Here is an example description\ntext: \n\n```text\n\u003ckey\u003eNSUserTrackingUsageDescription\u003c/key\u003e\n\u003cstring\u003eThis identifier will be used to deliver personalized ads to you.\u003c/string\u003e\n```\n\nThe usage description appears in the App Tracking Transparency dialog box:\n\nTo present the authorization request, call\n[`requestTrackingAuthorizationWithCompletionHandler:`](//developer.apple.com/documentation/apptrackingtransparency/attrackingmanager/3547037-requesttrackingauthorization).\nWe recommend waiting for the completion callback prior to loading ads so that if\nthe user grants the App Tracking Transparency permission, the Interactive Media\nAds SDK can use the IDFA in ad requests. \n\nSwift \n\n```swift\nimport AppTrackingTransparency\nimport AdSupport\n...\nfunc requestIDFA() {\n ATTrackingManager.requestTrackingAuthorization(completionHandler: { status in\n // Tracking authorization completed. Start loading ads here.\n // loadAd()\n })\n}\n```\n\nObjective-C \n\n```objective-c\n#import \u003cAppTrackingTransparency/AppTrackingTransparency.h\u003e\n#import \u003cAdSupport/AdSupport.h\u003e\n...\n- (void)requestIDFA {\n [ATTrackingManager requestTrackingAuthorizationWithCompletionHandler:^(ATTrackingManagerAuthorizationStatus status) {\n // Tracking authorization completed. Start loading ads here.\n // [self loadAd];\n }];\n}\n```\n\nFor more information about the possible status values, see\n[`ATTrackingManager.AuthorizationStatus`](//developer.apple.com/documentation/apptrackingtransparency/attrackingmanager/authorizationstatus).\n| **Key Point:** For a better user experience, we recommend adding an explainer preceding the call to `requestTrackingAuthorizationWithCompletionHandler:` to clarify the permission and data usage to users.\n\nPublisher first-party ID, formerly known as same app key **Note:** Same app key has been renamed to [Publisher first-party\n| ID](//support.google.com/admob/answer/9997589). The same app key API may change to reflect publisher first-party ID in an upcoming SDK release. This change will not impact existing activation of same app key on IMA SDKs 3.14.5+. All applicable SDK versions will process the identifier seamlessly.\n\n**Prerequisites: IMA SDK for iOS 3.14.5 or higher**\n\nThe Interactive Media Ads SDK for iOS introduced Publisher first-party\nID, formerly known as [same app\nkey](//support.google.com/admanager/answer/9997589) to help you deliver more\nrelevant and personalized ads by using data collected from your apps.\n\nPublisher first-party ID is enabled by default, but you can always choose to\ndisable it in your app by setting\n[`IMASettings::SameAppKeyEnabled`](/interactive-media-ads/docs/sdks/ios/client-side/reference/Classes/IMASettings#sameappkeyenabled) to `false`: \n\nSwift \n\n```swift\nlet settings = IMASettings()\n// Disables Publisher first-party ID, formerly known as same app key.\nsettings.SameAppKeyEnabled = false\nadsLoader = IMAAdsLoader(settings: settings)\n```\n\nObjective-C \n\n```objective-c\nIMASettings *settings = [[IMASettings alloc] init];\n// Disables Publisher first-party ID, formerly known as same app key.\nsettings.SameAppKeyEnabled = false;\nIMAAdsLoader *adsLoader = [[IMAAdsLoader alloc] initWithSettings:settings];\n```\n\nDisclose data usage in the App Store\n\nApple requires that developers publishing apps on the App Store disclose\n[certain information](//developer.apple.com/app-store/app-privacy-details/)\nregarding their apps' data use. Apple has\n[announced](//developer.apple.com/news/?id=vlj9jty9) that these disclosures will\nbe required for new apps and app updates starting December 8, 2020.\n\n[Learn more about the data disclosure\nrequirements](/interactive-media-ads/docs/sdks/tvos/client-side/data-disclosure)."]]
