Appium Support for xcode 8 and MAC 10+

How to support xcode 8 and MAC 10+, I have installed Appium 1.5.x, and I am not able to Pre-Launch app on ios.

you need to use 1.6.X for any xCode 8+

Is there any graphic UI for Appium 1.6.x

no. i use ‘driver.getPageSource()’

When I tried to use ‘driver.getPageSource()’, I get InvocationTargetException. Due to this I am not able to check the view hierarchy.

The reported issue was fixed. I went through this discussion
