Changing alternate icon for iPad

Question

I have a problem with changing app's icon on iPad. Everything is working fine on iPhone but on iPad I get this error :

[default] Failed to set preferredIconName to AI-Gorgosaurus for ...:0> error: Error Domain=NSCocoaErrorDomain Code=4 "The file doesn’t exist." UserInfo={NSUnderlyingError=0x600000248a30 {Error Domain=LSApplicationWorkspaceErrorDomain Code=-105 "iconName not found in CFBundleAlternateIcons entry" UserInfo={NSLocalizedDescription=iconName not found in CFBundleAlternateIcons entry}}} App icon failed to due to The file doesn’t exist.

I searched ad found that I need to add ~ipad in CFBundleIconFiles but still get the same error!.

Here is the code:

  func changeIcon(to name: String?) {         //Check if the app supports alternating icons         guard UIApplication.shared.supportsAlternateIcons else {             return;         }          //Change the icon to a specific image with given name         UIApplication.shared.setAlternateIconName(name) { (error) in             //After app icon changed, print our error or success message             if let error = error {                 print("App icon failed to due to \(error.localizedDescription)")             } else {                 print("App icon changed successfully.")             }         }     } 

I just tested on another project and works fine !!! but not on my current project why ?! have you any idea?

Answer 1

Your info.plist is structured incorrectly.

You have:

- CFBundleIcons   - CFBundleAlternateIcons     - Icon Name       - CFBundleIconFiles       - CFBundleIconFiles~ipad 

But it should be:

- CFBundleIcons   - CFBundleAlternateIcons     - Icon Name       - CFBundleIconFiles - CFBundleIcons~ipad   - CFBundleAlternateIcons     - Icon Name      - CFBundleIconFiles 

Basically, once you have it working with iPhone icons, CFBundleIcons, duplicate the entire tree as CFBundleIcons~ipad. The iPad files shouldn't be nested under CFBundleIcons at all.

You're mixing up CFBundleIcons~ipad and CFBundleIconFiles~ipad (which isn't a valid key).

Attempting to give a more re-useable (easy to copy/paste) version of this answer.

1) You need images of the following names and sizes added as regular .png files (no asset catalogues)

.../AppIcon-Dark/iPad-app.png   pixelWidth: 76 .../AppIcon-Dark/[email protected]   pixelWidth: 152 .../AppIcon-Dark/[email protected]   pixelWidth: 167 .../AppIcon-Dark/[email protected]   pixelWidth: 120 .../AppIcon-Dark/[email protected]   pixelWidth: 180 

you can then add/insert the following in your info.plist

<key>CFBundleIcons</key> <dict>     <key>CFBundleAlternateIcons</key>     <dict>         <key>AppIcon-Dark</key>         <dict>             <key>CFBundleIconFiles</key>             <array>                 <string>iPhone-app</string>             </array>         </dict>     </dict>     <key>CFBundlePrimaryIcon</key>     <dict>         <key>CFBundleIconFiles</key>         <array>             <string>AppIcon</string>         </array>     </dict> </dict> <key>CFBundleIcons~ipad</key> <dict>     <key>CFBundleAlternateIcons</key>     <dict>         <key>AppIcon-Dark</key>         <dict>             <key>CFBundleIconFiles</key>             <array>                 <string>iPad-app</string>                 <string>iPad-pro</string>             </array>         </dict>     </dict>     <key>CFBundlePrimaryIcon</key>     <dict>         <key>CFBundleIconFiles</key>         <array>             <string>AppIcon</string>         </array>     </dict> </dict> 

I then set my icon with the following

func updateIcon() {     if #available(iOS 13.0, *) {         let dark = window?.traitCollection.userInterfaceStyle == .dark          let currentIconName = UIApplication.shared.alternateIconName         let desiredIconName:String? = dark ? "AppIcon-Dark" : nil          if currentIconName != desiredIconName {             UIApplication.shared.setAlternateIconName(desiredIconName) {                 (error) in                 print("failed: \(String(describing: error))")             }         }     } }
