I have already tried:

xcode-select --install 

and

xcode-select --reset 

Has anyone else run into this issue? How to fix it?

Answer 1

First, try updating Xcode through the app store

As a last resort, you can change your MacOS Date to

1st October 2019 

I set my system time to 1st October 2019, the date when the certificate was still valid. Then, I opened Xcode and followed the component install. This went well, and now Xcode works again.

Edit and set the date of your Mac as 1st October 2019.

Answer 2

What worked for me was updating Xcode in the App Store. After that I was able to install the additional components successfully.
