How to convert HEX string to UInt16?

I have a HEX string d285 and I want to convert it UInt16, please guide me how I can convert it. I tried this 

let buffer = UInt16("\(UInt8(text, radix: 16)!)")
return Data(bytes: (buffer?.bigEndian.toBytes)!)

but it's not working

Solution

  • UInt16 has an initializer that takes a string and radix value. This can be used to create UInt16 from string.

    let hexString = "d285"
let hexToInt = UInt16(hexString, radix: 16) // prints 53893
