I am trying to submit my iOS app and I am getting this error:

Your iOS app icon is missing or is an invalid format. The icon must be a 1024x1024 PNG image with no transparency.
Please check your icon image and icon configuration in app.json.

I am using eas build, and eas build.

Checked:

  1. Icon is not transparent
  2. It is 1024x1024
  3. Format is .png
  4. Icon is showing in Expo go
  5. It's configured in app.json like: "expo": { ... "icon": "./assets/icon.png",
  6. the icon is in the right folder
  7. since I am using expo prebuild, I made sure that the icon is also in ios/app/Images.xcassets\AppIcon.appiconset
  8. I have same icon with other names like: AppIcon.png which is the default name by ios, and AppIcon1024x1024.png which matches the name in offical Expo repo
  9. I added <key>CFBundleIconName</key> <string>AppIcon</string> to ios/app/info.Plist

Possible causes?

  1. I am using expo prebuild. However, when if I delete ios folder and try to generate it again using expo prebuild, it DOES NOT generate. not sure why. the only reason why I do have ios folder is because I started a new expo project using expo init --template bare-minimum. I have tried everything to get ``iosfolder generated but no success. **BUT**, when I edited files in the folder like addingCFBundleVersion 19andPRODUCT_BUNDLE_IDENTIFIER = com.lab.app;` and it did actually reflect on the build.

  2. My app name includes - like I have in package.json: "name": "app-name". But when I created it using expo init --template bare-minimum, it removed the - so folders in ios are named: appname & `appname.xcodeproj.

I had a similar issue, but also setting the path to the icon i app.config.js (not only in app.json) made me able to create a build that I could later submit using "eas submit -p ios".

app.config.js:

export default {
  icon: "./app/assets/logo.png",
  // Other config...
};

  • app.config.js overrides app.json completely. In order to have both and still honor app.json settings, you need to import them in app.config.ts by returning a function, not an object, like `module.exports = config => ({...config, newValue: ...});` If you do that you should be able to only specify icon in app.json (the static config) not app.config.ts (the dynamic config). This is not very clear from the docs – Freewalker May 31 '23 at 21:29

so expo prebuild for ios apps doesn't even work on windows

expo prebuild -p ios 

Ejecting is unsupported locally on windows, use eas build instead
⚠️  Skipping generating the iOS native project files. Run expo eject again from macOS or Linux to generate the iOS project.
