How to use Bold & Non-Bold Text In A Single UILabel in iOS/iPhone?

To use a Bold and a regular/Non-Bold text in a single UILabel, we can either use a storyboard editor to achieve the same, or we can do it programmatically. Let’s see both of them.

Method One − Editing with Storyboard

• Select the label you want to edit, go to it’s attribute inspector.

• From the first option Text, select Attributes instead of plain.

• Write the following text in the label “Bold Regular”

• Double Click on Bold to select it, and then right click on it to see more options.

• Select font > Bold from that option. It should do the task.

Method Two − Programmatically Achieving the result.

Add the following code inside you View Controller’s View did load method.

override func viewDidLoad() {
   super.viewDidLoad()
   let boldAttribute = [
      NSAttributedString.Key.font: UIFont(name: "HelveticaNeue-Bold", size: 18.0)!
   ]
   let regularAttribute = [
      NSAttributedString.Key.font: UIFont(name: "HelveticaNeue-Light", size: 18.0)!
   ]
   let boldText = NSAttributedString(string: "Bold", attributes: boldAttribute)
   let regularText = NSAttributedString(string: " regular", attributes: regularAttribute)
   let newString = NSMutableAttributedString()
   newString.append(boldText)
   newString.append(regularText)
   lbl.attributedText = newString
}

This code can be converted to function or extensions as per requirement. When we run with any of the above-mentioned methods the same result is produced as shown below.
