Hi, I'm trying to convert the following code snippet to Swift: NSURL* pathURL = [NSURL fileURLWithPath:path]; BOOL success = [pathURL setResourceValue:tags forKey:NSURLTagNamesKey error:&outError]; However, it looks like the equivalent is now blocked in the API definition - in the Xcode 12 Swift API declaration .tagNames (and allValues) are get-only properties of URLResourceValues (according to StackOverflow, they were mutable in the past). extension URL {     func setTagNames(_ tags: [String] ) {         var values = URLResourceValues()         values.tagNames = tags // Error here: Cannot assign to property: tagNames is get-only         try self.setResourceValues( values )     } } How can I set the tagNames? Thanks, Thomas
