I have updated macOS to version 13.5.1, Visual Studio to version 17.6.3, and Xcode to version 14.3.1. I have an older Xamarin.iOS project that was created in 2016. While the project can build, and I can use it on the simulator, I am encountering an issue where the storyboard does not open. I receive the following error message: "Error updating Objective-C type information."
Is there anyone who has experience dealing with this issue? Alternatively, is there a way for me to access more detailed error information?
The solution is to migrate your old Xamarin.iOS project to .NET iOS. During the migration, if you have numerous dependencies such as NuGet packages, you must handle all of them. Additionally, remember that many of the packages have been deprecated and has no support. You should obtain the source code, build them with your .NET iOS project's .NET version, and use the NuGet packages as DLLs.
