How to convert Any to Int in Swift

Question

I get an error when declaring i

var users =  Array<Dictionary<String,Any>>()
users.append(["Name":"user1","Age":20])
var i:Int = Int(users[0]["Age"])

How to get the int value?

Answer 1

var i = users[0]["Age"] as Int

As GoZoner points out, if you don't know that the downcast will succeed, use:

var i = users[0]["Age"] as? Int

The result will be nil if it fails

Answer 2

Swift 4 answer :

if let str = users[0]["Age"] as? String, let i = Int(str) {
  // do what you want with i
}
