AWS Device Farm fails to run tests built with Xcode 9

[codyd51]

AWS Device Farm fails to run any XCUITests built with Xcode 9, including this sample app.

The relevant automation output seems to be:

1515429974.454000	2721	20	Waiting for XCTest test bundle ready message
1515429974.844000	2721	10	WARNING: 01
1515429974.867000	2721	10	E/W result: 0

1515429975.173000	2721	40	Could not receive XCTest bundle ready message from testmanagerd, error code -7
1515429975.173000	2721	40	Failed to run execution mode 3

This issue has existed since, at least, October. See this forum post.

Is AWS Device Farm still being maintained for new iOS tooling? Is a fix for this in the works?

Thanks!
