[Solved] Xcode must be fully installed before you can continue

This often happens when you're working on either in bare React native or Expo based iOS app. This can be easily solved using a simple command.

Open your terminal and run the command below

sudo xcode-select -s /Applications/Xcode.app

This error happens when the path of Xcode command line tools is not set. But, by running this command we are setting the correct Xcode path to the Xcode command line tools.

So, it'll be resolved automatically.
