Our company created .NET MAUI application for ERP purpose. currently it deploying to android and windows as well and those are working fine. we started it from .NET 7 and currently we are using .NET 8 as well. when I trying to build it for iOS I got several issues and I fixed most of the things. but I got issue that cannot find a resource to fix that.

here is description of my environment. I developing using windows pc but building for windows and android was done using CI/CD pipeline now. previously I used to windows PC for build that platforms. for iOS I tried to build using iOS using XCode latest and dotnet 8 for mac arm64 devices and apple m2 MacBook as well. but I cannot directly connect my MacBook and windows pc. there are too much lessons for develop by connecting windows and MacBook. so I tried to build it from MacBook itself. it seems working but I got error below. I need to fix that but I couldn't find any way to fix that.

    Hello,

    To publish an iOS app, you must have a Mac and an Apple Developer Program for creating an App Store distribution provisioning profile.

    1. Create a distribution certificate. For more information, see Create a distribution certificate.
    2. Create an App ID. For more information, see Create an App ID.
    3. Create a provisioning profile. For more information, see Create a provisioning profile.

    For more details, please refer to Publish a .NET MAUI iOS app for App Store distribution - .NET MAUI | Microsoft Learn (You can publish the app by VS directly)

    Also, you can use the following command: 

    dotnet publish -f net8.0-ios -c Release -p:ArchiveOnBuild=true -p:RuntimeIdentifier=ios-arm64 -p:CodesignKey="XXX" -p:CodesignProvision="XXX"

    Best Regards,

    Wenyan Zhang
