Working on Zoul's answer from above link. part 1) Wire the writer

到目前为止我有：

let paths = NSFileManager.defaultManager().URLsForDirectory(.DocumentDirectory, inDomains: .UserDomainMask)
    let documentsURL = paths[0] as! NSURL
    let videoWriter:AVAssetWriter = AVAssetWriter(URL: documentsURL, fileType: AVFileTypeQuickTimeMovie, error: nil)

    var videoSettings: NSDictionary = NSDictionary(

我无法弄清楚他的正确Swift版本

I can't figure out the correct Swift version of his

NSDictionary *videoSettings = [NSDictionary dictionaryWithObjectsAndKeys:
AVVideoCodecH264, AVVideoCodecKey,
[NSNumber numberWithInt:640], AVVideoWidthKey,
[NSNumber numberWithInt:480], AVVideoHeightKey,
nil];

推荐答案

构建字典字面很简单：

import AVFoundation

let videoSettings = [
    AVVideoCodecKey: AVVideoCodecH264,
    AVVideoWidthKey: 640,
    AVVideoHeightKey: 480
]

至于其他一切，我建议你阅读Apple的 Swift编程语言首先建立基础，而不是依赖于SO或教程恰巧涵盖了你想做的事情。正如他们所说，教一个人钓鱼。

As for everything else, I would encourage you to read through Apple's The Swift Programming Language to establish fundamentals first, rather than relying on SO or tutorials that happen to cover what you want to do. "Teach a man to fish", as they say.
