        }else{
            NSLog("fail")
        }

Could not cast value of type '__NSArrayI' (0x1059da8b0) to 'NSString' (0x103a50b20).

Answer 1

try this

let Namelist = [["name" : "daniel", "email" : "abc@gmail.com"]]

let data = Namelist.filter{($0 as [String:String])["name"]!.lowercaseString.containsString("daniel".lowercaseString)}.map { x in return x["email"]!}
print(data)

I have tested it in playground

You have a dictionary array that means that you need to loop through the array and then check if each dictionary contains a value for the key 'name' that is equal to your nameLabel text and then get the email from the same dictionary.

let nameList : NSMutableArray = [["name":"daniel","email":"daniel@test"], ["name":"martin","email":"martin@test"], ["name":"john","email":"john@test"]]

...
let nameLabel = UILabel()
nameLabel.text = "daniel"
...

for list in nameList {

    if let dic = list as? [String: String] {


        if dic["name"] == nameLabel.text {
            let email = dic["email"]
            print("\(email)")
        }
    }
}
