[nitpick] can we use SystemTime instead?

The cargo make thing works great for me!

I'd also commit (local) Package.swift to packages/swift if you don't mind - does not pollute the others.

I'll try to complete the Swift distribution path in the meantime.

[pblazej]

Here's more or less everything we need for local distribution, the tricky part is:

[tasks.swift-generate-manifest.env]
SPM_URL = { value = "https://dummy.com" }
SPM_CHECKSUM = { value = "1234" }

Let's assume the following workflow:

• create tag rust-sdks/livekit-uniffi@*
• create a release here with the artifacts

optionally:

• create a corresponding release for https://github.com/livekit/livekit-uniffi-xcframework
  • if the versioning is separate, we cannot predict the URL
  • checksum may be unstable as gh zips everything by default, the same problem occurs for webrtc

Alternatively, we can skip Package.swift generation for release whatsoever and just track it in the above repo (it won't change that often). It will also bypass the cocoapods legacy problem here.

I made a manual pre-release here: https://github.com/livekit/livekit-uniffi-xcframework
Swift SDK support: livekit/client-sdk-swift#822

@ladvoc if you're able to finish the release pipeline here, that would be cool (artifact is OK as mentioned above).

And one more thing @ladvoc static release is still ~40MB whereas dylib ~1.8MB.

Dynamic one won't pass AppStore validation (we'd need to wrap it in a Framework).

90426: Invalid Swift Support. The SwiftSupport folder is missing. Rebuild your app using the current public (GM) version of Xcode and resubmit it.

I'd rather go for stripping the static one further, any ideas?

iOS in --release profile:

Ar Archive - 47 MB

Okay, looks like DEAD_CODE_STRIPPING does the job and the bundle size increase is negligible (0.1 MB), moved back to static 729bc10

It also passes 🍏 validation 👍

I'm still open to optimization ideas 😄
