TestFlight Usage

 https://apps.apple.com/us/app/testflight/

Test Flight used for BETA testing of your app before App Store submission.

It will be uploaded from Xcode using the Distribution Profile. It will go Apple review, turn around time will take min 2days for First Version upload, subsequent build no. increase will be auto approved sooner. Any further increase in version will take 2 days for sure.

 (E.g) 1. 0 (1) - 2days

1.0 (3), (4), .. will be quicker

1.1 / 2.0 … will take time for review.

Any uploaded Builds will go auto expire for Build Shared in the Test Flight 90days (as on). But caveat is, those who downloaded and using the build will not break, it will still work without issue. Any new builds posted will give Notifications to the user, but not force to upgrade from TestFlight.

If we are plan to force upgrade, we need to right the logic in the Service on launch and alert the user for upgrade, no other choice with Expiry build with test flight.

Above are experience with my project.

Building multiple iPhone targets in XCode

This is more helpful now for creating multiple version of same product by only skin change or even lighter change in functionality.

Other case, if we are going to release 'lite' and 'full' version of the same product. We can customize our targets with the required resource based on the release type.

iOS App Store Package (.ipa) option got disabled after archive

This happens when your build produces more than a single target: say, an app and a library....
