不能用 '()' 类型的索引下标 '[UIImage]' 类型的值

Question

我一直收到此错误：

不能将类型为"[UIImage]"的值下标为"((" 的索引

这是我的代码：

let images: [UIImage] = [
    UIImage(named: "profilePicture.jpg")!,
    UIImage(named: "back3.jpg")!,
    UIImage(named: "back1.jpg")!]
var index = 0
let animationDuration: TimeInterval = 0.25
let switchingInterval: TimeInterval = 3
let chnagingImageView = UIImageView()
override func viewDidLoad() {
    chnagingImageView.frame = CGRect(x: 0, y: 300, width: view.frame.width, height: 200)
    view.addSubview(chnagingImageView)
    chnagingImageView.image = images[index += 1]
    animateImageView()
}

错误发生在以下行中：

chnagingImageView.image = images[index += 1]

任何帮助将不胜感激。请注意，我看到了另一个问题，这只是游乐场的问题，它提供的解决方案只是刷新代码。但是，这不起作用，我仍然收到错误。

 let images: [UIImage] = [
        UIImage(named: "profilePicture.jpg")!,
        UIImage(named: "back3.jpg")!,
        UIImage(named: "back1.jpg")!]
    var index = 0
    let animationDuration: TimeInterval = 0.25
    let switchingInterval: TimeInterval = 3
    let chnagingImageView = UIImageView()
    override func viewDidLoad() {
        chnagingImageView.frame = CGRect(x: 0, y: 300, width: view.frame.width, height: 200)
        view.addSubview(chnagingImageView)
    for myimage in images.count-1
     { 
      if myimage==1 
     { 
    chnagingImageView.image = images[myimage] 
     } 
    } 
       }

将其更改为

 index += 1
 chnagingImageView.image = images[index]

因为index += 1返回() =>数组无法获取索引类型为 ()
