Places SDK for iOS（新版）では、パフォーマンスが向上し、新しい料金モデルが採用されています。そのため、Places SDK for iOS（旧版）を使用しているアプリを更新する価値があります。機能の比較について詳しくは、SDK を選択するをご覧ください。
このガイドでは、Places SDK for iOS（新規）と Places SDK for iOS（以前のバージョン）の主な違いと、必要な変更を処理する方法について説明します。
移行の請求に関するベスト プラクティス
warning_amber
このガイダンスは、API の使用量が第 2 階層の料金に移行するほど多い場合に適用されます。API の新しいバージョンに移行すると、別の SKU の料金も請求されます。移行月の費用増加を避けるため、できるだけ月の初めに本番環境で新しい API に切り替えることをおすすめします。これにより、移行月の月額料金階層を最も費用対効果の高いものにすることができます。料金階層については、料金ページと料金に関するよくある質問をご覧ください。

Places SDK for iOS（新規）を有効にする
Places SDK for iOS は Places API サービスに依存しています。Places SDK for iOS（新版）の機能を使用するには、まず Google Cloud プロジェクトで Places API（新版）を有効にする必要があります。詳細については、Google Cloud プロジェクトをセットアップするをご覧ください。
次に、アプリで使用する API キーに Places API（新規）を追加したことを確認する必要があります。詳しくは、API キーを使用するをご覧ください。

For more details on comparing features, see\n[Choose your SDK](/maps/documentation/places/ios-sdk/choose-sdk).\n\nUse this guide to understand key differences in Places SDK for iOS\n(New) compared to Places SDK for iOS (Legacy), along with how to\nhandle necessary changes.\n\n\nBilling best practices for migration\n------------------------------------\n\nwarning_amber\n\nThis guidance applies if your API usage is high enough to\nmove into second-tier pricing. When migrating to a newer version of an API,\nyou're also being billed for a different SKU. To avoid increased costs during the month of\nyour transition, we recommend switching to the new APIs in production as close to the\nbeginning of the month as possible. This will ensure that you reach the most cost-effective\nmonthly pricing tiers during the migration month. For information about pricing tiers,\nsee the [pricing page](/maps/billing-and-pricing/pricing)\nand the [pricing FAQ](/maps/billing-and-pricing/faq).\n\n\u003cbr /\u003e\n\n#### Error: `kGMSPlacesRateLimitExceeded`\n\n| **Notice:** If your iOS app is experiencing `kGMSPlacesRateLimitExceeded`\n| errors, you may be using a deprecated version of the Places API.\n| Version 2.7.0 of the Places API was deprecated as of January 29,\n| 2019, and was turned off on **July 29, 2019** . A new version of the Places API\n| is now available. We recommend updating to the new version as soon as possible.\n| For details, see the [migration\n| guide](/maps/documentation/places/ios-sdk/client-migration).\n\nEnable Places SDK for iOS (New)\n-------------------------------\n\nPlaces SDK for iOS relies on the\n**Places API** service. To use the features of\nPlaces SDK for iOS (New), you must first enable\n**Places API (New)** in your Google Cloud project. For more\ninformation, see [Set up your Google Cloud\nproject](/maps/documentation/places/ios-sdk/cloud-setup).\n\nYou then must verify that you have added **Places API\n(New)** to the API key used by your app. For more information, see [Use API\nKeys](/maps/documentation/places/ios-sdk/get-api-key).\n\nGeneral changes\n---------------\n\nSome general changes that apply to multiple APIs include:\n\n- Uses a new pricing model. For pricing information for all APIs, see [Pricing\n for the Places SDK for iOS\n (New)](/maps/billing-and-pricing/pricing#places-pricing).\n\n- [Place Details\n (New)](/maps/documentation/places/ios-sdk/place-details), [Nearby Search\n (New)](/maps/documentation/places/ios-sdk/nearby-search), and [Text Search\n (New)](/maps/documentation/places/ios-sdk/text-search) require field masks\n to specify which fields you want returned in the response.\n\n- [`GMSPlacesClient`](/maps/documentation/places/ios-sdk/reference/objc/Classes/GMSPlacesClient)\n contains new methods to call these new APIs.\n\n- New classes have been added to define the request to each of the new APIs.\n\n- The response `GMSPlace` instance contains the new [`reviews`](/maps/documentation/places/ios-sdk/reference/objc/Classes/GMSPlace#reviews)\n property of type\n [`GMSPlaceReview`](/maps/documentation/places/ios-sdk/reference/objc/Classes/GMSPlaceReview).\n When your app displays information obtained from the `GMSPlace` instance,\n such as photos and reviews, the app must also display the required\n attributions.\n\n For more information, see the documentation on\n [attributions](/maps/documentation/places/ios-sdk/policies#other_attribution_requirements).\n\n| **Note:** Because Text Search (New) and Nearby Search (New) were added to Places SDK for iOS and did not replace any existing APIs, there is no migration required to use them.\n\nAPI-specific changes\n--------------------\n\nThis section includes the following migration guides for each API:\n\n- [Migrate to Place Details (New)](/maps/documentation/places/ios-sdk/migrate-details)\n- [Migrate to Place Photo (New)](/maps/documentation/places/ios-sdk/migrate-photo)\n- [Migrate to Autocomplete (New)](/maps/documentation/places/ios-sdk/migrate-autocomplete)"]]
