DataDecoder

Swift Data Decoder. Easily Decode Data values

Installation

DataDecoder is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod "DataDecoder"

Swift Package Manager:

    dependencies: [
        .package(url: "https://github.com/FitnessKit/DataDecoder", from: "5.0.0"),
    ]

Swift4

    dependencies: [
        .package(url: "https://github.com/FitnessKit/DataDecoder", .branch("swift42")),
    ]

How to Use

Example:

let sensorData: Data = Data([ 0x02, 0xFE, 0xFF, 0xEF, 0xBE, 0xAD, 0xDE, 0xA5])

var decoder = DecodeData()
let height = decoder.decodeUInt8(sensorData)
let weight = decoder.decodeUInt16(sensorData)
let deadbeef = decoder.decodeUInt32(sensorData)
let nib = decoder.decodeNibble(sensorData)
//This should come back 0 as there is no more data left
let novalue = decoder.decodeNibble(sensorData)

Example Using Optionals:

let sensorData: Data = Data([ 0x02, 0xFE, 0xFF, 0xEF, 0xBE, 0xAD, 0xDE, 0xA5])

var decoder = DecodeData()

if let height = decoder.decodeUInt8IfPresent(sensorData) {}
let weight = decoder.decodeUInt16IfPresent(sensorData)
let deadbeef = decoder.decodeUInt32IfPresent(sensorData)
let nib = decoder.decodeNibbleIfPresent(sensorData)
// This will be nil as there is no data left
let novalue = decoder.decodeUInt8IfPresent(sensorData)
