如何在Xcode中将SFPro字体用于部署目标9.3？

Question

Xcode doesn't come with SFPro by default if we set deployment target as 9.3. The system font is SF. I am doubtful if loading SFPro font manually will work even if I have not set deployment target as 11.

You can download the fonts here: https://developer.apple.com/fonts/

Add the font files to your project and declare them in Project Info settings with Fonts provided by application :

Then use the font with code like this (for example):

    if let customFont = UIFont(name: "SFProDisplay-Regular", size: 32) {
        theLabel.font = customFont
    }

To find the actual names of the fonts, you can use this code:

    for family in UIFont.familyNames {

        let sName: String = family as String
        print("family: \(sName)")

        for name in UIFont.fontNames(forFamilyName: sName) {
            print("name: \(name as String)")
        }
    }
