@IBOutlet weak var mainImage: UIImageView! 



@IBOutlet weak var amountOfCreditInGame: UILabel! 
@IBOutlet weak var usersCredits: UILabel! 
@IBOutlet weak var progressBar: UIProgressView! 

var usersCredit = 0 { 
    didSet{ 
     usersCredits.text = "Credit: \(credit)" 
    }} 

    var creditInGame = 0 { 
    didSet{ 
     amountOfCreditInGame.text = "Credits in: \(creditInGame)" 
     }} 


var gameProgress: Float = 1000.0 



var credit = 0 { 
    didSet { 
     creditLabel.text = "Credit: \(credit)" 
    } 
} 

override func viewDidLoad() { 
    super.viewDidLoad() 

    self.gameProgress = 0 
    self.progressBar.progress = 0 
} 

override func didReceiveMemoryWarning() { 
    super.didReceiveMemoryWarning() 

} 


@IBAction func addMoreCredits(_ sender: Any) { 
    creditInGame += 1 + credit 

    self.gameProgress += 1 



    if self.gameProgress == 1 { 
     self.progressBar.progress = 1000.0 
     return 
    } 
    self.progressBar.progress = gameProgress 

}

而不是试图设置进度条的进度，你应该做的是除以1000的gameProgress，所以1/1000这将完成是返回因为进度条的最小值为0.0，最大值为1.0的事实，因此可以应用于进度条的小数部分。
