iOS12 Support

Hi, does anyone knows if Katalon will support iOS12 anytime soon?

Hi Ali,

I haven’t heard an ETA on Xcode10/iOS12 support yet. But, as far as I know, you can build an app in Xcode10 (and iOS 12) but you’ll still need to have Xcode9.4.x around for some of the command line tool that Katalon Studio uses behind the scenes.

You can do this by going to and downloading the older version of Xcode.

You’ll be asked to “Keep Both” when you install - do that. I named mine “”. Then you’ll have to set the default version to the older version:

sudo xcode-select -s /Applications/

Enter your login/system password when prompted.

Now you can use Xcode 10 to develop, but still run Katalon Studio.

Hope this helps,


You can use Appium 1.8.2-beta to work with Xcode10 and iOS12 devices:

npm install -g appium@1.8.2-beta.

Thanks to @Frank_Keefer!
