在 Swift 任何 iOS 设备的包构建中：在范围内找不到类型 'EdgeInsets'

Question

当我构建这个非常简单的 Swift 包时，我得到了这个编译器错误：

/Users/benleggiero/Desktop/Test/Sources/Test/Test.swift:4:11: error: cannot find type 'EdgeInsets' in scope
extension EdgeInsets: P {}
          ^~~~~~~~~~

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: "Test",
    products: [
        // Products define the executables and libraries a package produces, and make them visible to other packages.
        .library(
            name: "Test",
            targets: ["Test"]),
    ],
    dependencies: [
        // Dependencies declare other packages that this package depends on.
        // .package(url: /* package url */, from: "1.0.0"),
    ],
    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: "Test",
            dependencies: []),
        .testTarget(
            name: "TestTests",
            dependencies: ["Test"]),
    ]
)

Sources/Test/Test.swift

import SwiftUI

@available(iOS 13.0, *)
extension EdgeInsets {}

尽管您正在为 iOS 设备构建，但您似乎还必须在 Package.swift 文件中明确定义您的平台，以使其不给出这个错误：

let package = Package(
    name: "WhosebugLibrary",
    platforms: [
        .iOS(.v13),
        .macOS(.v10_15)
        ],
    //etc.

请注意，在我还执行“清理构建文件夹”之前，仅此一项对我仍然不起作用，此时它已正确编译。
