I would highly recommend using a library for attributed strings. It makes it much easier when you want, for example, one string with four different colors and four different fonts. Here is my favorite. It is called SwiftyAttributes

If you wanted to make a string with four different colors and different fonts using SwiftyAttributes:

let magenta = "Hello ".withAttributes([
    .textColor(.magenta),
    .font(.systemFont(ofSize: 15.0))
    ])
let cyan = "Sir ".withAttributes([
    .textColor(.cyan),
    .font(.boldSystemFont(ofSize: 15.0))
    ])
let green = "Lancelot".withAttributes([
    .textColor(.green),
    .font(.italicSystemFont(ofSize: 15.0))

    ])
let blue = "!".withAttributes([
    .textColor(.blue),
    .font(.preferredFont(forTextStyle: UIFontTextStyle.headline))

    ])
let finalString = magenta + cyan + green + blue

finalString would show as
