How to Print Swift Dictionary into readable format

Question

Here I create a Swift Dictionary.

  var paramDict: [String: String] = [
      "tour_type": "tour",
      "zone_id":   txtRegoin.tag.description,
      "district_from_id" : txtLocationFrom.tag.description,
      "district_to_id" : txtLocationTo.tag.description,
      "start_date" :  selectedStartTime.toString(dateFormat: BBTIMESTAMP_YYYYMMDD),
      "start_time" :  selectedStartTime.toString(dateFormat: BBTIMESTAMP_HH_MM),
    
      "return_date" :  selectedEndTime.toString(dateFormat: BBTIMESTAMP_YYYYMMDD),
      "return_time" :  selectedEndTime.toString(dateFormat: BBTIMESTAMP_HH_MM),
      
      "vehicle_type" : vehicleObjArr[selectedVehicleObj].brand!,
      "capacity" :  (vehicleObjArr[selectedVehicleObj].capacity?.description)!,

      
      "comment" : textDetails.text ?? "",
      "passengers" : numOfPassengers.description

  ]

If I debubg the dictionary.

po paramDict

 ▿ 14 elements
      ▿ 0 : 2 elements
        - key : "passengers[0]"
        - value : "27785"
      ▿ 1 : 2 elements
        - key : "zone_id"
        - value : "1"
      ▿ 2 : 2 elements
        - key : "return_time"
        - value : "13:20"
      ▿ 3 : 2 elements
        - key : "start_date"
        - value : "2020-07-01"
      ▿ 4 : 2 elements
        - key : "start_time"
        - value : "13:20"
      ▿ 5 : 2 elements
        - key : "capacity"
        - value : "7"
      ▿ 6 : 2 elements
        - key : "district_from_id"
        - value : "1"
      ▿ 7 : 2 elements
        - key : "return_date"
        - value : "2020-07-02"
      ▿ 8 : 2 elements
        - key : "tour_type"
        - value : "tour"
      ▿ 9 : 2 elements
        - key : "passengers"
        - value : "7"
      ▿ 10 : 2 elements
        - key : "district_to_id"
        - value : "3"
      ▿ 11 : 2 elements
        - key : "vehicle_type"
        - value : "Sedan"
      ▿ 12 : 2 elements
        - key : "comment"
        - value : "Ads adds"
      ▿ 13 : 2 elements
        - key : "passengers[1]"
        - value : "23132"

This is not well readable format. Especially if you send this dictionary to your backend developer.ie. I am facing a post problem and multiple times gave my dictionary which printed on debug mode. Its not good readable formatted output.

So, How it possible to good looking readable format?

And what is a good format? The above output is readable so why would it be an issue to another developer? — Joakim Danielson, Jun 30 '20 at 09:24
Does this answer your question?

This is how you print a more readable format of dictionary. If you want to debug

(lldb) po print(paramDict as NSDictionary)
{
    capacity = 5;
    comment = Assad;
    "district_from_id" = 1;
    "district_to_id" = 1;
    "employees[0]" = 59903;
    passengers = 2;
    "return_date" = "2020-07-10";
    "return_time" = "14:34";
    "start_date" = "2020-07-08";
    "start_time" = "14:34";
    "tour_type" = tour;
    "vehicle_type" = Sedan;
    "zone_id" = 1;
}

Or

Normal Print

print(paramDict as NSDictionary)

Simply use print(_:) in the console like so,

po print(paramDict)

`paramDict.description` will print in the `String` format including the escape characters. Example: `"[\"tour_type\": \"tour\"]"` – PGDev Jun 30 '20 at 09:35
