Hands-On Design Patterns with Swift

Adding more targets

To add an executable target to our package, we will edit the Package.swift file to add a new short section under targets (the new target definition in bold):

        .target(            name: "swURL",            dependencies: []),        .target(            name: "swURLCli",            dependencies: ["swURL"]),        .testTarget(            name: "swURLTests",            dependencies: ["swURL"]),

Then, we create a new swURLCli directory under the Sources directory to contain the new swURLCli executable source files. Finally, add a main.swift file in swURLCli with the following content:

import Foundationimport swURLstruct Todo: Decodable {    let userId: Int    let id: Int    let title: String    let completed: Bool}func doTask(completion: @escaping (_ data: Todo?, _ error: Error?) -> Void) { let group = DispatchGroup() ...
