Creating Swift Wrapper over XCFramework in Swift Package

I'm trying to use libgit2 in an iOS application. I've packaged up libgit2, libssh2, libssl, and libcrypto in XCFrameworks. The XCFrameworks support iOS arm64, simulator, and Catalyst. I want to build a Swift wrapper over the frameworks and deploy them using a Swift Package.

When I link against the XCFrameworks directly in my application, I can consume libgit2 by creating a bridging header and #import <git2.h> from libgit2.xcframework. When I move the code into a Swift Package, it fails to build or find libgit2 even though it's part of the package. I can't find any indication of whether I need a bridging header or how to add the bridging header to my Swift package.

Here's my Package.swift file:

Code Block swift
// swift-tools-version:5.3
import PackageDescription
let package = Package(
  name: "Git",
  platforms: [.iOS(.v13)],
  products: [
    .library(
      name: "Git",
      targets: [
        "SwiftGit"
      ]
    ),
  ],
  targets: [
    .target(
      name: "SwiftGit",
      dependencies: [
        .target(name: "libcrypto"),
        .target(name: "libssl"),
        .target(name: "libssh2"),
        .target(name: "libgit2")
      ]
    ),
    .binaryTarget(
      name: "libcrypto",
      path: "lib/libcrypto.xcframework"
    ),
    .binaryTarget(
      name: "libssl",
      path: "lib/libssl.xcframework"
    ),
    .binaryTarget(
      name: "libssh2",
      path: "lib/libssh2.xcframework"
    ),
    .binaryTarget(
      name: "libgit2",
      path: "lib/libgit2.xcframework"
    )
  ]
)

The documentation seems to indicate that I can reference binaryTarget dependencies in a Swift target in order to create a wrapper library. Can anyone help me to understand what I am missing here? How do I create the equivalent of a bridging header so that I can access the native frameworks from my Swift code?

Thank you.
