ios - Swift 包 : Dependent Package can't be found. 补救措施？

Question

背景:我做了一个 successful package <--- dependency今天早些时候使用不同的依赖项作为“概念证明”。然而 Facebook SDK 包 无法识别依赖项:

这是 package.swift :

// swift-tools-version:5.3
// The swift-tools-version declares the minimum version of Swift required to build this package.

import PackageDescription

let package = Package(
    name: "CVSFacebookAccess",
    platforms: [
           .iOS(.v13)
       ],
    products: [
        // Products define the executables and libraries a package produces, and make them visible to other packages.
        .library(
            name: "CVSFacebookAccess",
            targets: ["CVSFacebookAccess"]),
    ],
    dependencies: [
        .package(name: "Facebook", url: "https://github.com/facebook/facebook-ios-sdk.git", from: "11.0.1")
    ],
    targets: [
        // Targets are the basic building blocks of a package. A target can define a module or a test suite.
        // Targets can depend on other targets in this package, and on products in packages this package depends on.
        .target(
            name: "CVSFacebookAccess",
            dependencies: ["Facebook"]),
        .testTarget(
            name: "CVSFacebookAccessTests",
            dependencies: ["CVSFacebookAccess"])
    ]
)

这是 Facebook 软件包:

问题:
为什么无法识别 Facebook SDK？
我正在关注相同的 Swift PM syntax as before .

Answer 1

Facebook SDK for iOS 包包括几个库，例如:FacebookCore , FacebookLogin , FacebookShare , FacebookGamingServices你应该依赖一个需要的人，例如:

...
.target(
    name: "YourPackage",
    dependencies: [.product(name: "FacebookLogin", package: "Facebook")]),
...

然后你可以在你的代码中使用这个库:

import FBSDKLoginKit

func createLoginButton() -> FBLoginButton {
    return FBLoginButton()
}
