MobileDevice.pkg untrusted, cannot open Xcode after OS X update

Question

After an automatic update of macOS v10.15 (Catalina), I am unable to open Xcode. Xcode prompts me to install additional components but the installation fails because of Mobi

Answer 1

At macOS Catalina

cd /Applications/Xcode.app/Contents/Resources/Packages
sudo rm -rf MobileDevice.pkg
sudo rm -rf MobileDeviceDevelopment.pkg 

Try again. It means you entered on the Xcode downloaded packages and remove it. I really don't understand how Apple do but if you remove Xcode will download it again and revalidates.

Some remarks, I'm on XCODE Version 11.0 (11A420a) if you are not this is not guaranteed to work.
