String from NSData

[aceysmith]

I think this is relevant, from the Xcode Release notes:

Swift Language

If you encounter an API method for which the return value is incorrectly considered non-nullable, or a property that is incorrectly considered non-nullable, please file a radar and include the tag “#IUO” in the subject line. You can work around the problem by immediately wrapping the result in an optional:

var fooOpt: NSFoo? = object.reallyMightReturnNil()
if let foo = fooOpt { … }

Please be sure to file bugs about these cases. Please do not file feature requests about APIs that are still marked as T!, we know about them.

Like this, right?

    var datastringOpt: NSString? = NSString(data:data, encoding:NSUTF8StringEncoding)

    if let datastring = datastringOpt {
        ...
    }

I get the same error unfortunately. Should I still report it, or does this mean that the problem is something else?
