This is my code of the json object. I'm trying to get an image dictionary into the images value. I've tried a lot of things and maybe I'm missing something.
let jsonObject: [String: Any] = [
"name_space": "users",
"data_collection": "data://brownfosman5000/DatFace/",
"action" : "add_images",
"images": []
]
I have created a json dictionary to hold the images
let imageDictionary = try! JSONSerialization.jsonObject(with: imageJSON, options: []) as! [String : Any]
I have also created an array to hold the array of imageDictionaries
let images:NSMutableArray = NSMutableArray()
self.images.add(imageDictionary)
How can I add the images array to the array in my json as a dictionary? Everything prints out nice I just need to add it to the json.
First of all never use NSMutable...
collection types in Swift. Use a native type with the var
keyword
var images = [[String:Any]]()
Second of all make jsonObject
also mutable
var jsonObject: [String: Any] = [ ...
Append the dictionary to images
images.append(imageDictionary)
Assign the array to the dictionary for key images
jsonObject["images"] = images
