I am working on a project where I have to read data from device and then convert it in byte array and then read some bytes(4 byte) and convert them in float and use it. I have code that is working fine but in android but I am unable to convert the code correctly. Here is the android code

try {
          byte[] data = Arrays.copyOfRange(mScanRecord, 5, 9); //mScanRecord is byte array (byte[]) containing 11 byte
          searchModel.setData("" + ByteBuffer.wrap(data).getFloat());
    } catch (Exception e) {
          e.printStackTrace();
          searchModel.setData("" + 0);
And here is the code that I converted in swift 
typealias Byte = UInt8
func fromByteArray<T>(_ value: [UInt8], _: T.Type) -> T {
    return value.withUnsafeBytes {
        $0.baseAddress!.load(as: T.self)
func getUnitValue(byteArray:[UInt8]) -> Float {
    let value = fromByteArray([byteArray[7], byteArray[8], byteArray[9], byteArray[10]], Float.self)
    return value
..... In Some function I call .....
searchModel.setData(data: String(format: "%.10f", getUnitValue(byteArray: byteArray)))
It is giving me value but value is very different from android 
I am expecting value around 
2.0405695(like in android)

2.0405587
2.0526589
but I am getting 
547669365842.0000
-652321236542.0000
0.000000103
value changes every few seconds in both device
In iOS 
Printing description of byteArray:
▿ 13 elements
  - 0 : 195
  - 1 : 4
  - 2 : 1
  - 3 : 213
  - 4 : 130
  - 5 : 0
  - 6 : 0
  - 7 : 64
  - 8 : 2
  - 9 : 152
  - 10 : 178
  - 11 : 213
  - 12 : 130
In Android
Values looks different but these are same if convert them to decimal to hex
                What does the byte array contain? What result do you get and what do you expect? – Also your Java code copies bytes 5..8 and the Swift copies the bytes 7...10 from the array.

                @MartinR I updated question for expected values, Java code copies 5, 6, 7, 8 and Swift copies 7, 8, 9, 10 because byte array length in java is 11 byte and in ios it's 13 byte, I am getting 2 more byte then in android in the beginning so I have to pick value from 7

The byte array contains the big endian representation of a 32-bit
floating point value. You have to convert that to the host byte order
(which is little-endian on all current Apple platforms):
func getUnitValue(byteArray:[UInt8]) -> Float {
    let value = fromByteArray([byteArray[7], byteArray[8], byteArray[9], byteArray[10]], UInt32.self)
    return Float(bitPattern: UInt32(bigEndian: value))
let array: [UInt8] = [195, 4, 1, 213, 130, 0, 0, 64, 2, 152, 178, 213, 130]
print(getUnitValue(byteArray: array)) // 2.0405587
