iOS Prebuilt Binaries iOS 16.2

Hi,

I have tried both the latest UE5.4 and 5.5 preview:

When I try to upload iOS app to AppStore/Testflight, it complains the app is built with iOS 16.2, and needs to be iOS 17+.

I am getting desperate, not sure what else to try, any help please.
Do I need to download source and build binaries myself? How come the prebuilt binaries for official UE5.4 do not work with Appstore?

Thanks

I resolved this by adding a blank C++ source file, and it forced a build that was using my Xcode iOS SDK which is iOS 18. Not sure why I needed to do that, the iOS SDK should be updated.
