Array Iteration closure with index in swift -iOS [duplicate]

I am wondering Is there a shortcut to make the code following simple?

• Index are getting from Foreach closure instead of auto-increment set by myself (any keyword provide by library)?

• Passing "index" into my onSectionSelected as an argument?

  var index = 0
  [view_a, view_b, view_c, view_d].forEach{
      $0?.isUserInteractionEnabled = true
      $0?.tag = index
      index += 1
      let tapGesture = UITapGestureRecognizer(target: self, action: #selector(onSectionSelected))
      $0?.addGestureRecognizer(tapGesture)
  }
  
  func onSectionSelected() {
      //do something for touchUpInside event
  }
  

Emphasise that I clearly understand how to use (index, value), array. enumerated to express this. Please answer accordingly.
