DynamicIcon

Swift API to change application icon without any limit nor having a dialog presented.

This uses Apple private APIs. It did not trigger App Store rejection for me but, do tell it if it does for you.

Install

Recommended

Copy DynamicIcon.swift to your project.

SPM

To add a package dependency to your Xcode project, select File > Add Package and enter this repository's URL (https://github.com/g-cqd/DynamicIcon).

Example

First, create AppIcon iconsets in your assets and use their names in the code below. You can reset the icon to the original one by passing nil as argument of the method.

import SwiftUI
import DynamicIcon

struct ContentView: View {
    
    struct Icons {
        static var blue = "AppIcon1"
        static var red = "AppIcon2"
    }
    
    var body: some View {
        VStack {
            Button("Set Icon to Blue") {
                DynamicIcon.setAlternateIconName(Icons.blue)
            }
            Button("Set Icon to Red") {
                DynamicIcon.setAlternateIconName(Icons.red)
            }
            Button("Reset") {
                DynamicIcon.setAlternateIconName(nil)
            }
        }
    }
}
