How do I include iOS App Icon image within the app itself?

Question

I have standard iOS app, with a standard app icon contained in Assets.

I'd like to display the app icon within the app (using SwiftUI). Note that I am not asking how to set the app icon, or change the icon dynamically. I just want to show the app icon within the app's own Settings view.

It would appear the App Icon asset should just be like any other, and I could include it using the following (note there is no space between App and Icon in the default icon naming),

Image("AppIcon")

I've also tried experimenting with,

Image("[email protected]") // Pick out a specific icon by filename
Image("icon_60pt@3x") // Maybe it assumes it's a .png
Image("icon_60pt") // Maybe it auto picks most appropriate resolution, like UIKit

...but none of these work.

How do I include the apps own icon within the app, without duplicating it as a separate Image Set (which I have tried, and does work.)

Thanks.

Answer 1

The following works if app icon is correctly set for used device (ie. iPhone icons for iPhone, etc.)

Note: sizes of app icons must match exactly!

Tested with Xcode 11.4

Image(uiImage: UIImage(named: "AppIcon") ?? UIImage())

This works:

extension Bundle {
    var iconFileName: String? {
        guard let icons = infoDictionary?["CFBundleIcons"] as? [String: Any],
              let primaryIcon = icons["CFBundlePrimaryIcon"] as? [String: Any],
              let iconFiles = primaryIcon["CFBundleIconFiles"] as? [String],
              let iconFileName = iconFiles.last
        else { return nil }
        return iconFileName
    }
}

struct AppIcon: View {
    var body: some View {
        Bundle.main.iconFileName
            .flatMap { UIImage(named: $0) }
            .map { Image(uiImage: $0) }
    }
}

You can then use this in any view as just:

AppIcon()
