Adopts Swift 6 and its data race safety features. This should be a non-breaking change in terms of code (it didn't require changes to the sample app used to test the SDK), but does seem to require being on the latest XCode beta which could trigger some workflow breakage. I'm not sure the best way to handle that in terms of versioning, but in any case I'm temporarily blocked by the supported CI actions.
To make this work, the following changes were adopted:
@MainActoradded to the SDKSendableadded to a couple data structuresASPresentationAnchor.defaultextension reworked as a computed property instead of afileprivate letnonisolated(required for protocol compliance), and some of their internals are wrapped inTask { @MainActor in ... }to get back to the right actor.I tried a couple other approaches that felt like they'd be less likely to hog resources on the main thread (generally, trying to make
SnapAuthconform toSendableor turn into anActor) that clearly weren't going anywhere without pretty substantial refactoring. I won't pretend to be a Swift expert; if someone who is chimes in with a better way, this can be revisited.Posting as-is for review, but the CI tooling will need some updates before this will build and can be landed. I expect this will solidify closer to the fall OS releases.
Fixes #26
