Hello everyone,
I am a beinner and am learning swift from the apple e-book. I have been doing the apple pie project and am getting this error.I checked all the connections, they seemed alright.
my code is as follows:
view Controller:
< class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
/
newRound()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
/
}
@IBOutlet weak var treeImageView: UIImageView!
@IBOutlet weak var correctWordLabel: UILabel!
@IBOutlet weak var scoreLabel: UILabel!
@IBOutlet var letterButtons: [UIButton]!
@IBAction func buttonPressed(_ sender: UIButton) {
sender.isEnabled = false
let letterString = sender.title(for: .normal)!
let letter = Character(letterString.lowercased())
currentGame.playerGuessed(letter: letter)
updateUI()
}
var listOfWords = ["buccaneer", "swift", "glorious", "incandescent", "bug", "program"]
let incorrectMovesAllowed = 7
var totalWins = 0
var totalLosses = 0
var currentGame: Game!
func newRound(){
let newWord = listOfWords.removeFirst()
currentGame = Game(word: newWord, incorrectMovesRemaining: incorrectMovesAllowed, guessedLetter: [])
updateUI()
}
func updateUI() {
scoreLabel.text = "Wins: \(totalWins), Losses: \(totalLosses)"
treeImageView.image = UIImage(named: "Tree \(currentGame.incorrectMovesRemaining)")
}
} >
file named Game.swift includes:
<
struct Game{
var word: String
var incorrectMovesRemaining: Int
var guessedLetter: [Character]
mutating func playerGuessed (letter: Character){
guessedLetter.append(letter)
if !word.characters.contains(letter){
incorrectMovesRemaining -= 1
}
} >
The error im getting is:
