In Swift, how can I change an attribute of part of a string?

Question

I am trying to display a score with some text. The score is displayed in the middle of a sentence, and I want the font to be bigger for the score than the rest of the text.

My code is as follows:

let fontSizeAttribute = [NSAttributedStringKey.font: UIFont.systemFont(ofSize: 43)]
let myString = String(describing: Int(finalScore!.rounded(toPlaces: 0)))
let attributedString = NSAttributedString(string: myString, attributes: fontSizeAttribute)
scoreLabel.text = "Your score is \(attributedString)%, which is much higher than most people."

I can't see anything wrong with this implementation, but when I run it, it says, "Your score is 9{ NSFont = "UITCFont: 0x7f815...

I feel like I'm doing something stupid, but can't figure out what it is. Any help would be appreciated!

You should be setting your label attributedtext instead of your late text property developer.apple.com/documentation/uikit/uilabel/… — Leo Dabus

Please check :

let fontSizeAttribute = [NSAttributedStringKey.font: UIFont.systemFont(ofSize: 43)]
let myString = String(describing: Int(finalScore!.rounded(toPlaces: 0)))

let partOne = NSMutableAttributedString(string: "Your ")
let partTwo = NSMutableAttributedString(string: myString, attributes: fontSizeAttribute)
let partThree = NSMutableAttributedString(string: "%, which is much higher than most people.")

let attributedString = NSMutableAttributedString()

attributedString.append(partOne)
attributedString.append(partTwo)
attributedString.append(partThree)

scoreLabel.attributedText = attributedString

Wow. I tried following the links that were posted above, and they did not solve the problem. I spent hours trying to figure this out and eventually discovered the .attributedText function. So I ended up doing EXACTLY what you said here, and then when I checked back to answer my own question, I found your answer. Thanks anyway! I accepted the answer.
