Also, very strangely, I left a comment in `PipelinesTests.swift:28` where you can replace one line of code with an equivalent line to remove the error.

We've started seeing an increase in crash reports to Alamofire for crashes in swift_checkMetadataState, as well as client projects (which shows an issue through tuple metadata). Some are from Xcode 11.3, most from Xcode 11.4 (Swift 5.2 compiler).
