To create key value pairs according to user input in an array in swift

I need to create an array of key-value pairs to a key "availabilities" according to user inputs in the following format to post the data. Confused about how to do that.

"availabilities"

"availabilities": [

"availabilites_start_time": "6:00",
"availabilites_end_time": "10:00",
"availabilites_dayofweek": "1.",
"availabilites_shift": "Morning"

],

Hope this will helps:

var availabilitiesDict = [String: Any]()
availabilitiesDict["availabilities"] = [["availabilites_start_time" : "6:00", "availabilites_end_time": "10:00", "availabilites_dayofweek" : "1.", "availabilites_shift" : "Morning"]]

let jsonData = try? JSONSerialization.data(withJSONObject: availabilitiesDict, options: )
let jsonString = String(data: jsonData!, encoding: .utf8)!
print(jsonString)


First of all create a Struct as a data model and one array as data source as shown in below code.

struct Availabilities
let availabilites_start_time, availabilites_end_time, availabilites_dayofweek, availabilites_shift : String


var availabilitiesArray = [Availabilities]()


We get memberwise initializers for free, so whenever user Picks his choices create an instance of Availabilities with those values as shown in below code snippet.

let availability = Availabilities (availabilites_start_time: "6:00", availabilites_end_time: "10:00", availabilites_dayofweek: "1", availabilites_shift:"Morning" )


Since you have a codable type struct, you can use JSONEncoder to convert your type to Data which can be either written to a file or sent over the network.

let jsonEncoder = JSONEncoder()
let jsonData = try jsonEncoder.encode(availability)

let jsonString = String(data: jsonData, encoding: .utf8)
print(jsonString)


I will suggest 1st create the inside array of dictionary then outside dictionary.

var myData = [String:Any]()
var dataArray = [[String:Any]]()
var finalDict = [String : Any]()

myData["availabilites_start_time"] = "6:00"
myData["availabilites_end_time"] = "10:00"
myData["availabilites_dayofweek"] = "1."
myData["availabilites_shift"] = "Morning"

dataArray.append(myData)
finalDict["availabilities"] = dataArray

print(finalDict)

let jsonData = try? JSONSerialization.data(withJSONObject: finalDict, options: )
let jsonString = String(data: jsonData!, encoding: .utf8)!
print(jsonString)
