[ios] Error ITMS-90717: "Invalid App Store Icon"

When I tried to submit an App to Itunes Connect I got the following error.

iTunes Store Operation Failed

Error ITMS-90717: "Invalid App Store Icon. The App Store Icon in the asset catalog in 'YourApp.app' can't be transparent nor contain an alpha channel."

I made sure that I submitted a file with no transparency. So the error persisted in submission to iTunes Connect.

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.

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

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 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 export option (in the File menu) , then the option to save it without “alpha” comes up

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.

If you're facing this issue in Flutter then you're good to go here.

Issue is indicating you're using .png as image asset. Just try to replace .png to .jpg and build your project again..!!

Use this plugin. - flutter_launcher_icons: ^0.8.1

flutter_icons:
  android: "ic_launcher"
  image_path_android: "assets/logo_panda.jpg"
  ios: true
  image_path_ios: "assets/logo_panda.jpg"

Make sure you're using the .jpg image extension as the image path.

This help me to upload the app to the App Store.

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

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 "{}" \;

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 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.

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

Solved in Catalina

1. copy to desktop
2. open image in PREVIEW APP.
3. File -> Duplicate Close the first opened preview
4. after try to close the second duplicated image, then it will prompt to save there you will available to untick AlPHA

look into my screenshot

Remove the alpha channel using this command in the folder 'Images.xcassets', this command will remove all alpha channels from your .png files and it will put the background color to white

for i in `ls *.png`; do convert $i -background white -alpha remove -alpha off $i; done

I also shell script using ffmpeg to resize images without alphachannel. It worked for png format fine.

# Export ios app icons by ffmpeg scale command
# usage: sh export_ios_icons.sh {path_to_your_img}
# example: sh export_ios_icons.sh ./app_icon.png

# sizes of images
# you can get other size images by editing thisarray
size=(20 40 60 29 58 87 80 120 180 76 152 167 1024)
for i in "${size[@]}"
do
   : 
    ffmpeg -i $1 -vf scale=$i:$i output_$ix$i.png
done

If you don't have a mac, on windows you can open Paint and save as PNG with correct dimensions 1024x1024

Even the .png file without transparency the error persists.

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

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.

Dumb mistake from my part, didn't archive the app after removing alpha. Just kept submitting my old archived app and finding same alpha/transparency error. Hope it helps someone.
