UIFont - how to get system thin font

UIFont has methods to get regular font (systemFontOfSize) or bold font (boldSystemFontOfSize), but how to get a "thin system font" available through storyboard?

Passing "system-thin" to UIFont Contructor doesn't work, this constructor only works for non system fonts.

Solution

  • You can use system font thin weight:

    UIFont.systemFont(ofSize: 34, weight: UIFontWeightThin)

    List of available weights for San Francisco:

    UIFontWeightUltraLight
UIFontWeightThin
UIFontWeightLight
UIFontWeightRegular
UIFontWeightMedium
UIFontWeightSemibold
UIFontWeightBold
UIFontWeightHeavy
UIFontWeightBlack
