Admob interstitial ad fatal error in iOS9, Swift, SpriteKit game

I'm getting a fatal crash when trying to place an admob interstitial ad in my Swift, SpriteKit, iOS9 game.

I believe I've got the Admob SDK and dependencies set-up properly, via CocoaPods, following the streamlined instructions here: https://developers.google.com/admob/ios/quick-start

My Podfile:

platform :ios, '7.0'
use_frameworks!

source 'https://github.com/CocoaPods/Specs.git'
pod 'Google-Mobile-Ads-SDK', '~> 7.0'

target 'My Project's Name' do

end

Then I follow this guide: https://developers.google.com/admob/ios/interstitial

It's a game, so I put the code in GameViewController.swift (rather than ViewController.swift.) The relevant bits:

import GoogleMobileAds

class GameViewController: UIViewController, GADInterstitialDelegate {

var interstitial: GADInterstitial!

override func viewDidLoad() {
    super.viewDidLoad()

    print("Google Mobile Ads SDK version: " + GADRequest.sdkVersion())

    self.interstitial = createAndLoadInterstitial()

    // unrelated code
    }
}

func createAndLoadInterstitial() -> GADInterstitial {
    var interstitial = GADInterstitial(adUnitID: "ca-app-pub-3940256099942544/4411468910")
    interstitial.delegate = self
    interstitial.loadRequest(GADRequest())
    return interstitial
}


 func interstitialDidDismissScreen(ad: GADInterstitial!) {
    self.interstitial = createAndLoadInterstitial()
}


func gameOver() {
    if self.interstitial.isReady {
        self.interstitial.presentFromRootViewController(self)
    }
}

I get the proper output in console: Google Mobile Ads SDK version: afma-sdk-i-v7.7.0

But I get this error on the gameOver() function:

fatal error: unexpectedly found nil while unwrapping an Optional value

It appears to be on the if self.interstitial.isReady line.

I did make the App Transport Security (ATS) allowance detailed here: https://developers.google.com/admob/ios/ios9

XML looks like:

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSAllowsArbitraryLoads</key>
    <true/>
</dict>

I also tried changing out the ad unit ID from the above (the test code Google has in instructions) with my actual ad ID, but no dice -- same error.

Any suggestions would be appreciated.

Cheers, Kevin

Are you checking that the ad has preloaded correctly and therefore is not nil?

You can also add a check just before the ...isReady line

 guard self.interstitial != nil else { return }

to make sure its not nil.

If you are still stuck I have an ads helper on gitHub you an check out, it includes adMob as well
