Running any XCUI tests on device crashes. Steps to Reproduce: 1. Open Xcode 9.0 beta 3. 2. Create a new single-view iOS application project. Be sure to include UI tests. 3. Run the testExample UI test on a device. 4. Observe that the UI test runner crashes in -[XCTRunnerIDESession initWithTransport:] Expected Results: The UI tests should run successfully and exit cleanly on the device. Observed Results: The runner crashes reliably. Version: Xcode Version 9.0 beta 3 (9M174d) macOS 10.12.5 (16F73) Notes: This looks like a method call on an invalid pointer, because the crash isn't often the same between two separate runs. Sometimes it invokes unknown selectors, sometimes it calls random functions, etc. As requested, I attached the session crash log, but this should be easily repeatable. Configuration: I have seen this issue on an iPhone 6 running iOS 10.3.2 (14F89).
