@IBOutlet var customerDashboardButtons:[NSArray]?

Creates an array of arrays.
Calling customerDashboardButtons!.first will return the first array (the NSArray) in your array (the […] will also create an array)

创建一个数组数组。调用customerDashboardButtons!.first将返回数组中的第一个数组(NSArray)([...]也会创建一个数组)

I suspect you want your customerDashboardButtons to be an array of UIButton’s so you would use

我怀疑你希望你的customerDashboardButtons是一个UIButton的数组,所以你会使用

@IBOutlet var customerDashboardButtons:[UIButton]?

Using customerDashboardButtons!.first here will give you a UIButton. Since the type of the array is UIButton, you don’t have to declare your button as UIButton.

使用customerDashboardButtons!.first here将为您提供UIButton。由于数组的类型是UIButton,因此您不必将按钮声明为UIButton。

  var button = customerDashboardButtons!.first

Will work if you change your array.

如果你改变阵列将会工作。
