Note:

  1. The Same setup is working with Selenium-Java(2.53.1) and Java-Client(4.1.2)
  2. I have tried different combinations with selenium and java client after browsing through the same issue posted by others but no luck

Please help me with this and let me know there is something i am missing out.

Hi Frnds,

I found the solution, but cant explain how it works. But it works for me as a miracle.

Just add the below line, and magic happens. I dont have any idea how that makes it work…HAHAHA…

capability.setCapability(MobileCapabilityType.NEW_COMMAND_TIMEOUT, “60”);

Thanks for taking time to help but this is not working.
I could not figure out which version of selenium and java-client to be used with appium 1.9.1 server to work on ios12(Using Xcode 10.0)

It’s a Compatibility issue. Upgrade the Appium Version
