swift ,バイナリファイルを読み込み,Data型を[UInt8]や[Int16]に変換

Data型->[UInt8]

    func ReadBinaryFile_Int8(path : String) -> [UInt8]{
        let dataURL = URL(fileURLWithPath: path)
        var binaryData = Data();
        do {
            // ファイル読み込み
            binaryData = try Data(contentsOf: dataURL, options: [])

        } catch {
            print("Failed to read the file.")
        }
        //return binaryData.encodedHexadecimals!;
        return [UInt8](binaryData)
    }

Data型->[Int16]

    func ReadBinaryFile_Int16(path : String) -> [Int16]{
        let dataURL = URL(fileURLWithPath: path)
        var binaryData = Data();
        do {
            binaryData = try Data(contentsOf: dataURL, options: [])
           
        } catch {
            print("Failed to read the file.")
        }
        
        let i16array = binaryData.withUnsafeBytes{UnsafeBufferPointer<Int16>(start: $0, count: binaryData.count/2).map(Int16.init(bigEndian:))}
        
        return i16array;
    }
