## NSMutableDictionaryが必要な理由 swiftのDictionaryはクラスじゃないから。 https://developer.apple.com/documentation/swift/dictionary Unmanaged.passRetainの引数にするためにはクラスである必要がある。 ## NSMutableDictionaryからswift Dictionaryへの変換 基本的には as でできる。 ただしbool値に関してはNSNumberのため変換後に入るのが数値。 0,1 ではなく false, trueの値が必要な場合には変換用の関数を自前で作る必要がある。 今回はなかった。
