i do not understand at all...

So i am trying to iterate through my array of players, and then i want to assign them to 2 variables. experienced, and unexperienced players.

But i cant get it to work, i think its because i need to somehow unwrap the values of the player in the array players?

Anyways, i have been trying for 2 days now without getting any further, i looked through the community without much luck. and now i just hope someone can guide me in the right direction...

Thanks!

Hey

Struggled to figure this one out, however you could create the players as objects and then create a func that checks if the player object is experienced and then return that player:

Like so 

import UIKit
class Player {

    let name: String
    let height: Int
    let experience: Bool
    let guardians: String
    let explayers: [Player] = []

    init(name: String, height: Int, experience: Bool, guardians: String) {
        self.name = name
        self.height = height
        self.experience = experience
        self.guardians = guardians

    }



}


let joeSmith = Player(name:"Joe Smith", height: 42, experience: true, guardians: "Jim and Jan Smith")
let billBon = Player(name: "Bill Bon", height: 36, experience: true, guardians: "Clara Tanner")
let sammyAdams = Player(name: "Sammy Adams", height: 45, experience: false, guardians: "Jeff Adams")


let players = [joeSmith,  billBon, sammyAdams]

func isExperienced() {

    for x in players {
        if x.experience == true {
            print(x.name)
        } else {
            print ("Oh no")
        }
    }
}

isExperienced()

hope thats helps

Hi thanks for the answer, im afraid im not allowed to use classes yet, but i actually found another way to do it. But here comes the next question:

how do i append the player to the array, instead of the dictionary values of the player? :D 

let players: [[String: Any]] = [joeSmith, jillTanner, billBon, evaGordon, mattGill, kimmyStein, sammyAdams, karlSaygan, suzaneGreenberg, salDali, joeKavalier, benFinkelstein, diegoSoto, chloeAlaska, arnoldWillis, phillipHelm, lesClay, herschelKrustofski]


// collections of experienced/unexperienced players

var experiencedPlayers: [[String: Any]] = []   //I am trying to get the names in this array just like in the players array?
var unexperiencedPlayers: [[String: Any]] = []

// Collections of players in each team

var teamSharks: [[String: Any]]
var teamDragons: [[String: Any]]
var teamRaptors: [[String: Any]]

// Team creator


players
for player in players {
    var index = 0
    switch player["Experience"] as? Bool {
    case true?: experiencedPlayers.append(player)  // this is where it goes wrong, it appends the values inside the dictionary instead of just [joeSmith, jillTanner etc..]
    default: print("OH NO!")
    }
    index += 1
}

do you know what to do?
