I have been investigating a recent breakage where apps being installed via Testflight are crashing on launch with no helpful crash reports, or even console-accessible logging. More detail: The app launches just fine on iPadOS 18 beta (ipad) but the same build doesn't work on iPadOS 17.6.1
At my wit's end, I checked the entire build environment - was I using XCode beta still somewhere?
Well, in the XCode Cloud workflow, I had selected "Release" for the latest released version of XCode. And MUCH to my surprise, I see that XCode 16 RC is selected. Why? That's not released yet...
Anyway, this is just a friendly PSA to check your XCode Cloud workflows if you choose "release" when new XCode releases are upcoming... or peg your XCode Cloud environment versions.
And I still don't have an explanation why Testflight XCode 16 RC is producing builds that crash on iPadOS 17.6.1 (for us) but not the latest iPadOS 18 public beta...
