Use a for loop to set the titles for buttons

Question

I want to use a for loop to set the titles for the button. What I am currently doing is not working. I thought using indexPath.row was working but it does not. The code is not compelling either. I would think there is a simple solution to implement the array.

         var line = UIButton()
var pen = UIButton()
var graph = UIButton()
var save = UIButton()
var nxt = UIButton()

        let btnTitles = ["line","pen","graph","save","next"]
    var increase = 0.1
    for b in [line, pen, graph,save,nxt] {

        b.setTitle(btnTitles(IndexPath.row), for: .normal)
    }
    

Answer 1

let line = UIButton()
let pen = UIButton()
let graph = UIButton()
let save = UIButton()
let nxt = UIButton()

let buttons: [UIButton] = [line, pen, graph, save, nxt]
let btnTitles = ["line", "pen", "graph", "save", "next"]
for i in 0..<buttons.count {
    let button = buttons[i]
    let title = btnTitles[i]
    button.setTitle(title, for: .normal)
}

// probing code //
buttons.forEach {
    if let title = $0.titleLabel?.text {
       print(title)
    }
}

It prints as follows.

line pen graph save next
