What is the type of ‘destURL’? URL or NSURL? It sounds like it’s NSURL. The function signature in class NSURL is: > func setResourceValues([URLResourceKey : Any]) whereas the function signature in class URL is: > func setResourceValues(_ values: URLResourceValues) So, you either need to change destURL to be a URL, or use the NSURL API that takes a dictionary. Note that URL is not just a cosmetic renaming of NSURL in Swift 3, but a whole new type that wraps a NSURL object. Both types are accessible, though you’re going to have the best Swift 3 experience if you switch to URL — and its altered API and semantics. Regarding Any vs. AnyObject as the dictionary value, the error message I get (in Xcode 8.1 beta, with the above code) is: > Cannot convert value of type 'URLResourceValues' to expected argument > type '[URLResourceKey : Any]’ So, you’re either not compiling against the 10.12 SDK (which I think should be impossible), or you’re compiling as Swift 2.3, or Xcode at least thinks you are. _______________________________________________ Cocoa-dev mailing list ([email protected]) Please do not post admin requests or moderator comments to the list.
