Xamarin iOS code signing key not found in keychain-CodePudding

I'm trying to debug my Xamarin.Forms application on a physical iPhone, from my windows machine.

I have a Mac connected, and an iPhone connected to that Mac
I have an Apple developer certificate
I set up automatic provisioning using Visual Studio
I downloaded the generated certificate, and installed it:
- On the Mac in the System keychain and Login keychain
- On my windows machine running Visual Studio

When I try to deploy my application in Debug|iPhone, I get the following error:

iOS code signing key 'Apple Development: John Doe (5L4565FZ2L)' not found in keychain.

More details from the build output in Visual Studio:

I'm not sure which device is missing the signing key, but I assume it is the iPhone, since I installed the certificate on the Mac.

If this is the issue, how can I transfer the certificate to the iPhone? I already tried by deploying an empty app from Xcode on the Mac to the iPhone, but that didn't work.

You can workaround the issue by removing the flag from the debug builds in the .csproj file. Try to follow this link : Check
