Hi @apranesh,
I got your problem. This issue is often due to misconfiguration. So, you could try to uninstall all iOS dependencies and reinstall again.
To uninstall all iOS dependencies you could run the following command (Which will uninstall libimobiledevice, ios-webkit-debug-proxy, usbmuxd, ios-deploy and carthage)**:
$ brew uninstall --ignore-dependencies --force libimobiledevice && brew uninstall --ignore-dependencies --force ios-webkit-debug-proxy && brew uninstall --ignore-dependencies --force usbmuxd && brew uninstall --ignore-dependencies --force ios-deploy && rm -rf /usr/local/bin/ios-deploy && brew uninstall --ignore-dependencies --force carthage
And then, reinstall all of them in this right order:
$ brew install carthage
$ brew install ios-deploy && brew unlink ios-deploy && brew link --overwrite ios-deploy
$ brew install --HEAD usbmuxd && brew unlink usbmuxd && brew link usbmuxd
$ brew install --HEAD libimobiledevice && brew unlink libimobiledevice && brew link libimobiledevice
$ brew install ios-webkit-debug-proxy
After the reinstallation, you could back to Katalon and check if it could detect your real iOS device now.
