With the Catalina upgrade, my Xcode did not automatically update to 11.1. The App Store kept trying to update Xcode each night through automatic updates. On its own, it never succeeded. Once it reported it could not download Xcode: Unable to Download App. 'Xcode' could not be installed. Please try again later.

• So the solution is to compile Xdebug manually, manually specifying the actual location of the header files, which are still provided by Xcode, just at a different location. The first step is to get Xcode from the App Store. Once Xcode installed, we have to get the command line tools: xcode-select -install.
• If the answer is “yes”, then you will need to download and install Xcode from the Apple App Store. Xcode is a Mac application built by Apple, and it cannot be installed with Homebrew.

• Installing Xcode provides the C compiler that is used by Qt Creator. To choose the correct Xcode installation, you need to know your macOS version. Select menu - 'About This Mac' and read the macOS version number. If your macoS version is Catalina = 10.15, you can install the latest Xcode directly from the App Store by following these steps.
• Installing Homebrew. First, we need to install Homebrew. Homebrew allows us to install and compile software packages easily from source. Homebrew comes with a very simple install script. When it asks you to install XCode CommandLine Tools, say yes. Open Terminal and run the following command.

Xcode may be an 8GB download, but its installation requires double-digit final storage, plus any temporary storage that it takes during the installation process. I would not attempt it with less than 20 GB of available storage. Ideally more.

I just removed Xcode 11.3.1 from a Mojave 10.14.6 system and it freed up 27GB of storage after emptying the Trash.
