Hi @marian_magdy,

It sounds like Xcode might not be installed correctly. Can you try installing either:

Xcode 9.4.1: [https://download.developer.apple.com/Developer\_Tools/Xcode\_9.4.1/Xcode\_9.4.1.xip](https://download.developer.apple.com/Developer_Tools/Xcode_9.4.1/Xcode_9.4.1.xip)

or

Xcode 10.1: [https://download.developer.apple.com/Developer\_Tools/Xcode\_10.1/Xcode\_10.1.xip](https://download.developer.apple.com/Developer_Tools/Xcode_10.1/Xcode_10.1.xip)

I would also recommend Katalon Studio version 5.10.1: [https://github.com/katalon-studio/katalon-studio/releases/tag/v5.10.1](https://github.com/katalon-studio/katalon-studio/releases/tag/v5.10.1)

Once those are installed, can you try to run from the Terminal:

`xcode-select -p`

You should see something like `/Applications/Xcode.app/Contents/Developer` assuming that you installed Xcode at `/Applications/Xcode.app`

Hope this helps,

Chris
