How can I change a SwiftUI Color to UIColor?

Question

I'm trying to change a SwiftUI Color to an instance of UIColor.

I can easily get the RGBA from the UIColor, but I don't know how to get the "Color" instance to return the corresponding RGB and opacity values.

@EnvironmentObject var colorStore: ColorStore  init() {     let red =     //get red value from colorStore.primaryThemeColor     let green = //get green value from colorStore.primaryThemeColor     let blue =   //get blue value from colorStore.primaryThemeColor     let alpha = //get alpha value from colorStore.primaryThemeColor          let color = UIColor(red: red, green: green, blue: blue, alpha: alpha)     UINavigationBar.appearance().tintColor = color } 

...or maybe there is a better way to accomplish what I am looking for?

Answer 1

SwiftUI 2.0

There is a new initializer that takes a Color and returns a UIColor for iOS or NSColor for macOS now. So:

iOS

UIColor(Color.red) 

---

macOS

NSColor(Color.red) 

---

Core Graphics

UIColor(Color.red).cgColor /* For iOS */ NSColor(Color.red).cgColor /* For macOS */
