Firebase Realtime Database adalah database yang dihosting di cloud. Data disimpan sebagai JSON dan disinkronkan secara realtime dengan setiap klien yang terhubung. Ketika Anda mem-build aplikasi lintas platform dengan SDK Android, iOS, dan JavaScript kami, semua klien Anda menggunakan satu instance Realtime Database yang sama dan secara otomatis menerima perubahan data terbaru.
Firebase Realtime Database tersedia di semua platform Apple, termasuk iOS, macOS, macOS Catalyst, tvOS, dan watchOS. Firebase Realtime Database tidak tersedia untuk App Clip.
Petunjuk penyiapan di halaman ini merujuk ke iOS dalam contoh tertentu, tetapi bersifat umum dan berfungsi untuk semua target platform Apple.
Tambahkan aplikasi Anda ke project Firebase di Firebase console.
Membuat Database
Buka bagian Realtime Database di
Firebase console.
Anda akan diminta untuk memilih project Firebase yang ada.
Ikuti alur kerja pembuatan database.
Pilih mode awal untuk Firebase Security Rules Anda:
Mode pengujian
Cocok untuk memulai dengan library klien seluler dan web,
tetapi memungkinkan siapa pun untuk membaca dan menimpa data Anda. Setelah melakukan pengujian, pastikan untuk meninjau bagian Memahami Aturan Firebase Realtime Database.
Untuk mulai menggunakan Web, Apple, atau Android SDK, pilih mode pengujian.
Mode terkunci
Menolak semua pembacaan dan penulisan dari klien seluler dan web.
Server aplikasi terautentikasi masih dapat mengakses database Anda.
Pilih lokasi untuk database.
Bergantung pada lokasi database, URL untuk database baru akan memiliki salah satu format berikut:
DATABASE_NAME.firebaseio.com (untuk database di us-central1)
DATABASE_NAME.REGION.firebasedatabase.app (untuk database di semua lokasi lain)
Klik Done.
Saat Anda mengaktifkan Realtime Database, API di
Pengelola Cloud API juga akan aktif.
Menambahkan Firebase Realtime Database ke aplikasi Anda
Gunakan Swift Package Manager untuk menginstal dan mengelola dependensi Firebase.
Di Xcode, dengan project aplikasi Anda dalam keadaan terbuka, buka File > Add Packages.
Saat diminta, tambahkan repositori SDK platform Apple Firebase:
https://github.com/firebase/firebase-ios-sdk.git
Pilih library Realtime Database.
Tambahkan flag -ObjC ke bagian Other Linker Flags pada setelan build target Anda.
Setelah selesai, Xcode akan otomatis mulai me-resolve dan mendownload dependensi Anda di latar belakang.
Konfigurasi Realtime Database Security Rules
Realtime Database menyediakan bahasa aturan deklaratif sehingga Anda dapat menentukan cara data disusun, diindeks, serta kapan dapat membaca dan menulis data tersebut.
Menyiapkan Firebase Realtime Database
Anda harus melakukan inisialisasi Firebase sebelum ada referensi aplikasi Firebase yang dibuat atau digunakan. Jika hal ini telah dilakukan pada fitur Firebase lainnya, Anda dapat melewati langkah ini.
Impor modul FirebaseCore dalam UIApplicationDelegate Anda, serta semua modul Firebase lainnya yang digunakan oleh delegasi aplikasi Anda.
Misalnya, untuk menggunakan Cloud Firestore dan Authentication:
Konfigurasikan instance bersama FirebaseApp di metode application(_:didFinishLaunchingWithOptions:) delegasi aplikasi Anda:
SwiftUI
// Use Firebase library to configure APIsFirebaseApp.configure()
Swift
// Use Firebase library to configure APIsFirebaseApp.configure()
Objective-C
// Use Firebase library to configure APIs[FIRAppconfigure];
Jika menggunakan SwiftUI, Anda harus membuat delegasi aplikasi dan menambahkannya ke struct App melalui UIApplicationDelegateAdaptor atau NSApplicationDelegateAdaptor. Anda juga harus menonaktifkan swizzling delegasi aplikasi. Untuk mengetahui informasi lebih lanjut, baca petunjuk SwiftUI.
SwiftUI
@mainstructYourApp:App{// register app delegate for Firebase setup@UIApplicationDelegateAdaptor(AppDelegate.self)vardelegatevarbody:someScene{WindowGroup{NavigationView{ContentView()}}}}
Buat referensi ke database dan tentukan lokasi yang menjadi tujuan penulisan Anda.
Pantau dasbor Usage and billing di Firebase console untuk mendapatkan gambaran keseluruhan penggunaan project Anda di berbagai layanan Firebase.
Anda juga dapat membuka dasbor UsageRealtime Database untuk mengetahui informasi penggunaan yang lebih mendetail.

Data is stored as JSON\nand synchronized in realtime to every connected client. When you build\ncross-platform apps with our Android, iOS, and JavaScript SDKs, all of your\nclients share one Realtime Database instance and automatically receive updates with\nthe newest data.\n\nFirebase Realtime Database is available on all Apple platforms, including iOS,\nmacOS, macOS Catalyst, tvOS, and watchOS. It is not available for App Clips.\nThe setup instructions in this page reference iOS in specific examples, but are\ngeneric and work for any Apple platform target.\n\nPrerequisites\n\n1. [Install the Firebase SDK](/docs/ios/setup).\n2. Add your app to your Firebase project in the [Firebase console](//console.firebase.google.com/).\n\nCreate a Database\n\n1. Navigate to the **Realtime Database** section of the\n [Firebase console](https://console.firebase.google.com/project/_/database).\n You'll be prompted to select an existing Firebase project.\n Follow the database creation workflow.\n\n2. Select a starting mode for your Firebase Security Rules:\n\n Test mode\n\n : Good for getting started with the mobile and web client libraries,\n but allows anyone to read and overwrite your data. After testing, **make\n sure to review the [Understand Firebase Realtime Database Rules](/docs/database/security)\n section.**\n\n :\n | **Note:** If you create a database in Test mode and make no changes to the default world-readable and world-writeable Rules within a trial period, you will be alerted by email, then your database rules will deny all requests. Note the expiration date during the Firebase console setup flow.\n\n : To get started with the web, Apple, or Android SDK, select testmode.\n\n Locked mode\n\n : Denies all reads and writes from mobile and web clients.\n Your authenticated application servers can still access your database.\n\n3. Choose a location for the database.\n\n Depending on the\n [location of the database](/docs/projects/locations#rtdb-locations), the\n URL for the new database will be in one of the following forms:\n - \u003cvar translate=\"no\"\u003eDATABASE_NAME\u003c/var\u003e`.firebaseio.com` (for\n databases in `us-central1`)\n\n - \u003cvar translate=\"no\"\u003eDATABASE_NAME\u003c/var\u003e`.`\u003cvar translate=\"no\"\u003eREGION\u003c/var\u003e`.firebasedatabase.app`\n (for databases in all other locations)\n\n4. Click **Done**.\n\nWhen you enable Realtime Database, it also enables the API in the\n[Cloud API Manager](https://console.cloud.google.com/projectselector/apis/api/firebasedatabase.googleapis.com/overview).\n\nAdd Firebase Realtime Database to your app\n\nUse Swift Package Manager to install and manage Firebase dependencies.\n| Visit [our installation guide](/docs/ios/installation-methods) to learn about the different ways you can add Firebase SDKs to your Apple project, including importing frameworks directly and using CocoaPods.\n\n1. In Xcode, with your app project open, navigate to **File \\\u003e Add Packages**.\n2. When prompted, add the Firebase Apple platforms SDK repository: \n\n```text\n https://github.com/firebase/firebase-ios-sdk.git\n```\n| **Note:** New projects should use the default (latest) SDK version, but you can choose an older version if needed.\n3. Choose the Realtime Database library.\n4. Add the `-ObjC` flag to the *Other Linker Flags* section of your target's build settings.\n5. When finished, Xcode will automatically begin resolving and downloading your dependencies in the background.\n\nConfigure Realtime Database Security Rules\n\nThe Realtime Database provides a declarative rules language that allows you to\ndefine how your data should be structured, how it should be indexed, and when\nyour data can be read from and written to.\n| **Note:** By default, read and write access to your database is restricted so only authenticated users can read or write data. To get started without setting up [Authentication](/docs/auth), you can [configure your rules for public access](/docs/rules/basics#default_rules_locked_mode). This does make your database open to anyone, even people not using your app, so be sure to restrict your database again when you set up authentication.\n\nSet up Firebase Realtime Database\n\nYou must initialize Firebase before any Firebase app reference is created or\nused. If you have already done this for another Firebase feature, you can skip\nthis step.\n\n1. Import the `FirebaseCore` module in your `UIApplicationDelegate`, as well as any other [Firebase modules](/docs/ios/setup#available-pods) your app delegate uses. For example, to use Cloud Firestore and Authentication: \n\n SwiftUI \n\n ```swift\n import SwiftUI\n import FirebaseCore\n import FirebaseFirestore\n import FirebaseAuth\n // ...\n \n ```\n\n Swift \n\n ```swift\n import FirebaseCore\n import FirebaseFirestore\n import FirebaseAuth\n // ...\n \n ```\n\n Objective-C \n\n ```objective-c\n @import FirebaseCore;\n @import FirebaseFirestore;\n @import FirebaseAuth;\n // ...\n \n ```\n2. Configure a [`FirebaseApp`](/docs/reference/swift/firebasecore/api/reference/Classes/FirebaseApp) shared instance in your app delegate's `application(_:didFinishLaunchingWithOptions:)` method: \n\n SwiftUI \n\n ```swift\n // Use Firebase library to configure APIs\n FirebaseApp.configure()\n ```\n\n Swift \n\n ```swift\n // Use Firebase library to configure APIs\n FirebaseApp.configure()\n ```\n\n Objective-C \n\n ```objective-c\n // Use Firebase library to configure APIs\n [FIRApp configure];\n ```\n3. If you're using SwiftUI, you must create an application delegate and attach it to your `App` struct via `UIApplicationDelegateAdaptor` or `NSApplicationDelegateAdaptor`. You must also disable app delegate swizzling. For more information, see the [SwiftUI instructions](/docs/ios/learn-more#swiftui). \n\n SwiftUI \n\n ```swift\n @main\n struct YourApp: App {\n // register app delegate for Firebase setup\n @UIApplicationDelegateAdaptor(AppDelegate.self) var delegate\n\n var body: some Scene {\n WindowGroup {\n NavigationView {\n ContentView()\n }\n }\n }\n }\n \n ```\n4. Create a reference to your database and specify the location you want to write to. **Important** : To get a reference to a database other than a `us-central1` default database, you must pass the database URL to `database()` (or for Objective-C `databaseWithURL`). For a `us-central1` default database, you can call `database()` (or `database`) without arguments.\n |\n | You can find your Realtime Database URL in the *Realtime Database* section of the\n | [Firebase console](//console.firebase.google.com/). Depending on the\n | [location of the database](/docs/projects/locations#rtdb-locations),\n | the database URL will be in one of the following forms:\n | - `https://`\u003cvar translate=\"no\"\u003eDATABASE_NAME\u003c/var\u003e`.firebaseio.com` (for databases in `us-central1`)\n | - `https://`\u003cvar translate=\"no\"\u003eDATABASE_NAME\u003c/var\u003e`.`\u003cvar translate=\"no\"\u003eREGION\u003c/var\u003e`.firebasedatabase.app` (for databases in all other locations)\n\n Swift \n **Note:** This Firebase product is not available on the App Clip target. \n\n ```swift\n var ref: DatabaseReference!\n\n ref = Database.database().reference()\n ```\n\n Objective-C \n **Note:** This Firebase product is not available on the App Clip target. \n\n ```objective-c\n @property (strong, nonatomic) FIRDatabaseReference *ref;\n\n self.ref = [[FIRDatabase database] reference];\n ```\n\nNext Steps\n\n- Learn how to [structure data](/docs/database/ios/structure-data) for Realtime Database.\n\n- [Scale your data across multiple database\n instances.](/docs/database/usage/sharding)\n\n- [Read and write data.](/docs/database/ios/read-and-write)\n\n- [View your database in the\n Firebase console.](//console.firebase.google.com/project/_/database/data)\n\n- Prepare to launch your app:\n\n - Enable [App Check](/docs/app-check/ios) to help ensure that only your\n apps can access your databases.\n\n - Set up [budget\n alerts](/docs/projects/billing/avoid-surprise-bills#set-up-budget-alert-emails)\n for your project in the Google Cloud console.\n\n - Monitor the [*Usage and billing*\n dashboard](//console.firebase.google.com/project/_/usage)\n in the Firebase console to get an overall picture of your project's\n usage across multiple Firebase services.\n You can also visit the [Realtime Database *Usage*\n dashboard](//console.firebase.google.com/project/_/database/usage) for more\n detailed usage information.\n\n - Review the [Firebase launch checklist](/support/guides/launch-checklist)."]]
