My process to have the same AIA for Android and iOS is this:
- I develop the source AIA in the Android AI2 Server and test it whit the MIT AI2 Companion.
- I built the APK object and download it to my Smartphone Android. For to do a real test.
- I export the AIA in this Android AI2 Server.
- I import the before AIA in the iOS AI2 Server.
- I do special adjustments in the original AI2 for the platform iOS issues (basicaly dimensions of layouts that I need put as fix and not automatic). That means I go to the Step 1 until all is right in iOS and Android.
- I buil the IPA files for iOS to do a real test whit my iPhone
- I test the app in my iPhone by download the IPA object (Ad Hoc). My iPhone is a Betatest equipment prior approved by Apple where I can download the app to do a real test.
- After all is right in both platforms I built the AAB object and I upload it to the Android Play Store for Google review and final aprobation and publishing.
- And finally I upload the iOS build direct to the Apple App Store in the iOS AI2 Server for Apple review and final aprobation and publishing.
Normally the Google review lasts more or less 8 hours, for Apple the review lasts 1 day. If you have rejections you must replay in both platforms with suitable correcctions.
Note: I develop all the steps only with Windows - Firefox Browser for to have a best compability.
