Cannot assign to property: 'popupHeight' is a get-only property

Question

I got problems using this cocoapod .

I want to set the popupHeight for the popup, but it says "Cannot assign to property: 'popupHeight' is a get-only property"...

This is my code:

@IBAction func testBtnPressed(_ sender: Any) {
    guard let popupVC = storyboard?.instantiateViewController(withIdentifier: "popup") as? BottomPopupViewController else { return }
    popupVC.popupHeight = 50.0 //ERROR!!!
    popupVC.popupDelegate = self
    present(popupVC, animated: true, completion: nil)
}

Can someone help me? Thanks!

I just checked the link and the sample project. In sample project I can see that they have overridden named as popupHeight on which you are trying to set a value like this:- override var popupHeight: CGFloat { return height?? CGFloat(300) } override var popupHeight: CGFloat { return height?? CGFloat(300) } you can lear more about the get and sethere .

For now what you can do is simply in your BottomPopupViewController you can simply override this popupHeight variable and set the value which you want. or else you can do in similar way they have done in the example.

For that:- take a variable named height or any thing you want like this:- var height: CGFloat? and then set it while instantiating your View controller like this:- popupVC.height = 50.0 and have the overriden method in your BottomPopupViewController this one:- override var popupHeight: CGFloat { return height?? CGFloat(300) } override var popupHeight: CGFloat { return height?? CGFloat(300) } basically it would take the height you will be setting in here popupVC.height = 50.0
