上一篇埋個伏筆，今天我們來玩 Swift package 吧。

今天介紹用FLEX加入到 Swift package。
Copy HTTPS 的 URL, 評估一下選多少 Releases version

Xcode 導覽頁 -> File -> Add Packages

設定一下 Up to Next Major Version

Add Packages 後

FLEX 進入專案囉～

Add new Group, 做好專案資料整理。
建個 Managers 資料夾

command + N , create a new Swift File

import SwiftUI
#if DEBUG
import FLEX
#endif

class LibsManager {
    static let shared = LibsManager()

    func setupLibs() {
        // No need for UIWindow in SwiftUI
        let libsManager = LibsManager.shared
        libsManager.setupFLEX()
    }
    
    func setupFLEX() {
        #if DEBUG
        FLEXManager.shared.isNetworkDebuggingEnabled = true
        #endif
    }
}

extension LibsManager {
    func showFlex() {
        #if DEBUG
        FLEXManager.shared.showExplorer()
        #endif
    }
}

我們用Singleton pattern 來管理套件。

初始化 LibsManager.shared.setupLibs()

init() {
        LibsManager.shared.setupLibs()
    }

放這裡

@main
struct SwimmingStrokesApp: App {
    init() {
        LibsManager.shared.setupLibs()
    }

    var body: some Scene {
        WindowGroup {
            ContentView()
        }
    }
}

加個神奇的按鈕
加個神奇的按鈕

import SwiftUI

struct FlexButton: View {
    #if DEBUG
    let screenSize = UIScreen.main.bounds.size

    var body: some View {
        Button(action: {
            LibsManager.shared.showFlex()
        }) {
            Text("F")
                .frame(width: 50, height: 50)
                .background(Color.orange)
                .foregroundColor(.white)
                .clipShape(Circle())
                .padding(.all, 10)
        }
        // TODO: 先不要
//        .position(x: screenSize.width - 35, y: screenSize.height - 75)
    }
    #else
    var body: some View {
        EmptyView()
    }
    #endif
}

struct FlexButton_Previews: PreviewProvider {
    static var previews: some View {
        FlexButton()
    }
}

加這段 code

#if DEBUG
FlexButton()
#endif

FLEX 很多功能，可以去玩玩看，
我要放連假囉，下集待續
