Passing an IBOutlet variable to another class

Question

I'm trying to take an IBOutlet of type UITextField, and use that variable in a function with let constants from another class... How would I go about dong this?

Example:

• Class A

  Import UIKit
  
  class ViewController: UIViewController {
      @IBOutlet weak var userInputTextField: UITextField!
      @IBOutlet weak var labelToBeUpdated: UILabel!
  }
  

• Class B

  Import Foundation
  
  class Data {
      let x = 10
      let y = 100
  }
  

I would like to take the userInputTextField in Class A and multiply it by x in Class B, then divide it by y in Class B... (userInput * x) / y

Thanks

Answer 1

Actually you can't multiply IBOutlets like text fields ;-)

• Create an instance of class Data
• Check if the text value of the text field is convertible to Int and do the math by accessing Data's properties.

let data = Data()

if let userInput = Int(userInputTextField.text) {
  let result = (userInput * data.x) / data.y
}
