I am trying to debug my MAUI app on a real iOS device for push notifications. I have a remote mac connection to my mac book[Sonoma 14.5], Visual Studio 2022 [Version 17.9.7], Xcode [15.2] iOS Device[17.5] and no matter what I do I get this error : code object is not signed at all
- Tried removing every sub directory in resource folder
- Tried using both Auto. and Manual Provisioning. Even logged in via API instead of email and pass to apple developer and still no luck.
- Removed everything related to push notifications to simplify the certificate and provisioning profiles
here is the build log I get every time no matter what changes I make.

2024-05-30T21:22:10.05+00:00 unfortunately no. I have tried to downgrade iOS but it seems that 17.2 is not signed anymore so I'm stuck with version 17.5. I have to find a way to downgrade my phone since no other device without update is around.

Bruce (SqlWork.com) 66,061 Reputation points2024-05-30T23:20:36.9933333+00:00 Xcode 15.2 only supports up to 17.2. There are reports that installing above 17.2 can break Xcode 15.2. The easiest fix is to upgrade to Xcode 15.3.
thread on getting 15.3 working:

2024-06-03T11:32:46.4966667+00:00 @Bruce (SqlWork.com) Thanks for your guide. but it is the same situation. upgraded everything to latest version (vs preview on windows, .net 8.0.301 on both mac and windows, switched to dev kit pre-release on vscode ...) but still I cannot bundle sign the app using vscode or visual studio remote or local vs for mac.

- Have you configured APNS provisioning profile on Apple Developer connect portal? Did you add the
aps-environmentkey in the entitlements file? See iOS entitlements - .NET MAUI | Microsoft Learn - How did you configure the notification provisioning profile? You can refer to the following doc and double-check if the provisioning profile is correct.
Push Notifications in iOS - Xamarin | Microsoft Learn (This doc is about Xamarin, it applies to MAUI)
- Could you debug an empty MAUI project on your physical device (without APNS)? If so, we can identity that the issue only occurs in your current project. (Tips: please select Automatic provisioning, and make sure you have the Wildcard App IDs and the matched provisioning profile. See Automatic provisioning for .NET MAUI iOS apps - .NET MAUI | Microsoft Learn If you have any concerns, please feel free to post in here)
- Do you have other devices? Does this issue occur on other iOS devices (lower than iOS17.5)?
