I am publishing my application through Xcode for the first time but I got the error below.

enter image description here

Error Message below

Invalid App Store Icon. The App Store Icon in the asset catalog in 'Runner.app' can't be transparent not contain an alpha channel. (ID 92c246d0-1226-4b59-ba5d-791e719c0000)

What I have done

I have double check my Asset folder and App Icon but I don't figure what it wrong with my App Icon. I don't know how to troubleshoot this error, I have check online for a suitable solution but I got nothing. I will appreciate a quick solution because I am indeed stuck .

  • What image format is your app icon? Does it contain transparent pixels? Judging from the screenshot, I'd say they probably do. – Abion47 Jul 27 '23 at 16:31
  • The image format is in png @Abion47 – abeeb ilias Jul 27 '23 at 16:32
  • The error message makes it clear that the image cannot contain transparency of any kind. You will need to edit your image to have an opaque background. – Abion47 Jul 27 '23 at 16:34
  • What do you mean by transparent pixel. How do I know if it contain transparent pixel. Please guide me. I am new to this. @Abion47 – abeeb ilias Jul 27 '23 at 16:35
  • I don't know how to explain that. Transparent pixel means a pixel that is transparent. The alpha channel has a value that is less than the maximum. If you were to overlay the image over another image, you would see the second image under the first. See more: https://en.wikipedia.org/wiki/Transparency_(graphic) – Abion47 Jul 27 '23 at 16:40
  • try to follow this answer: https://stackoverflow.com/a/38256612/4899849. So at the beginning remove alpha channel from your image, save it and then create all iOS assets using online generator like: https://makeappicon.com – Volodymyr Jul 27 '23 at 16:42
  • @Abion47 I understand what you are talking about, Opaque is definitely the opposite of transparency. I will work my image. – abeeb ilias Jul 27 '23 at 17:09
  • @Volodymyr thank you for solution as well. I will put all of your solution in to use and revert back on this channel. – abeeb ilias Jul 27 '23 at 17:13
  • If you put it on a red background, do you have a black square containing your logo on a red surrounding, or do you have red color right up next to the green? – Randal Schwartz Jul 27 '23 at 18:31
  • @Volodymyr the solution you refer me to did not work for me is still error. I edited the image by unchecking the Alpha attribute then save the image, when I view my image the background change to white. Then after I make use of makeappicon.com to generete new icon. but still I got the same error. – abeeb ilias Jul 28 '23 at 11:25
