1.  While type-checking getter for frame at <invalid loc>

很困惑这里的问题是什么。我已将 AnnotatePhotosVC.swift 的内容复制到一个单独的项目中以检查是否有错误，但没有任何错误。但似乎 Firebase 可能存在问题，但我的类 AnnotatePhotosVC 不使用 Firebase 或引用它。这个错误打印是什么意思？我应该寻找什么？任何指点将不胜感激!

这可能是一个太晚的答案，但问题是 xcode 编译器正在崩溃。这应该“永远不会发生” =)，但是最近版本的 xcode 和 swift3 一直有 bug 且脆弱(xcode 8.x)...当我将旧的 firebase 项目移至swift 3 和最新的 firebase cocoapods(即 3.7.1+)。我希望我能告诉你哪些组件​​导致了这个问题，但这很大程度上取决于你的 xcode 版本。我建议您迁移到 xcode 8.1 的 GA 版本，并将您的环境设置为纯 Swift 3，无需遗留 swift 编译，然后安装 Firebase 的最新 pod，您应该没问题! (这对我有用)。
