Append to array from multiple textFields?

I have a bunch of textFields which content I want to add to a array
I have tried different approaches, and I got it working with this method: 

@IBAction func addToArrayTapped(_ sender: UIButton) {

        if let fromTextField1 = textField1.text {
            array.append(fromTextField1)
        }
        if let fromTextField2 = textField2.text {
            array.append(fromTextField2)
        }
        if let fromTextField3 = textField3.text {
            array.append(fromTextField3)
        }
        print(array) 
}

Is this really the correct way to add content from a textField to a array? It feels a bit complicated.

There is an easy way:


    // Here you can use IBOutlet collection or form textFields array programmatically
    let textFields = [textField1, textField2, textField3] 
    let result = textFields.compactMap { $0.text }

And no force unwraps. Type of result is [String].

You can do

let arr = [textField1,textField2,textField3].map { $0.text! }

Also you can create outlet collection for all textfields in IB like

@IBOutlet weak var allTextF:[UITextField]!

instead of individually hooking each one
