What this error means
The app, or a plugin in it, can use the camera, photos, location or similar, and Info.plist doesn’t say why. Apple requires a sentence for each of those permissions.
Why it happens
A plugin, or the app, references a protected API such as the camera, and Info.plist has no sentence explaining why. App Store Connect blocks the upload until that key exists.
The message tools print
ITMS-90683: Missing purpose string in Info.plist - The Info.plist file for the "App.app" bundle should contain a NSCameraUsageDescription key with a user-facing purpose string explaining clearly and completely why your app needs the data.How to fix it
- Add the key named in the error (NSCameraUsageDescription, for example) to ios/App/App/Info.plist, with a sentence saying what the app does with it.
- Write it for people: “Harbor uses the camera to scan your boat’s registration.”
- If no feature needs it, remove the plugin that triggers it.
