Good catch on pointing this out. Good thing Bitrise was able to show the error. Since Xcode 13 is near, this will be needed.

Edit: and our pipeline is using whatever is latest each pipeline run. So looking forward for the fix to be applied:

@bboyle18 Thanks for pointing this out; we haven't switched to an iOS 15 workflow yet and so hadn't gotten to this.

@rsukumar-cpi I'm going to take a look but if it's more involved, may end up assigning to you now that you're full-time.

EDIT: Notes for Rishab & myself - seems like it's due to the introduction of async/await in Swift 5.5 and an unfortunately named method in the version of Swift Package Manager that we're using based off of this commit in the package manager. Off the top of my head, that sounds like we'll need to either try to peg compilation to happen with Swift 5.4 or below OR see if we can update to a version of SPM that has that commit in it.

This will be addressed by #63. Will release that in the next day or so. For those interested in how this was resolved, see the PR comments.

This is resolved in v2.2.1.
