TestFlight
A waiting room for your iPhone app, where invited testers try it before the public sees it.
Like handing out a few spare keys before opening your shop. TestFlight lets you share an iPhone or iPad app with invited testers before it is in the App Store.
It helps find bugs on real devices, gather feedback, and see crash reports, without a public launch. Testers install Apple’s TestFlight app, then your build appears there.
You upload a build from Xcode to App Store Connect, write notes, pick who can test by email or a public link, then wait for Apple’s quick review before it goes live.
