How to update Xcode from 7.2.1 to 7.3.1 using terminal (commandline tools) I just need to know if there's a way to update Xcode from 7.2.1 to 7.3.1 using terminal (command line interface)?

The reason is I updated the Xcode via Mac App Store and once it was installed, the Xcode is still showing the version as Xcode 7.2.1.

I've been searching here as well as over Google and I couldn't find any info regarding this.
Depending upon the version of macOS/OS X that you have installed as well as your boot volume's storage, you might not see the version of Xcode.app in your /Applications folder update immediately after updating from the App Store app.
