AI-generated Key Takeaways
-  Migrating to version 12.0.0 of the Google Mobile Ads SDK for iOS requires upgrading to Xcode 16.0 and includes significant changes to Swift naming conventions, including class prefix removals and renames, to align with Swift API Design Guidelines. 
-  Version 11.0.0 of the Google Mobile Ads SDK for iOS increases the minimum deployment target to iOS 12 and requires a minimum Xcode version of 15.1, and ads will only serve on devices running iOS 13 and higher. 
-  Migrating from version 10 to 11 involves removing the GoogleAppMeasurement dependency, changes to full-screen ad presentation, removal of specific methods and properties, and changes to GADAdLoader error handling and testing behavior. 
-  Version 10.0.0 of the Google Mobile Ads SDK for iOS no longer serves ads on iOS 11 and requires disabling bitcode to integrate the SDK. 
-  Migrating from version 9 to 10 stops ad serving on iOS 11, removes certain types and properties related to user information, and deprecates specific mediation protocols. 
-  Version 9.0.0 of the Google Mobile Ads SDK for iOS stops ad serving on iOS 10, enforces stricter status bar controls for full-screen ads, renames the adDidPresentFullScreenContent:delegate method, and removes the location setting API onGADRequest.
-  Version 8.0.0 of the Google Mobile Ads SDK for iOS introduces unified full-screen ad APIs with static load methods and separate load and presentation events, removes the legacy GADRewardedBasedVideoAdAPI, deprecates smart banners in favor of adaptive banners, and removes thewillLeaveApplicationcallback.
-  Migrating from version 8 to 9 involves deprecating custom event interfaces and providing corresponding mediation adapter APIs and delegate methods to achieve the same functionalities.

Class prefix changes
The following changes have been made to the class prefixes:
- Removed the GADprefix across names for all types.
- Renamed the GAMprefix toAdManager.
- Renamed the GADMprefix toMediation.
Resolve errors
The best way to resolve errors resulting from these changes is to make a Fix-It correction .
Resolve naming conflicts
To resolve naming conflicts, use the namespace provided by the module. For
example, GADRequest 
is now named Request 
. The following example namespaces

API changes to controlling video mute state
The isMuted 
property and setMute: 
method on GADVideoController 
are
replaced with a muted 
property.
Changes to inline adaptive ads
To optimize space utilization, inline adaptive ads initially occupy no space
in the frame. Calling  CGSizeFromGADAdSize(_:) 
 
with
an inline adaptive ad size now returns 0 
height until the Google Mobile Ads
SDK returns an ad.
Removed custom search ads
The following classes are removed with no replacement:
-  GADDynamicHeightSearchBannerView
-  GADDynamicHeightSearchRequest
-  GADSearchBannerView
Changes to error codes
The following error codes have been changed:
| Class | Notes | 
|---|---|
| GADErrorMediationNoFill | Errors now return as GADErrorNoFill. | 
| GADErrorReceivedInvalidResponse | Has been replaced with GADErrorReceivedInvalidAdString. | 
Removed GADSimulatorID
Removed GADSimulatorID 
. Simulators are already in test mode by default.
Changes to custom targeting
The customTargeting 
dictionary on GADRequest 
now uses Any 
instead of String 
as the value type. This lets you pass numerical values to the API.
Changes to extras parameters
- Passing the max_ad_content_ratingkey intoadditionalParametersis no longer supported. To set a maximum ad content rating, see ad content filtering .
Migrate from v10 to v11
Minimum deployment target
The minimum deployment target has been increased to iOS 12.
Minimum Xcode version
The minimum supported Xcode version has been increased to 15.1.
Ads stop serving on iOS 12
Google Mobile Ads SDK version 11.0.0 serves ads only on devices running iOS 13 and higher.
Removed GoogleAppMeasurement dependency
In version 11.0.0, the dependency on  GoogleAppMeasurement 
 
has been
removed. This dependency that powered the user metrics toggle in AdMob will be discontinued 
in early 2024. To
continue collecting user metrics in AdMob, link your AdMob app to Firebase 
and
integrate the Google Analytics for Firebase 
SDK into
your app.
Changes to full-screen ad presentation
The following changes affect the various ad formats:
- App open
- Interstitial
- Rewarded
- Rewarded interstitial
The view controller parameter in -canPresentFromRootViewController:error: 
and -presentFromRootViewController: 
is nullable. If nil is passed, the ad is
presented from the topmost view controller in the view controller hierarchy.
Methods removed
The following methods are removed.
load(withAdUnitID adUnitID: String, request: GADRequest?, orientation: UIInterfaceOrientation) 
willBackgroundApplication() 
willBackgroundApplication()

tag(forChildDirectedTreatment childDirectedTreatment: Bool) 
Properties removed
The following properties are removed.
Removed GADAdFormatUnknown
Removed GADAdFormatUnknown 
with no replacement.
Changes to logging SDK version
Version 11.0.0 removes sdkVersion 
. To log Google Mobile Ads SDK version,
use  versionNumber 
 
instead.

Changes to GADAdLoader error handling
Starting in version 11.0.0, GADAdLoader 
doesn't make an ad request if its  delegate 
 
doesn't conform to the requested ad types' delegate protocol. Previously, it
failed after the ad request was made.
Changes to testing behavior
See the table which shows the updated conditions for when the following
properties return true 
.
- The device is explicitly declared as a test device in testDeviceIdentifiers.
- The device is explicitly declared as a test device in testDeviceIdentifiers.
- The device is a simulator.
- The device is explicitly declared as a test device in the AdMob UI.
Migrate from v9 to v10
Ads stop serving on iOS 11
Google Mobile Ads SDK version 10.0.0 serves ads only on devices running iOS 12 and higher.
Upgrading to Google Mobile Ads SDK version 10.0.0 will not break your app on iOS 11 and iOS 10 devices, however, no ads will be served on those devices.
Building with bitcode is no longer supported
Disabling bitcode in your mobile apps is now required to integrate the Google Mobile Ads SDK.
Types removed
Properties removed
The following properties are removed with no replacement.
Migrate from v8 to v9
Ads stop serving on iOS 10
The minimum iOS version Google Mobile Ads SDK version 9.0.0 supports is iOS 11.
Upgrading to Google Mobile Ads SDK version 9.0.0 will not break your app on iOS 10 devices, however, no ads will be served on those devices.
Stricter enforcement of status bar controls
Starting from version 9.0.0, when you present full-screen format ads, your app should ensure that the ads are able to control the presentation of the status bar. You will see an error message in the logs if you fail to do so.
Depending on the specific layout of view controllers in your app, you might not
need to make any changes to ensure this. Consider whether you need to set the  childViewControllerForStatusBarHidden 
 
property on your ad's rootViewController 
.
Rename adDidPresentFullScreenContent: to adWillPresentFullScreenContent:
There is no behavior change. The delegate method is invoked right before the ad is about to be presented, so the new method name better reflects its functionality.
Remove location setting API on GADRequest
 - (void)setLocationWithLatitude:longitude:accuracy: 
has been deleted from GADRequest 
since location data is not used by Google to target ads. Use
third-party APIs to provide the information to third-party ad networks if
required.
Custom event interfaces deprecation
Custom events enable publishers using AdMob Mediation to add waterfall mediation for an ad network that isn't one of the supported ad networks .
All the custom event protocols are deprecated. Instead, use the existing  GADMediationAdapter 
 
and  GADMediationAdEventDelegate 
 
protocols to achieve the same functionalities. This change improves clarity and
enables you to create custom events for rewarded ads and interscroller ads which
were not previously available.

Google Mobile Ads SDK version 8.0.0 introduces a few major changes as well as some renames and removals of APIs.
Full-screen format API updates
Starting with version 8.0.0, interstitial and rewarded ads share a generic full screen ad style for more consistency. These new full-screen ad APIs have two major distinctions from the version 7 full-screen ad APIs:
-  Static class method load.The previous approach to load/show a full-screen ad is as follows: - Create an ad object instance and hold a reference to it.
- Assign a delegate that handles load and show callbacks.
- Load an ad.
- Check if ad is loaded using isReady.
- Show the ad.
 In version 8, the approach changes slightly. Load callbacks are no longer part of a delegate. Instead, they're passed into the loadmethod as a completion handler:- Call a static load method on the ad class and provide a load completion handler.
- In the load completion callback, keep a reference to the loaded ad that's returned.
- Assign a delegate that handles show callbacks.
- Show the ad.
 The new approach provides these benefits: - You won't ever have a reference to an ad that is not loaded.
- You don't have to hold onto an ad object while it's loading.
 
-  Consistent ad events. Event typeExisting APIv8 APILoad eventsGADInterstitialDelegateorGADRewardedAdDelegateGADInterstitialAdLoadCompletionHandlerorGADRewardedAdLoadCompletionHandlerPresentation eventsGADFullScreenContentDelegatePreviously, to listen for any ad events, you would register a class that implements the GADInterstitialDelegateprotocol to an interstitial's delegate property, or register a class that implements theGADRewardedAdDelegateprotocol to a rewarded ad's delegate property depending on which format you're using. This same delegate had methods related to both the loading and presentation life cycle of an ad.With version 8, load and presentation events are separate. You can now register a GADFullScreenContentDelegateany time prior to showing an ad instead of being required to set a single delegate prior to loading the ad. Ad load events, which are specific to each format, move to a single load completion handler passed in the load method.
Interstitial
Load ad
The code snippets below show you how to load an interstitial ad and listen for events when the ad succeeds or fails to load.
v7
Swift
import GoogleMobileAds import UIKit class ViewController : UIViewController , GADInterstitialDelegate { var interstitial : GADInterstitial ! override func viewDidLoad () { super . viewDidLoad () interstitial = GADInterstitial ( adUnitID : "ca-app-pub-3940256099942544/4411468910" ) interstitial . delegate = self let request = GADRequest () interstitial . load ( request ) } /// Tells the delegate an ad request succeeded . func interstitialDidReceiveAd ( _ ad : GADInterstitial ) { print ( "Interstitial ad loaded." ) } /// Tells the delegate an ad request failed . func interstitial ( _ ad : GADInterstitial , didFailToReceiveAdWithError error : GADRequestError ) { print ( "Interstitial ad failed to load with error: \(error.localizedDescription)" ) } }
Objective-C
@import GoogleMobileAds ; @import UIKit ; @interface ViewController ()@property ( nonatomic , strong ) GADInterstitial * interstitial ; @end @implementation ViewController - ( void ) viewDidLoad { [ super viewDidLoad ]; self . interstitial = [[ GADInterstitial alloc ] initWithAdUnitID : @"ca-app-pub-3940256099942544/4411468910" ]; self . interstitial . delegate = self ; GADRequest * request = [ GADRequest request ]; [ self . interstitial loadRequest : request ]; } /// Tells the delegate an ad request succeeded. - ( void ) interstitialDidReceiveAd: ( GADInterstitial * ) ad { NSLog ( @"Insterstitial ad loaded." ); } /// Tells the delegate an ad request failed. - ( void ) interstitial: ( GADInterstitial * ) ad didFailToReceiveAdWithError :( GADRequestError * ) error { NSLog ( @"Interstitial ad failed to load with error: %@" , [ error localizedDescription ]); } 
v8
Swift
import GoogleMobileAds import UIKit class ViewController : UIViewController , GADFullScreenContentDelegate { var interstitial : GADInterstitialAd ? override func viewDidLoad () { super . viewDidLoad () let request = GADRequest () GADInterstitialAd . load ( withAdUnitID : "ca-app-pub-8123415297019784/4985798738" , request : request , completionHandler : { ( ad , error ) in if let error = error { print ( "Failed to load interstitial ad with error: \(error.localizedDescription)" ) return } self . interstitial = ad self . interstitial . fullScreenContentDelegate = self } ) } }
Objective-C
@import GoogleMobileAds ; @import UIKit ; @interface ViewController ()@property ( nonatomic , strong ) GADInterstitialAd * interstitial ; @end @implementation ViewController - ( void ) viewDidLoad { [ super viewDidLoad ]; GADRequest * request = [ GADRequest request ]; [ GADInterstitialAd loadWithAdUnitID : @"ca-app-pub-3940256099942544/4411468910" request : request completionHandler : ^ ( GADInterstitialAd * ad , NSError * error ) { if ( error ) { NSLog ( @"Failed to load interstitial ad with error: %@" , [ error localizedDescription ]); return ; } self . interstitial = ad ; self . interstitial . fullScreenContentDelegate = self ; }]; } 
Display ad

func showInterstitial () { ... if interstitial . isReady { interstitial . present ( fromRootViewController : self ) } else { print ( "Ad wasn't ready" ) } }
Objective-C
- ( void ) showInterstitial: { ... if ( self . interstitial . isReady ) { [ self . interstitial presentFromRootViewController : self ]; } else { NSLog ( @"Ad wasn't ready" ); } }
v8
Swift
func showInterstitial () { ... if let ad = interstitial { ad . present ( fromRootViewController : self ) } else { print ( "Ad wasn't ready" ) } }
Objective-C
- ( void ) showInterstitial: { ... if ( self . interstitial ) { [ self . interstitial presentFromRootViewController : self ]; } else { NSLog ( @"Ad wasn't ready" ); } }
Presentation ad events
The code snippets below show you how to handle callbacks for when the ad presents (successfully or unsuccessfully) and when it is dismissed.
v7
Swift
override func viewDidLoad () { super . viewDidLoad () interstitial = GADInterstitial ( adUnitID : "ca-app-pub-3940256099942544/4411468910" ) interstitial . delegate = self ... } /// Tells the delegate that an interstitial will be presented . func interstitialWillPresentScreen ( _ ad : GADInterstitial ) { print ( "Interstitial ad will be presented." ) } /// Tells the delegate the interstitial is to be animated off the screen . func interstitialWillDismissScreen ( _ ad : GADInterstitial ) { print ( "Interstitial ad will be dismissed." ) } /// Tells the delegate the interstitial had been animated off the screen . func interstitialDidDismissScreen ( _ ad : GADInterstitial ) { print ( "Interstitial ad dismissed." ) } /// Tells the delegate that a user click will open another app /// ( such as the App Store ), backgrounding the current app . /// /// This is not a reliable callback for an ad click event and is removed in /// version 8.

Display ad and handle reward
Rewarded ads require you to handle the event when a user earns a reward. With
version 7 of the GADRewardedAd 
API, you implement rewardedAd:userDidEarnReward: 
as part of the GADRewardedAdDelegate 
protocol.
For version 8, you implement the GADUserDidEarnRewardHandler 
in order to
present the ad.
v7
Swift
func showRewardedAd () { ... if rewardedAd . isReady { rewardedAd . present ( fromRootViewController : self delegate : self ) } else { print ( "Ad wasn't ready" ) } } /// Tells the delegate that the user earned a reward . func rewardedAd ( _ rewardedAd : GADRewardedAd , userDidEarnReward : GADAdReward ) { // TODO : Reward the user . }
Objective-C
- ( void ) showRewardedAd: { ... if ( self . rewardedAd . isReady ) { [ self . rewardedAd presentFromRootViewController : self delegate : self ]; } else { NSLog ( @"Ad wasn't ready" ); } } /// Tells the delegate that the user earned a reward. - ( void ) rewardedAd: ( GADRewardedAd * ) rewardedAd userDidEarnReward: ( GADAdReward * ) reward { // TODO: Reward the user. }
v8
Swift
func showRewardedAd () { ... if let ad = rewardedAd { ad . present ( fromRootViewController : self , userDidEarnRewardHandler : { let reward = ad . adReward // TODO : Reward the user . } ) } else { print ( "Ad wasn't ready" ) } }
Objective-C
- ( void ) showRewardedAd: { ... if ( self . rewardedAd ) { [ self . rewardedAd presentFromRootViewController : self userDidEarnRewardHandler : ^ { GADAdReward * reward = self . rewardedAd . adReward ; // TODO: Reward the user. }]; } else { NSLog ( @"Ad wasn't ready" ); } }
Presentation ad events
With the GADRewardedAd 
API you pass a GADRewardedAdDelegate 
to the method
that presents the ad. With the GADRewardedAd 
API, you set a GADFullscreenContentDelegate 
as a property on the ad prior to presenting the
ad.

Legacy GADRewardedBasedVideoAd API removal
The newer  GADRewardedAd 
 
API was first introduced back in March 2019 and has been the preferred rewarded
API for over 18 months. It has had more enhancements compared to the legacy GADRewardedBasedVideoAd 
API, including the ability to load more than one
rewarded ad at a time.
The legacy GADRewardedBasedVideoAd 
API is removed in SDK version 8.0.0.
Smart banner deprecation in favor of adaptive banner
Smart banner ads are deprecated in favor of adaptive banner ads. Adaptive banners provide superior performance and more flexibility in setting ad width. If you prefer to continue using full-width banners, that can still be done using adaptive banner, as shown in the following code snippet:
Swift
class ViewController : UIViewController { override func viewDidAppear ( _ animated : Bool ) { super . viewDidAppear ( animated ) // Note: The safe area is not known until viewWillAppear. let adSize = getFullWidthAdaptiveAdSize () } func getFullWidthAdaptiveAdSize () -> GADAdSize { // Here safe area is taken into account, hence the view frame is used after the // view has been laid out. let frame = { () -> CGRect in if #available ( iOS 11.0 , * ) { return view . frame . inset ( by : view . safeAreaInsets ) } else { return view . frame } }() return GADCurrentOrientationAnchoredAdaptiveBannerAdSizeWithWidth ( frame . size . width ) } }
Objective-C
@implementation ViewController - ( void ) viewDidAppear: ( BOOL ) animated { [ super viewDidAppear : animated ]; // Note: The safe area is not known until viewWillAppear. GADAdSize adSize = [ self getFullWidthAdaptiveAdSize ]; } - ( GADAdSize ) getFullWidthAdaptiveAdSize { CGRect frame = self . view . frame ; // Here safe area is taken into account, hence the view frame is used after // the view has been laid out. if (@ available ( iOS 11.0 , * )) { frame = UIEdgeInsetsInsetRect ( self . view . frame , self . view . safeAreaInsets ); } return GADCurrentOrientationAnchoredAdaptiveBannerAdSizeWithWidth ( frame . size . width ); } @end
Leave application callback removal
The willLeaveApplication 
callback for all ad formats has been
removed in favor of the  applicationDidEnterBackground: 
 
and  sceneDidEnterBackground: 
 
methods. Using OS-level APIs notify you whenever users leave your app, regardless of
whether or not it is due to an ad interaction.
Note that the willLeaveApplication 
callback was never intended to be
an ad click handler, and relying on this callback to report clicks did not
produce an accurate metric. For example, a click on the AdChoices
icon that launched an external browser invoked the callback but did not count a
click.
