Unable to run XCTests on iOS device

I've recently noticed that I can't run tests on my iOS devices. I've tried on both an iPhone 5 and an iPhone 6. Both fail with an error like this:

2015-07-13 12:32:26.930 MyApp[1316:735999] Error loading /private/var/mobile/Containers/Data/Application/B23BED3F-5D59-4727-9AAB-1155A3F3A8F2/tmp/MyApp Tests.xctest/MyApp Tests:  dlopen(/private/var/mobile/Containers/Data/Application/B23BED3F-5D59-4727-9AAB-1155A3F3A8F2/tmp/MyApp Tests.xctest/MyApp Tests, 262): no suitable image found.  Did find:
    /private/var/mobile/Containers/Data/Application/B23BED3F-5D59-4727-9AAB-1155A3F3A8F2/tmp/MyApp Tests.xctest/MyApp Tests: mmap() error 1 at address=0x0042C000, size=0x00099000 segment=__TEXT in Segment::map() mapping /private/var/mobile/Containers/Data/Application/B23BED3F-5D59-4727-9AAB-1155A3F3A8F2/tmp/MyApp Tests.xctest/MyApp Tests
DevToolsBundleInjection: Error loading bundle '/private/var/mobile/Containers/Data/Application/B23BED3F-5D59-4727-9AAB-1155A3F3A8F2/tmp/MyApp Tests.xctest'

All the other test errors I've found on the net with this format are code signing errors. This doesn't appear to be the case here...

As with the other errors like this, the test waits for a minute or two, and then fails with a dump like this:

* thread #1: tid = 0xb3aff, 0x33d0e474 libsystem_kernel.dylib`mach_msg_trap + 20, queue = 'com.apple.main-thread', stop reason = signal SIGSTOP

    frame #2: 0x33c37d3a libdispatch.dylib`_dispatch_mgr_thread + 38


*** Canceling tests due to timeout in Waiting for test process to check in... If you believe this error represents a bug, please attach the log file at /var/folders/yz/xbdghvnj1_7fhsrwl5v232b40000gn/T/com.apple.dt.XCTest-status/Session-2015-07-13_12:31:55-JkrDBi.log

Any ideas why this might be happening?

So... despite my belief to the contrary, this is a code-signing issue. Manually setting the provisioning profile on the test target (not the product target) in Xcode got my test up and running through the device.

The test fails in a new and unexpected (something semaphore-related) way compared to the iOS Simulator, but that's a whole different discussion.

Hope this helps somebody.
