For installed fonts, use the UIFont initializer to refer to a font by name. For example UIFont.init?(name: String, size: CGFloat) Use the UIFont familyNames property to get the list of installed font families then get the actual installed fonts with fontNames(forFamilyName:)

My understanding is that San Francisco is only licensed for use to write apps for Apple devices (e.g. iPhone, Apple Watch, Macintosh, etc.) Outside of app development, you can create UI mock-ups. Otherwise I believe SF font is not licensed for other purposes, and I think this also includes symbols. I would suggest consulting the Symbols and SF font license terms.

It appears Apple has restricted getting SF font by name in latest OS release. Use System Font APIs instead. NSFont has the following methods (amongst others): systemFont(ofSize:) preferredFont(forTextStyle:options:) Hope this helps. Doug Hill https://github.com/djfitz/SFFontFeatures
