// RTCAdapter — closed-source release manifest.
// Shipped alongside RTCAdapter-<VERSION>.zip to a standalone release repo.
//
// Consumer usage:
//   .package(url: "<release repo git URL>", from: "<VERSION>")
//   main app target:  .product(name: "RTCAdapter", package: "<repo name>")
//                     import RTCAdapter
//   extension target: .product(name: "RTCAdapterScreenShareExt", package: "<repo name>")
//                     import RTCAdapterScreenShareExt
//
// Publishing (scripts/release-adapter.sh automates the placeholder filling):
//   1. Fill in the placeholders below:
//      - <TODO_RTCADAPTER_URL>                  remote URL of the RTCAdapter zip
//      - <TODO_RTCADAPTER_CHECKSUM>             its checksum
//      - <TODO_RTCADAPTERSCREENSHAREEXT_URL>    remote URL of the RTCAdapterScreenShareExt zip
//      - <TODO_RTCADAPTERSCREENSHAREEXT_CHECKSUM>  its checksum
//   2. Push this Package.swift + Sources/RTCAdapterTRTCLink/ to the release repo.
//   3. git tag <VERSION>.
//
// This manifest is fully self-contained: AmazonIVSBroadcast and the TRTC
// frameworks are declared as binaryTargets, with no external SwiftPM package
// dependency. That is required — a package consumed by a version tag cannot
// depend on a revision/branch-pinned package, so we reference the vendor
// xcframework zips directly instead of the Professional_SwiftPM package.
