question
ios swift
初回起動時にファイルをバンドルからコピーするメソッドがコンパイルエラー
Swift 2では`NSError`を使ったエラー処理は`do〜try〜catch`構文に変わっているので、旧来の書き方ではコンパイルエラーになります。

以前と同様の処理をするには、たとえば下記のように書きます。

```

    do {
        try fileMan.copyItemAtPath(source, toPath: dbPath)
    } catch let error as NSError {
        print("RealmDB - failed to copy writable version of DB!")
        print("Error - \(error.localizedDescription)")
    }
    
```
