My app icon is not displayed correctly on iOS. But my app icons are in AppIcon.appiconset

Kim Strasser 1,036

I have added my app icons on my iMac to my iOS project in Assets.xcassets-->AppIcon.appiconset. After that I copied my iOS project to my Windows 11 laptop and then I paired Visual Studio with my iMac to debug the iOS project on my iPad. But the problem is that my app icon is not displayed. Another app icon is displayed instead.In addition, I can see my 16 app icons when I click in my iOS project on Asset Catalogs-->Assets-->AppIcon.

In addition, I get this in the output window in VS:

C:\Program Files\dotnet\packs\Microsoft.iOS.Sdk\17.2.8053\tools\msbuild\iOS\Xamarin.Shared.targets(885,3): warning : The app icon set "AppIcon" has 16 unassigned children.

Why is my app icon not displayed on my iPad? I use Visual Studio version 17.10.2.

May I ask what .NET version and iOS version do you use?

My iOS project uses .NET 8.0 and target OS version 17.2 and on my iPad I use iPadOS 17.5.1.

You said Another app icon is dislayed. Is this another app icon you set before? Then you may try deleting your app, clean and rebuild your project.

Also, you may check the content of Contents.json to see if the file name registered under Contents.json matches the actual image's filename. The Contents.json is placed under the ProjectDir/Assets.xcassets/AppIcon.appiconset/on your Windows. Besides, if the Contents.json is correct, you may also try manually resetting the AppIcon using Visual Studio on Windows. Don't forget to clean and rebuild your project.

No, it´s the default app icon that is displayed. I think that the default app icon is always displayed when no other app icon has been set.

I can see my 16 app icon images in the folder ProjectDir/Assets.xcassets/AppIcon.appiconset/.

I have opened Contents.json with the Editor on Windows:

{ "images": [], "properties": {}, "info": { "version": 1, "author": "xcode" } }

Is something wrong with my Contents.json?

Is there anything like this in Contents.json file?

"images": [ { "scale" : "1x", "size" : "20X20", "idiom" : "ipad", "filename": MyIconName20.png,

Besides, in Visual Studio for Windows, you could click Asset Catalogs->Assets->AppIcon and reset the right sized icon images by clicking the meatballs menu at the top-right of each icon.

I have tried to click on the meatballs menu at the top-right of each icon. I have added the same 16 icons but the Contents.json file didn´t changed. The images were not added to the file.

I have a copy of my iOS project on my iMac and there I opened my Contents.json file and I copied everything from this file to my Contents.json file on my Windows laptop and now my icon gets displayed on my iPad.

For example:

{ "images" : [ { "filename" : "40.png", "idiom" : "universal", "platform" : "ios", "scale" : "2x", "size" : "20x20" },
