macOS "Install additional required components" error every time I open Xcode 7.

[chrono1081]

Hi guys,

Every time I open up Xcode I get this error:

"Install additional required components? Xcode requires additional components to support running and debugging. Choose install to add required components."

I choose install each time but it keeps asking me every time I open Xcode.

I'm on Xcode 7.2.1 and on El Capitan. Every thread I see with others having this issue are on beta versions of Xcode, mine isn't a beta version. Anyone know how to fix this?

Two things come to mind:
1. Install components via the command line:

/Applications/Xcode.app/Contents/MacOS/Xcode -installComponents

It might require SUDO and an admin password.

2. Noticed one user reset his password by

entering recovery mode (CMD+R on startup), started Terminal.app and typed

resetpassword

and reset the root password. Not sure why this enables Xcode to work. YMMV and I don't trust this to solve the problem.
​

3. One sure way is to clean install OS X via recovery mode and then clean install Xcode( sorry, I know that can be painful )
