how to use SwiftyJSON framework to read a locally declared JSON

I am trying to read a locally declared JSON, since I still do not have the network ready to send me JSON examples for the app we are developing. For some reason I get a null when trying to print the json created by SwiftyJSON framework. This is my class:

import Foundation
import SwiftyJSON
let mockShifts = "{\"numOfShiftsInDay\": 3,\"shifts\": [{\"StartTime\": \"06:30\",\"EndTime\": \"14:00\"},{\"StartTime\": \"14:00\",\"EndTime\": \"19:00},{\"StartTime\": \"19:00\",\"EndTime\":\"01:00\"}]}"
class WeeklySchedule {

var shifts: [Shift] = []
var shiftsAmount: Int = 3
var relative: Int = 0
func setShiftsAmount(amount: Int){
    self.shiftsAmount = amount
    for _ in 1...amount{
        self.shifts.append(Shift())
    }
    getShifts()
}

func getRelative() -> Int{
    return relative
}
func getShifts(){
    let data = mockShifts.data(using: .utf8)!
    let json = JSON(data: data)
    print(mockShifts) //This prints out a JSON that looks OK to me
    print(json)       //This prints NULL
    if let numOfShifts = json["numOfShiftsInDay"].string {
        print(numOfShifts) //This code is unreachable
    }
}
}

And this is my console output, when calling setShiftsAmount() which calls getShifts():

{"numOfShiftsInDay": 3,"shifts": [{"StartTime": "06:30","EndTime": "14:00"},{"StartTime": "14:00","EndTime": "19:00},{"StartTime": "19:00","EndTime":"01:00"}]}

null

Why is my JSON null?

The reason you are getting null for your JSON because your JSON string mockShifts is not contain's valid JSON, there is missing double quote(\") for the EndTime key after 19:00 in the second object of array shifts. Add that double quote and you all set to go.

let mockShifts = "{\"numOfShiftsInDay\": 3,\"shifts\": [{\"StartTime\": \"06:30\",\"EndTime\": \"14:00\"},{\"StartTime\": \"14:00\",\"EndTime\": \"19:00\"},{\"StartTime\": \"19:00\",\"EndTime\":\"01:00\"}]}"
