Xcode6.3、Swift1.2での変更点

More than 5 years have passed since last update.

swiftの勉強にネットにアップされているサンプルコードを写経してる時にエラーになる。
調べてみたら変更点があった。
自分用にまとめる
myDevice = device as! AVCaptureDevice
「as」→「as!」
びっくりマークが必要になりました。

override func touchesMoved(touches: Set<NSObject>, withEvent event: UIEvent) {

        // タッチイベントを取得.
        let aTouch = touches.first as! UITouch
}

「touches.object」→「touches.first」に変更

そのほかにもありますが引数が違うとエラーを吐かれた場合は一度Xcodeで入力補助を使いながら確認した方がいいみたい。
