Answer 1

Try

[infoLabel setFont:[UIFont fontWithName:@"Arial-BoldMT" size:16]];

It may also be worth checking if the font you're trying to use is available on device

It would be nice to merge this answer and the one below: If you want to retain the system font and make it bold: [infoLabel setFont:[UIFont boldSystemFontOfSize:16]]; – Headmost

Answer 2

If you want to retain the system font and make it bold:

[infoLabel setFont:[UIFont boldSystemFontOfSize:16]];

And if you want to retain the size: [infoLabel setFont:[UIFont boldSystemFontOfSize: infoLabel.font.pointSize]]; – Legwork

Answer 3

Using the GUI in Xcode select the label then go to the Attributes Inspector. One of the options is Font. Click on the font icon (not the up-down arrows). In the popup that appears expand the Font ComboxBox. Under the Bold System section choose Regular.

Answer 4

For swift users this should work:

myLabel.font = UIFont.boldSystemFont(ofSize: 12.0)

or if you'd like to use a different font:

myLabel.font = UIFont(name:"HelveticaNeue-Bold", size: 12.0)

Answer 5

Where possible I would suggest using dynamic font sizes to provide the best possible accessibility to your users.

You can make a label use a system dynamic font and set it to have bold text by doing the following:

 exampleLabel.font = UIFont.preferredFont(forTextStyle: .body, compatibleWith: UITraitCollection(legibilityWeight: .bold))

I tried this just for fun ... didn't work. – Suppositive

Worked for me. That having been said, when I want to use custom fonts/styles in my app, but want it to size dynamically, I often use scaledFont. E.g., UIFontMetrics.default.scaledFont(for: customFont). – Tisatisane

But, fundamentally, I think this answer is correct, that one should almost never use fixed font sizes within an app. Dynamic type is the way to go! – Tisatisane

Answer 6

You can set the stroke with a negative value to make a bold effect if you don't have the bold variation of your custom font. See here:
