How to use addAttribute in Swift

Question

I am trying to add links to UITextViews, so I follow the code for this post . Relevant Objective-C Code

NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc] initWithString:@"This is an example by @marcelofabri_"]; [attributedString addAttribute:NSLinkAttributeName value:@"username://marcelofabri_" range:[[attributedString string] rangeOfString:@"@marcelofabri_"]]; 

But when I try it in Swift 2 as

 var attributedString = NSMutableAttributedString(string: "This is an example by @marcelofabri_") attributedString.addAttribute(NSLinkAttributeName, value: "username://marcelofabri_", range: attributedString.string.rangeOfString("/marcelofabri_")) 

I get an error

Cannot call 'addAttribute' using argument list of type '(String, value: String, range: Range?)'

What do I need to change to make this work?

Answer 1

Try using NSString to search for a range instead of a Swift String :

 var attributedString = NSMutableAttributedString(string: "This is an example by @marcelofabri_") attributedString.addAttribute(NSLinkAttributeName, value: "username://marcelofabri_", range: (attributedString.string as NSString).rangeOfString("/marcelofabri_")) 

Answer 2

Instead, you use Range, not NSRange. Take a look:

NSRange of Swift Range?
