How to use addAttribute and NSRANGE in swift 3

Question

Hi, I am trying to use addAttribute in Swift3.

I want to set bold only IDNAME.

Here is what I am trying to do.

 let boldUsername = NSMutableAttributedString(string: "IDNAME hi nice 2 meet you :D #HELLOW") // boldUsername.addAttribute(NSFontAttributeName, value: UIFont(name: "SFUIText-Bold", size: 14)!, range: (boldUsername.string as NSString).range(of: " ")) boldUsername.addAttribute(NSFontAttributeName, value: UIFont(name: "SFUIText-Bold", size: 14)!, range: NSRange(location: 0, length: 5)) 

How do I get the IDNAME ie index every time?

-> Is there a way to split the space and get the index?

You need to do something like this.

 let personName = "Black" let wholeStr = "\(personName) hi nice 2 meet you :D #HELLOW" let boldUsername = NSMutableAttributedString(string: wholeStr) boldUsername.addAttribute(NSFontAttributeName, value: UIFont(name: "SFUIText-Bold", size: 14)!, range: (wholeStr as NSString).range(of: personName))
