Maybe you could look at this post, which already has (accepted): https://stackoverflow.com/questions/36486761/make-part-of-a-uilabel-bold-in-swift
Please tell me if that helps!
This was the accepted answer - if you would want it:
You will want to use attributedString which allows you to style parts of a string etc. This can be done like this by having two styles, one normal, one bold, and then attaching them together:

let boldText = "Filter:" let attrs = [NSAttributedString.Key.font : UIFont.boldSystemFont(ofSize: 15)] let attributedString = NSMutableAttributedString(string:boldText, attributes:attrs) let normalText = "Hi am normal" let normalString = NSMutableAttributedString(string:normalText) attributedString.append(normalString)
When you want to assign it to a label:
label.attributedText = attributedString

You will want to use `attributedString` which allows you to style parts of a string etc. This can be done like this by having two styles, one normal, one bold, and then attaching them together:
