How can I get strings from array object

Question

I am new in IOS, I get this response from backend

Optional([["contact_name": phone, "verified": <null>, "id": 22033, "entity_id": 1111, "verification_data": <null>, "entity": Recruiter, "view_scope": <null>, "contact_value": 0987654321]])

I need "contact_value" string from object.How can I get?

@JoakimDanielson no, it's an array of dictionaries, note double square brackets — mag_zbc

I think what OP should do regardless is to read about collections in The Swift Programming Language. This is an excellent source if you're new to Swift (and also more experienced) to learn the basics of the language. It's also available as an iBook. Much recommended — Joakim Danielson

@RealmOfFire Did you read some basics in Swift language? see here developer.apple.com/documentation/swift/dictionary — Mani

let array: [[String: Any]] = [["contact_name": "John", "verified": true, "id": 22033, "entity_id": 1111, "verification_data": "", "entity": "Recruiter", "view_scope": "", "contact_value": 0987654321]]

for item in array {
    let contactName = item["contact_name"] as? String
    print(contactName ?? 0)
}

This is just a basic for/loop to extract the data, but there are a lot of better ways to accomplish this stuff depending on how your code is implemented.

@mag_zbc I was just trying to show a simple for/loop and grabing the data. I updated the array to complile

Could you fix your answer so it reads the right key. Right now you're typecasting a String value to an Int.

Instead of normal for-loop, try map concept. Note: This is tested code.

let arrayOfDict: [[String: Any]] = [["contact_name": "phone", "verified": "", "id": 22033, "entity_id": 1111, "verification_data": "", "entity": "Recruiter", "view_scope": "", "contact_value": 0987654321]]

let arraOfCtcName : [Int] = arrayOfDict.map({ (element) in
            let value = element["contact_value"]
            return (value != nil && value is Int) ? value as! Int : 0
        })

You could as well go a little more functional, if all you want is contact_value,

let contactValues = a.flatMap { $0 }?
    .map { $0["contact_value"] ?? 0 } as? [Int]

let arrayOfDict: [[[String: Any]] = ["contact_name": "phone", "verified": <null value>, "id": 22033, "entity_id": 1111, "verification_data": <null value>, "entity": "Recruiter", "view_scope": <null value>, "contact_value": 0987654321], ....]

var arrayContact = [Any]()

for dict in arrayOfDict {

  if let contactValue = dict["contact_value"] as? String { //as String
    arrayContact.append(contactValue)
  } else if let contactValue = dict["contact_value"] as? Int { //as Int
    arrayContact.append(contactValue)
  }
}

print(arrayContact)
