@cwisecarver, any chance of getting this PR looked at soon? Our team plans to integrate soon, and we'd love to have SPM support from the start.

@BetweenTwoBits @eddie-zhang Could you provide a brief description to the PR / comment of how we can verify this change works and doesn't cause regressions?

[eddie-zhang]

This PR only provides the package.swift file which is needed by SPM. The repo would need to have releases tagged with git tags in addition, in order to support SPM. I don't believe package.swift is used by anything other than SPM so I don't see it causing a regression.

Thanks @eddie-zhang! Could you point to a guide that outlines how to implement the below (and any other requirements needed to support SPM)?

Thanks @eddie-zhang. The release is here: https://github.com/Parsely/AnalyticsSDK-iOS/releases/tag/0.2.1. Let me know if that works for you!

@abelsonlive why close the PR rather than merge it? I think we'd all assume that you'd keep supporting people implementing via SPM

[abelsonlive]

@BetweenTwoBits I added support via: c1a3bd0. It was faster to make the commit myself than request changes.

Here's the release: https://github.com/Parsely/AnalyticsSDK-iOS/releases/tag/0.2.1

Hey @abelsonlive -- there's a fatal error in Xcode when integrating with SPM because of this missing line

[cwisecarver]

Sorry @eddie-zhang, we've got separate work on-going to add SPM support. I've reverted these commits for now. I'll @ you on the PR once we're ready to merge it.
