iOS Different Font Sizes within Single Size Class for Different Devices

by

Edit: I don’t recommend this anymore. This approach doesn’t scale well when new devices come out. Use a combination of dynamic font sizes and size classes-specific fonts.

Say a new iPhone model comes out, if you are using Auto Layout and Size Classes you don’t have to fix all the constraints manually to make your app compatible with this newer device. However, you can still set the font size of the UILabel using the following code:

if UIScreen.mainScreen().bounds.size.height == 480 {
    // iPhone 4
    label.font = label.font.fontWithSize(20)     
} else if UIScreen.mainScreen().bounds.size.height == 568 {
    // IPhone 5
    label.font = label.font.fontWithSize(20)
} else if UIScreen.mainScreen().bounds.size.width == 375 {
    // iPhone 6
    label.font = label.font.fontWithSize(20)
} else if UIScreen.mainScreen().bounds.size.width == 414 {
    // iPhone 6+
    label.font = label.font.fontWithSize(20)
} else if UIScreen.mainScreen().bounds.size.width == 768 {
    // iPad
    label.font = label.font.fontWithSize(20)
}
