WebDriverAgent function getPageSource hangs for over a minute

[donioe]

The problem

WebDriverAgent function getPageSource hangs for 65 seconds at a time due to an error in XCElementSnapshot.hitTest. This prevents using the WDA method "/source".

Environment

• Appium version (or git revision) that exhibits the issue: 1.8.2-beta
• Last Appium version that did not exhibit the issue (if applicable):
• Desktop OS/version used to run Appium: Mac OSX High Sierra
• Mobile platform/version under test: iOS 12 beta-10 with Xcode 10 beta-6 (problems exists since beta-4)
• Real device or emulator/simulator: Real device

Details

The current implementation of WebDriverAgent method XCUIElement+FBIsVisible.fb_isVisible uses the XCTest method XCElementSnapshot.hitTest which sometimes hangs for over a minute. Commenting out the line which uses this method solves the problem.

Code To Reproduce Issue [ Good To Have ]

Reproduces immediately with almost any app (even iOS SpringBoard):

1. Run WebDriverAgent when device is connected.
2. Open http://serverurl:8100/source
3. Wait until the response arrives.

This is known to be slow, unfortunately there is no workaround yet.
