Description
Xcode 9 betas (at least 2 through 5) often stop with this error when working on ARKit projects when trying to install and debug on the device:

Opening this for tracking but does not seem to be specific to anything about `mapbox-arkit-ios`. Once it happens, it often happens for every other install/run attempt so usually simply trying again works. Often a full restart of Xcode avoids the issue for a bit but it'll inevitably come back.

Research direction
No repository file, test, or entry point is named.
