Hello,
No the Mac device is plugged in physically, it is paired.
You select Remote Device in the Visual Studio toolbar when publishing the app, right? See the step 2 on the official publishing doc- Publish a .NET MAUI iOS app for App Store distribution - .NET MAUI | Microsoft Learn
Root CA -- Are you talking about this
No, the certificate named Apple Worldwide Developer Relations Certificate Authority
.
Xcode Version: Xcode 15.3 - Build version 15E204a
Xcode 15.3 is not supported yet, you could keep using Xcode15.2. (It's not clear if this is a reason why you cannot publish the app, you could check the above two problems first, and finally troubleshoot the cause.)
Best Regards, Wenyan Zhang
