Superscript (iOS)

A Common Expression Language (CEL) evaluator used by SuperwallKit, built in Rust and shipped as a binary XCFramework.

This is the slim successor to superscript-ios. Unlike the original repo — which committed the ~250 MB libcel.xcframework into git on every release and grew to ~1.2 GB of history — this repo keeps the git tree tiny and distributes the framework as a GitHub Release asset. SPM's binaryTarget(url:checksum:) downloads it on demand.

Swift Package Manager

.package(url: "https://github.com/superwall/superscript-ios-next.git", from: "1.0.0")

Then add Superscript as a target dependency.

CocoaPods

pod 'Superscript', '~> 1.0'

The pod's prepare_command downloads the xcframework from the matching GitHub Release at install time.

How releases work

Releases are produced by .github/workflows/release.yml in response to a repository_dispatch event triggered by the upstream Rust repo, superwall/superscript. On each release the workflow:

1. Builds libcel.xcframework from the Rust source.
2. Zips the framework and uploads it as a release asset on a new tag.
3. Computes the Swift Package Manager checksum and rewrites Package.swift and Superscript.podspec to reference the new release.
4. Commits the (small) text changes and pushes the tag.

No binaries ever land in git.
