ios - 转向 Swift 3.0，构建问题

Question

关于将 iOS 应用程序迁移到 Swift 3.0 的过程。我终于摆脱了(所有)语法错误。

不过，我似乎还有一个很大的问题。

以下是我在构建项目时在 Xcode 中得到的最终错误消息:

这里太长了，所以我决定在途中选择一些带有.....(点)的部分来缩短它。我希望这足以让您了解正在发生的事情。

我不希望在这里有明确的解决方案(认为它会很棒)。但是，如果有人可以指出我应该关注哪个方向来构建我的项目，那就太好了。感谢您提供任何相关提示。

Answer 1

一些语法在 swift 3 中发生了变化，例如:

func scrollViewDidEndDecelerating(scrollView: UIScrollView) {}

现在

func scrollViewDidEndDecelerating(_ scrollView: UIScrollView) {}
