Updated for swift :

below solution works for me:

    let mVal = 26513 // hex value of mVal = 0x6791 (UInt16)
    let highByte = (mVal >> 8) & 0xff  // hex value of highByte = 0x0067 (UInt8)
    let lowByte = mVal & 0xff // hex value of lowByte = 0x0091 (UInt8)

    print("highByte: \(highByte)\nLowByte: \(lowByte)")
