Apple recommends testing on all target versions of iOS before distributing an app.We are able to test with iOS 8, 9, & 10 on simulators, but no longer have an iPhone with iOS 8 running on it.We have asked Apple Business Support for help finding an iPhone with iOS 8 running on it or help downgrading an iPhone to iOS 8.What is the Apple recommended way to be able to test on an iPhone with iOS 8 other than searching used iPhone marketplaces for an old iPhone running iOS 8 (i.e. never upgraded).Since testing on device is recommended, there must be a solution for helping developers do that, correct?
