Description
Message((__objc_no) is true) failed is shown in Xcode. This just refers to the assert itself, which is on boolean NO.
My branch which will repro this issue:
https://github.com/axi0mX/EarlGrey/tree/crash
Tested on Xcode 8, iOS 10 simulator (iPhone SE).
Contributor guide
Research direction
Start with the linked crash branch and reproduce the failure using the reported Xcode 8 and iOS 10 simulator setup. Trace the GREYAssert call inside the dispatch_sync block and compare its behavior with the reported assertion message. Done means the reproduction no longer crashes while the assertion still reports failures correctly.
