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: // 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.

My Catalyst-capable apps stopped building with the newly released Xcode 12. I tested it out also on a brand new SwiftUI project with the same result. I have my App structure looking like the fragment below. This is the code that was generated by Xcode; no modifications. import SwiftUI @main struct TestApp: App {     var body: some Scene {         WindowGroup {             ContentView()         }     } } I get the following compiler errors: 'TestApp' is annotated with @main and must provide a main static function of type () -> Void or () throws -> Void Cannot find type 'App' in scope Cannot find type 'Scene' in scope This code compiles fine when I build for an iPhone or iPad device. Is anyone else seeing this? Any ideas on how to fix it?
