Use of unresolved identifier 'CameraViewController'

我正在使用https://cocoapods.org/pods/ALCameraViewController

Answer 1

可能有许多问题导致此问题。

1. 您没有在调用 ALCameraViewController 对象的文件顶部导入 ALCameraViewController。 README.md并没有告诉您这样做，但为了让您的项目识别它，这是必要的。

2. 您没有 Xcode 7.3 和 Swift 2.2。某些语法与 Swift 2.1 到 2.2 不同。因此，请确保您的操作系统、Xcode 程序和 Swift 语言已更新。
