I'm writing a Xamarin app with Visual Studio 2019.
The app deploys fine on an Android and Android simulator.
The app also deploys fine on an iOS simulator.
But when I try to use the phone which is connected wirelessly to my MAC I receive error:
Failed to codesign 'bin/iPhone/Debug/MyFirstProject.iOS.app': Warning: unable to build chain to self-signed root for signer "Apple Development: xxxxxxxxx"
/Users/xxxxxxxx/Library/Caches/Xamarin/mtbs/builds/MyFirstProject.iOS/b3abbddebddecdd063975729ce3a99c630351cdb91eae3b0eaddcd0abeceb326/bin/iPhone/Debug/MyFirstProject.iOS.app: errSecInternalComponent MyFirstProject.iOS
Any idea how to resolve?

The key point is this sentence: unable to build chain to self-signed root for signer. You can check if your root CA from Key Chain Access is expired, I'm afraid you should generate a new certificate. For more information , you can refer to:

My certificate is brand new.
When I connect the iOS phone to my computer with a USB cable, right click on OS project and deploy, it works (found this solution researching).
However, when I try to run it wirelessly, I receive that error.
I try to deploy an app to my own device with WIFI, it works. If you could deploy app with USB rather than WIFI , maybe you can clean the build, check Apple Worldwide Developer Relations Certificate Authority and connect the device again. In addition, may I ask what your version of VS is ?
I am using a USB. Only way I can get it to deploy.
I'm so sorry it still doesn't work wirelessly. Fortunately, It can be deployed by usb.
Also, the certificate was created on my Mac Air device by VS 2019 after I set up automatic.
The certificate is new.
