iOS 应用程序在转换为 Swift 3 后未启动

Question

我已将现有应用程序转换为 Swift 3，但是当我尝试从 Xcode 启动它时，没有任何反应。

确切地说，应用程序已成功安装、打开，但仅显示白屏。没有构建时或运行时错误。

我在 private func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool 中放置了断点，但它没有到达那里。

在模拟器中启动会在控制台中打印以下内容：

帮忙？任何人？请。

Answer 1

产品 -> 方案 -> 编辑方案然后在左侧的运行部分，select 参数选项卡 -> 环境变量：

OS_ACTIVITY_MODE 值：禁用。

从Cocoapods中移除框架，通过复制项目中的SDK手动安装。

Answer 2

尝试替换

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {

对此：

func applicationDidFinishLaunching(_ application: UIApplication) {
