https://www.dropbox.com/s/ipgedtenxjzsm7q/Captura%20de%20pantalla%202016-04-26%2020.07.52.png?dl=0
Use of unresolved identifier 'CameraViewController'

答
有可能是一些导致此问题的问题。
您没有在您调用ALCameraViewController对象的文件顶部导入ALCameraViewController。 README.md不会告诉你这样做，但为了让你的项目能够识别它，这是必要的。
您没有Xcode 7.3和Swift 2.2。一些语法与Swift 2.1到2.2不同。所以确保你有你的操作系统，Xcode程序和Swift语言更新。
你可以直接在问题中发布你的代码和错误消息，而不是提供一个截图的链接？ – NobodyNada
是的，它已经准备好 –
现在，我得到的错误： pantalla6.swift：10：8：没有这样的模块'ALCameraViewController' –
