Generatin random color in SwiftUI & UIKit

RandomColor.swift

#if canImport(UIKit)

import UIKit
extension UIColor {
    static var random: UIColor {
        return UIColor(
            red: .random(in: 0...1),
            green: .random(in: 0...1),
            blue: .random(in: 0...1)
        )
    }
}

#elseif canImport(SwiftUI)
import SwiftUI

extension Color {
    static var random: Color {
        return Color(
            red: .random(in: 0...1),
            green: .random(in: 0...1),
            blue: .random(in: 0...1)
        )
    }
}
  
#else
// all other platforms – use a custom color object
#endif

Generating random color in UIKit & SwiftUI

Very clever. Thanks.

In a Swift 5.5 Playground released by Apple (“Recognizing Gestures”), the extension for SwiftUI’s Color gives random() as a func:

extension Color {
    static func random() -> Color {
        return Color(red: Double.random(in: 0...1), green: Double.random(in: 0...1), blue: Double.random(in: 0...1))
    }
}

I wonder if there are any semantic differences in behavior, or if it’s purely the syntactic difference of whether you use Color.random or Color.random()?

@treyharris AFAIK no difference in particular
