Error ITMS-90717: “Invalid App Store Icon”

Below solution worked for me

1. Click & open the App Store icon (1024*1024) in preview app.
2. Export it by unticking the Alpha channel.
3. Replace the current App Store icon with the newly exported icon image.
4. Validate and upload.

Note: This will not work on Mac OS High Sierra, please try a lower version to export without alpha or use any one of the image editing applications or try out the below alternative solution.

Alternative:(Using Sierra or High Sierra and Ionic)

1. Copy and Paste the App Store icon to the desktop.
2. Open the image. Click File Menu->Duplicate.
3. Save it by unticking the Alpha channel.
4. Replace the current App Store icon with this one.
5. Validate and upload.

I faced the same problem and wasn't able to fix it with the provided solution by Shamsudheen TK. Ionic somehow added transparency to my icons even if the source icon did not have any transparency at all. In the end I was able to resolve it by:

Install imagemagick (MacOS):

brew install imagemagick

Remove alpha channel from all images in resource folder:

find ./resources/ -name "*.png" -exec convert "{}" -alpha off "{}" \;

Here is a solution that have worked for me on High Sierra

1. Open the App Store icon (1024*1024) in Preview app(default OSX image viewer).
2. Click on the File menu from the menu bar and select Export. view screenshot
3. Uncheck Alpha, select where you would like to export the image and click on the Save button. view screenshot
4. Replace the current App Store icon with the newly exported icon image.
5. Validate and upload.

Even the .png file without transparency the error persists.

The solution was to change the .png file to a .jpg file.

If showing this error for ionic3 project when you upload to iTunes Connect, please check this ANSWER

This is my project error when I try to vilidated.

Finally follow this ANSWER, error solved.

An error message itself says:

"Invalid App Store Icon. The App Store Icon in the asset catalog in 'YourApp.app' can't be transparent nor contain an alpha channel."

All app icon must be square without transparency or semi transparent (alpha value != 1.0).

Hint: App icon may have rounded corners. (Share your app icons here)

Here is Apple guidelines for App Icon - Human Interface

Whatever way you try above you need to test it by upload it to app connect like me to make sure it works and save your valuable time

I was able to get around the Mac Sierra OS issue by duplicating the file, dragging the new file onto my desktop, open in preview, then click the exit button, then the option to save it without “alpha” comes up

Use Alpha Channel Remover. It lets you drag icons into the app and it'll remove transparency.

Download it from here: http://alphachannelremover.blogspot.com

Update: this is not my site

I tried several of the things mentioned in this post (besides swapping to a .jpg) with no success. I solved it by opening the file in photoshop and using 'export to web'. Within that process/window is a checkbox for transparency.

I had this problem and it was because my app store icon wasn't explicitly listed in my config.xml. Once I added the line

<icon height="1024" src="www/res/icon/ios/icon-1024.png" width="1024" />,

cordova copied it over correctly without adding an alpha channel.

changed the icon from png format to gpg and everything went well.
