Right now I have a button at the cart, now the button can be clicked even if theres nothing added to the cart.... how do i edit my code to allow the button to be clicked only if something is added to the cart?

Context: once a course is selected from the main menu, it will be added to the second tab "the cart" and theres a "enroll courses" button which label will change to "successfully enrolled" upon being tapped on.

My code right now is

@IBAction func coursesEnrolledAction(_ sender: UIButton){ enrollCourses.setTitle("Successfully Enrolled ✔️", for: .normal) }

Use the .disabled Button modifier, with a suitable condition for when there is nothing in the cart - like this.
