How

Why use Arrow

Example

Swift Model

structProfile{varidentifier=0varname=""varlink:NSURL?varweekday:WeekDay=.Mondayvarstats=Stats()varphoneNumbers=[PhoneNumber]()}

JSON File

{"id":15678,"name":"John Doe","link":"https://apple.com/steve","weekdayInt" :3,"stats": {"numberOfFriends":163,"numberOfFans":10987    },"phoneNumbers": [{"label":"house","number":"9809876545"                     }, {"label":"cell","number":"0908070656"                     }, {"label":"work","number":"0916570656"    }]}

Before (Chaos)

varprofile=Profile()// Intiflet id=json["id"]as?Int{    profile.identifier= id}  // Stringiflet name=json["name"]as?String{    profile.name= name}// NSURLiflet link=json["link"]as?String, url=NSURL(string:link){    profile.link= link}// Enumif let weekdayInt=json["weekdayInt"]as?Int, weekday=WeekDay(rawValue:weekdayInt){    profile.weekday= weekday}// Custom nested objectif let statsJson=json["stats"]as?AnyObject{iflet numberOfFans=statsJson["numberOfFans"]as?Int{        profile.stats.numberOfFans= numberOfFans}iflet numberOfFriends=statsJson["numberOfFriends"]as?Int{        profile.stats.numberOfFriends= numberOfFriends}}// Array of custom nested objectif let pns=json["phoneNumbers"]as?[AnyObject]{forpnin pns{        phoneNumbers.append(PhoneNumber(json: pn))}}

After 🎉🎉🎉

extensionProfile:ArrowParsable{mutatingfunc deserialize(_ json:JSON){        identifier<--json["id"]        link<--json["link"]        name<--json["name"]        weekday<--json["weekdayInt"]        stats<-json["stats"]        phoneNumbers<--json["phoneNumbers"]}}

Usage

letprofile=Profile()profile.deserialize(json)

Installation

Swift Package Manager

Carthage - Deprecated

github "freshOS/Arrow"

CocoaPods - Deprecated

target 'MyApp'pod 'Arrow'use_frameworks!

How Does That Work

stats<--json["stats"]

//  Stats+Arrow.swiftimport FoundationextensionStats:ArrowParsable{mutatingfunc deserialize(json:JSON){        numberOfFriends<--json["numberOfFriends"]        numberOfFans<--json["numberOfFans"]}}

Flexible you said

stats.numberOfFriends<--json["stats.numberOfFriends"]stats.numberOfFans<--json["stats.numberOfFans"]

Date Parsing

Globally

// Configure Global Date Parsing with one of thoseArrow.setDateFormat("yyyy-MM-dd'T'HH:mm:ssZZZZZ")Arrow.setUseTimeIntervalSinceReferenceDate(true)Arrow.setDateFormatter(aDateFormatter)// Then later dates can be parsed form custom date format or timestamps automatically 🎉letjson:JSON=JSON(["date":"2013-06-07T16:38:40+02:00","timestamp":392308720])date1<--json["date"]date2<--json["timestamp"]

On a per-key basis

createdAt<--json["created_at"]?.dateFormat("yyyy-MM-dd'T'HH:mm:ssZZZZZ")createdAt<--json["created_at"]?.dateFormatter(aCustomDateFormatter)

Accessing JSON values

Nested values

value<--json["nested.nested.nested.nestedValue"]

Object at index

value<--json[12]

Combine both

value<--json[1]?["someKey"]?[2]?["something.other"]

Looping on Array

iflet collection= json.collection{forjsonEntryin collection{        //Do something}}
