is to not use NSLog at all. You could use fprintf(), but that is a pain in that it doesn’t support %@ format types.

I generally write a function for this:

void MyLog(NSString *format, ...) {
    va_list args;
    va_start(args, format);
    NSString *formattedString = [[NSString alloc] initWithFormat: format
                                                  arguments: args];
    va_end(args);
    [[NSFileHandle fileHandleWithStandardOutput]
        writeData: [formattedString dataUsingEncoding: NSNEXTSTEPStringEncoding]];

}

Obviously, modify it to add a newline or use a shorter prefix, etc…
