收到错误消息：“扩展名可能不包含存储的属性”

Question

I am new in Swift and xcode. I am trying to declare a GoogleMobileAds variable inside a UISplitViewControllerDelegate , but I am getting an error: Extensions may not contain stored properties.

Here is my code:

import GoogleMobileAds

extension MainBiblePagerVC: UISplitViewControllerDelegate{
    // Setup Navigation Items in Bible Page
    var interstitial: GADInterstitial!

Thanks!

Answer 1

You can't declare stored properties inside extension, only computed ones

So you have two ways:

1. declare stored property inside your class MainBiblePagerVC

2. use computed property:

    extension MainBiblePagerVC: UISplitViewControllerDelegate{ var interstitial: GADInterstitial! { // add object initialization here let object = GADInterstitial() // set its parameters return object } }
