This library contains a collection of helper methods for byte manipulation in Swift. It requires Swift 5.
If you're like me, and can never remember whether you should double right-shift or tripple left-shift to get to the bits you want, then this library might be of some use to you.
// Let's say we have an interesting 64 bit number:
let largeNumber: UInt64 = 0xF00FA00AB00BC00C
// Extracting the fifth byte, the hard way:
let fifthByte = UInt8((largeNumber >> 24) & 0xFF)
// Extracting the fifth byte using this library:
let fifthByte = bytes(largeNumber)[4]All available byte manipulation methods can be found in the Bytes.swift file.
The BytesTests.swift file contains examples of their use.
You can use CocoaPods to add this library to your project. Use the following
in your Podfile:
pod 'SwiftBytes'After adding this library to your project, you can import it in your swift files:
import SwiftBytes
