Appium 1.6.3 - Test hungs - Wait Polling not working

The problem

I type a word in a search. This made a loader to appear. In my next step I am trying to tap a second a element. This leads Appium to make a POST. There I have expected conditions that keeps polling. While in prior versions my expected conditions worked just fine and polling was working in Appium 1.6.3 it hungs and the whole test stops at the point of the first POST request. If I put a static sleep that warranties loader has finished then test continues fine.

Environment

• Appium version (or git revision) that exhibits the issue: Appium 1.6.3
• Last Appium version that did not exhibit the issue (if applicable): 1.6.0
• Desktop OS/version used to run Appium: MacOS
• Mobile platform/version under test: iOS 10.2 (XCUITest)
• Real device or emulator/simulator: Real and Emulator

It must be this WDA issue: https://github.com/facebook/WebDriverAgent/issues/372

Try to use non-xpath locator as a workaround or apply visibility patch I mentioned in that WDA issue to your local WDA source

For the benefit of Googlers who get here (as I did), I’ll sum up mykola-mokhnach’s workaround from the other issue:

1. Assuming you installed appium globally (npm install appium -g), open /usr/local/lib/node_modules/appium/node_modules/appium-xcuitest-driver/WebDriverAgent/WebDriverAgentLib/Categories/XCUIElement+FBIsVisible.m with your favorite text editor.
2. Replace the content of XCElementSnapshot’s (BOOL)fb_isVisible method with the following: return !CGRectIsEmpty(self.frame) && !CGRectIsEmpty(self.visibleFrame) && (CGRectIntersectsRect(self.visibleFrame, self.application.frame) || ((self.application.interfaceOrientation == UIInterfaceOrientationLandscapeLeft || self.application.interfaceOrientation == UIInterfaceOrientationLandscapeRight) && self.application.frame.size.height > self.application.frame.size.width && CGRectIntersectsRect(self.visibleFrame, CGRectMake(0, 0, self.application.frame.size.height, self.application.frame.size.width))));
