iOS App build is .ipa (it's not .dmg file which happens for Android App build). I will archive xamarin forms app in VS to create the .ipa file for iOS. Do you have latest Xcode installed and paid Apple developers account to create certificate and provisioning profile?
Hello dear. I hope you are doing well.
I'm Ali, a software engineer and IOS developer.
I have Xcode 13 on my mac, and i can archive your code immediately.
Just send me your code and your developer credentials.
Thanks for yours time.
