NSURL getResourceValue in swift

Question

Having trouble figuring out how to make the following call in swift:

var anyError: NSError? = nil
var rsrc: NSNumber? = nil
var success = url.getResourceValue(&a         


        

Answer 1

You need to make rsrc an optional AnyObject and pass it by reference like so:

var anyError: NSError?
var rsrc: AnyObject?
var success = url.getResourceValue(&rsrc, forKey:NSURLIsUbiquitousItemKey, error:&anyError)

Note: You do not need to initialize Optionals to nil, they are set to nil by default.

If you then want to check if the value is an NSNumber you can then do a conversion:

if let number = rsrc as? NSNumber {
    // use number
}
