Construct a JSON payload with list of strings in swift

Question

I would construct the below payload dynamically for a POST service call. I am not sure how to create a list of strings in dictionary

{
    "Id":"2025",
    "deviceType": "iphone",
    "category": ["Dental", "Vision"] 
}

My code

var categoryList = ["Dental", "Vision"]
let json = ["Id": "2025", "deviceType": "iphone", "category": categoryList] as! Dictionary<String, String>     
let jsonData = try? JSONSerialization.data(withJSONObject: json)

you can do like this:-

and no need to onvert json into data you can directly post this json in SERVICE CAll as a parameter

let jsonToSend:[String:Any] = [
    "Id":"pass your id here",
    "deviceType":"device type here",
    "category":"category array here"
]
