Apple TestFlight
Apple is now rolling Public Links for developers, allowing them to more easily get valuable feedback on their apps before releasing them on the App Store for iPhone, iPad, and Apple TV. Developers can simply enable a public link for their app in App Store Connect that leads to an invitation to test in TestFlight. Share the link to let anyone discover the beta version of your app.
