OS: 12.14.5 Xcode: 10.2.1 Katalon: 6.2.0 Appium: 1.12.1 iOS Simulator: 12.2 Simulator device: iPhone XS Been trying to run my first test in Katalon, but I can’t get the application to open. Installed/reinstalled all of the required components a number of times, rolled Appium back to 1.8.2-beta, uninstalled io.uiautomator2.server and io.automator2.server.test, etc. etc.. I’m sure I’ve probably missed something simple, but for the life of me I can’t find what it is. Application path is accurate and I’ve built the app directly from XCode to the simulator successfully several times - it just won’t build in Katalon. I had a similar problem while trying to test this in Appium and found I needed to use `session-override` in the server configuration. Is there a way to include this in Katalon’s custom desired capabilities? If so, I’ve not found any documentation for it and would appreciate a pointer. Thanks in advance for assistance! ![11%20AM](https://europe1.discourse-cdn.com/katalon/original/2X/5/57b932350c26c53831ef4568878b13d54d602840.png) > e[35m[Appium]e[39m Welcome to Appium v1.12.1 >
