Swift Package Manager

Hello all.

A port I maintain, Sequel-Ace, has recently switched from including a dependency with CocoaPods (which vendors all dependency code alongside the main project in the same repo) to Swift Package Manager (which fetches at build time):

This is potentially yet another source of fetch-at-build problems that we’ve been seeing with other package managing ecosystems (Go, Haskell, etc.). But interestingly I can’t even get to that point: it seems packages can’t be fetched due to sandboxing issues.

Does anyone know how we might go about accommodating projects using SPM?
