Setting UILabel text to bold

Question

How do you set the text for a UILabel to bold in Swift programmatically? My code so far:

    var label = UILabel(frame:theFrame)
    label.text = "Foo"

Look at the docs for `UILabel`. Notice the `font` property. – rmaddy Jul 29 '14 at 22:10 — rmaddy, Jul 29 '14 at 22:10

Use font property of UILabel:

label.font = UIFont(name:"HelveticaNeue-Bold", size: 16.0)

or use default system font to bold text:

label.font = UIFont.boldSystemFont(ofSize: 16.0)

Use attributed string:

// Define attributes
let labelFont = UIFont(name: "HelveticaNeue-Bold", size: 18)
let attributes :Dictionary = [NSFontAttributeName : labelFont]

// Create attributed string
var attrString = NSAttributedString(string: "Foo", attributes:attributes)
label.attributedText = attrString

You need to define attributes.

Using attributed string you can mix colors, sizes, fonts etc within one text

Technically correct, but slightly overkill. – nhgrif Jul 29 '14 at 23:09

To expand on nhgrif's comment. NSAttributedString makes sense in this case - http://stackoverflow.com/questions/28496093/making-text-bold-using-attributed-string-in-swift – Nitin Nain Mar 20 '16 at 17:28
