You can send me the Certificate and Provision for Distribution, BundleID, and the latest build number in Testflight, and a certain project configured for AR, in UE5.1 from the Launcher with DefferedShading enabled, I can compile it for you and send the .ipa file, however you need One thing to keep in mind, after April 25th Testflight will be able to upload applications with IOS version 16 or higher. And to compile under IOS 16 in UE5.1, you must use XCode version 14 or higher. And for Xcode 14, you need to install Ventura, and by the way, this problem is not from EpicGames, but from Apple, on the Apple forums people have been waiting for a fix for this problem for a year, apparently that’s why Epic Games constantly transfers the fix of this problem from version to version, because it’s too low-level problem in Metal itself. So I don’t think we should expect this issue to be fixed anytime soon, even if Apple fixes this issue they will probably fix it in the next release of Metal and then have to wait for Epic Games to update Metal in the next release of Unreal Engine. But I may be wrong.
My configuration
IMac 2015 i5
macOS Monterey 12.6.4
XCode 13.4.1
Metal 2.4
iOS 15
Unreal Engine 5.1.1
I tested several completely different projects, and everything works, I’m sure that if you set up your system similarly to mine, everything will work for you too, though, as I already wrote above, I’m not sure that this makes sense, only if your project is already ready and you just need to upload it with no further updates soon as this will only work until April 25th.
