I created a new project in UE 5.7.1 on windows 11 and remote build on a mac running mac os 26 and xcode 26.1.1, everything looks fine, not even a single error appeared. And I got an ipa file on my windows before I happily upload it to app store connect to test but only to find out this:

No matter how many times I rebuild with different setting, the same invalid ipa is given. I analyzed into the ipa, everything look fine though. Any idea?

Besides, I tried to quick launch on my iPhone xs, but UE 5.7.1 just don’t show anything when I plug in my iPhone, no matter how many times I tried.

Hi Stephen,  
Are you able to install and launch the generated IPA from the IPhonePackager desktop app located under Engine\Binaries\DotNET\IOS?  
Best regards.

I created a fake proj with xcode before I replaced archive binary with the binary in ue generated ipa, and uploaded with Xcode instead of transporter, it worked!
