@IBOutlet var dataPickers: [UIPickerView]! {
  didset {

  }
}

The problem is, i have to say that if the first member of dataPickers do that things, but I don't know how I can say that in the didset.

The didSet is called when the whole array is set. If you want to apply properties to just the first picker in the array, then you can do something like:

@IBOutlet var dataPickers: [UIPickerView]! {
    didSet {
        if let first = dataPickers.first {
            first.someProperty = someValue
        }
    }
}
