Xcode 9.3.1 components list empty, can't download iOS 10 simulators

Question

I am running Xcode 9.3.1 (9E501) and my Components list is empty, preventing me from downloading iOS 10 simulators.

I have tried:

• Deleting the following locations and re-installing Xcode:

/Applications/Xcode.app

/Library/Preferences/com.apple.dt.Xcode.plist

~/Library/Preferences/com.apple.dt.Xcode.plist

~/Library/Caches/com.apple.dt.Xcode

~/Library/Application\ Support/Xcode

~/Library/Developer/

• Manually deleting all my iOS simulators

• Nothing I tried seems to work. I am running a non-admin user and installed Xcode using the admin user, if that makes any difference. Project is universal, deployment target is 10.3 (don't think that should matter).

Answer 1

I was able to install iOS 10.3.1 manually via command line. Still not able to get Components to show anything.

# Install xcode-install command line tools
gem install xcode-install

# Use xcversion to install additional iOS versions
xcversion simulators --install='iOS 10.3.1'
