Release 2.0.0 has SPM support, but the above issue occurs due to Bolts being "unstable".

Failed to resolve dependencies Dependencies could not be resolved because package 'parse-sdk-ios-osx' is required using a stable-version but 'parse-sdk-ios-osx' depends on an unstable-version package 'bolts-objc' and root depends on 'parse-sdk-ios-osx' 2.0.0.

We would need to make a Bolts release with the changes in https://github.com/vazarkevych/Bolts-ObjC/tree/spm, but this branch is based on the original Bolts and our forked Bolts is out of sync with the original Bolts repo.
