create a dictionary from json data values - ios

Question

I'm trying to create a dictionary from 2 json values, so far I can get one and append to an array but instead I would like to combine 2 values as a dictionary and add them to an array. This is what my function currently looks like:
var menuButtonsArray: [String?] = []
func getAppMenuButtons() {
guard let appJSON = appMenuJSON else {return}
guard let items = appJSON["items"] as? [[String: Any]] else {
return
}
let filteredItem = items.filter{$0["itemId"] as! String == "Items"}[0]
if let data = filteredItem["data"] as? [[String:Any]] {
for embeddedDict in data {
for (key, value) in embeddedDict {
if key == "name" {
menuButtonsArray.append(value as! String)
print("key: \(value)")
}
}
}
}
}
This is what the json looks like, it's shortened to fit this post:
"itemId": "Items",
"data": [
{
"name": "Item1",
"url": "www.item1.com"
},
{
"name": "Item2",
"url": "www.item2.com"
},
{
"name": "Item2",
"url": "www.item2.com"
}
]
What I'm trying to do is create an array of dictionaries with the format:
name:url
so something like :
["item1":"www.item1.com","item2":"www.item2.com", "item3":"www.item3.com"]

Answer 1

Here is an example on how you can use map() get the array you want:
var data = [["name": "Item1","url": "www.item1.com"],
["name": "Item2","url": "www.item2.com"],
["name": "Item3","url": "www.item3.com"]]
var newData = data.map { (dict: Dictionary) -> Dictionary<String, String> in
return [dict["name"]!:dict["url"]!] }
This code should give you
[ ["Item1": "www.item1.com"], ["Item2": "www.item2.com"], ["Item3":
"www.item3.com"] ]
as output

First of all if you need a Dictionary then declare your result as Dictionary instead of Array, you can use subscribe to use your embeddedDict["name"] as key in your resultDictionary and your embeddedDict["url"] as your resultDictionary value
func getAppMenuButtons() {
guard let appJSON = appMenuJSON else {return}
guard let items = appJSON["items"] as? [[String: Any]] else {
return
}
let filteredItem = items.filter{$0["itemId"] as! String == "Items"}[0]
var resultDict : [String:String] = [:]
if let data = filteredItem["data"] as? [[String:Any]] {
guard embeddedDict["name"] != nil && embeddedDict["url"] else{
continue
}
for embeddedDict in data {
resultDict[embeddedDict["name"]] = embeddedDict["url"]
}
}
debugPrint(resultDict) //in resultDict you will have your desired result
}
