How can you use SFPro font in Xcode for deployment target 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)")
        }
    }
