macOS String madness Objective C

So even trying to do a simple thing like getting an index of a string is not easy in objective C.

with characterAtIndex I get handed the unicode of the string, so their must be a method to convert the unicode to string.

Were the people who created objective C kind enough to include a method to convert a unicode back to a string, or must I take out the unicode chart and do it all myself?

int hi = [@"hello world" characterAtIndex:1];
textView.text = [NSString stringWithFormat"%d", hi];

Code:

int hi = [@"hello world" characterAtIndex:1];
textView.text = [NSString stringWithFormat:@"%d", hi];

Click to expand...

NSString *helloFirstLetter = [@"Hello" substringWithRange:NSMakeRange(0,1)];

For those who need to do their own low-level processing, and who are willing to handle Unicode complications themselves, we provide access to UTF-16 directly via characterAtIndex: et al., and to other representations with getBytes:… and related methods.

For some reason when I looked at the return value type "unichar" for characterAtIndex I thought it meant it would return unicode .
