Our team built a few technical demo apps and want to send them to third party for showcasing.
For android we can simply send the apks.
But for iOS it seems the only choice is TestFlight external test, so we don't need to collecting device UUID/apple account.
We submitted the app to TestFlight. But Apple rejected our apps from beta testing according to App Store guidelines, yet we are not intended to release the apps to App Store.
Are there any other options to openly test our half-finish apps? (without the need to collect device UUID/apple account)
