The joy of C++ interoperability with Swift.
You're looking at ~20 consecutive attempts to archive a new version of Preflight. Each one took approximately 20 minutes. That was my entire day.
Why put up with it? Because what's inside is worthwhile. Preflight wraps seriously powerful USD tooling via Swift-Cxx interoperability; the app's hidden complexity is part of what makes it valuable in the first place.

This time was especially difficult because we upgraded to SwiftUsd 6, which contains a new version of OpenUSD. But now, finito. The new version is being reviewed.
And just the fact that we can ship a native Swift app with this level of USD tooling is motivating...
