Anybody faced the error while calling Takescreenshot on iOS 11?

Try updating to 1.7.0 beta first, thats the version that has iOS11 support:

npm install [email protected]

You should update your selenium (3.5.3) and java-client (5.0.3) version also.

@Telmo_Cardoso Thanks for the details. I will update the Appium version to 1.7.0 and try from my end.

@sanoj27
Can you share the setup required for automating iOS11.
For iOS10 currently we are installing WDA through xcode 8.3.3… is there anything elese to do for iOS11 ?

@Kishore_v same setup is working with iOS 11

@Swapan_Chhabra
I tired with the same setup, upgraded the appium to 1.7.1 and Mac os to 10.12.6… webdriver agent got installed in the device.
But i am getting error while executing test scripts, “Failed to create WDA session”
In release notes its mentioned like “use xctestrun file to launch WDA”, u have any idea on this ?
