Dynamic sizing fonts based on phone screen

I am interested in adjusting the size of the fonts I use dynamically based on the display device. The app is configured to only allow portrait-up display.

struct DisplayFonts {

    static let NavBarTitleFont = UIFont.init(name: "Montserrat-Bold", size: 20.0*fontSizeMultipler) //error 

    private var fontSizeMultipler: CGFloat {
        get {
            let screenSize = UIScreen.main.bounds
            let screenWidth: CGFloat = screenSize.width
            let templateScreenWidth: CGFloat = 375.0

            return screenWidth / templateScreenWidth

        }
    }
}

As noted in the comments, I get the error Cannot use instance member fontSizeMultipler. I was wondering if there is another way to go about using my current struct so the font size could be updated by the screen size? Thaks!

This error is completely clear. You are using "fontSizeMultipler" to calculate a value for a property that is defined "static" so you need to define "fontSizeMultipler" as static too

You should declare you fontSizeMultipler variable as static also:

private static var fontSizeMultipler: CGFloat

you just did a minor Mistake:

struct DisplayFonts {

    static let NavBarTitleFont = UIFont.init(name: "Montserrat-Bold", size: 20.0*fontSizeMultipler)

    private static var fontSizeMultipler: CGFloat {
        get {
            let screenSize = UIScreen.main.bounds
            let screenWidth: CGFloat = screenSize.width
            let templateScreenWidth: CGFloat = 375.0

            return screenWidth / templateScreenWidth

        }
    }
}

See how i changed the the var fontSizeMultipler to static, now both Variables are on the same visibility level, now it should work.
