how to append Attributed Text String with Attributed String in Swift

Question

I want to append an Attributed Text with another Attributed Text in Swift. Please provide any sample code for appending operation of two attributed String in Swift.

Answer 1

@glace's answer, modified to avoid empty NSMutableAttributedString declaration. Valid in Swift 3.1:

let yourAttributes = [NSForegroundColorAttributeName: UIColor.blackColor(), NSFontAttributeName: UIFont.systemFontOfSize(15)]
let yourOtherAttributes = [NSForegroundColorAttributeName: UIColor.redColor(), NSFontAttributeName: UIFont.systemFontOfSize(25)]

let partOne = NSMutableAttributedString(string: "This is an example ", attributes: yourAttributes)
let partTwo = NSMutableAttributedString(string: "for the combination of Attributed String!", attributes: yourOtherAttributes)

partOne.append(partTwo)

partOne is then your final string with all the attributes. No intermediate "combiner" necessary.

Swift 4

let yourAttributes: [NSAttributedString.Key: Any] = [.foregroundColor: UIColor.black, .font: UIFont.systemFont(ofSize: 15)]
let yourOtherAttributes: [NSAttributedString.Key: Any] = [.foregroundColor: UIColor.red, .font: UIFont.systemFont(ofSize: 25)]

let partOne = NSMutableAttributedString(string: "This is an example ", attributes: yourAttributes)
let partTwo = NSMutableAttributedString(string: "for the combination of Attributed String!", attributes: yourOtherAttributes)

partOne.append(partTwo)
