Jenkins xcodebuild DVTAssertions: ASSERTION FAILURE DVTFrameworks-10179/DVTFoundation/Multicore/DVTFuture.mm:365

I faced DVTAssertions: ASSERTION FAILED problem today, when I try to build iOS swift project with Jenkins.

To solve problem, I just eject the connected iPhone from Mac's USB port. Still I don't know what is the reason. Problem occured only on Jenkins, not XCode.

Full build log:
