My challenge is that I don't know what this means or how to convert
this into actual code. So I have to keep guessing which surely
can't be the preferred way to learn!

Along with what others have said, for this specific task you would
probably want to use:
-(NSString*) substringWithRange:(NSRange) range;
instead. It's fairly rare to break down strings into individual
characters.
So with your newly learned knowledge of Objective-C, you could now
write a

Can anyone explain how I can 'decode' the usage information shown in
the documentation into real code? Not just for this example, but in
general.
OK, let's do this one par
Hi Phil,
You're right: the documentation can take some getting used to.
Here are some tips:
When you see a method declared with a "-" out in front, such as:
- (NSString *) substringWithRange:(NSRange)range;
That means that you can only use that method on an instance of the
class. For example:
N
You're not having a problem reading the docs. You're having a problem with
your basic understanding of Objective-C. There's nothing to "convert" and
what you're reading is "actual code". I'd recommend taking a step back and
doing some reading before you go any further.

Hi all.
As a relative newbie I'm eager to learn but my biggest stumbling block
is understanding that the XCode's Help>Documentation actually means;
can someone guide me?
For example, if I want to put a substring of a larger string (eg.
"ertyu" from "qwertyuiop") into a second field, I sea
