Build configurations for which the pod should be installed.

Use the bleeding edge version of a Pod.

{
  "name": "AFNetworking",
  "git": "https://github.com/gowalla/AFNetworking.git",
  "tag": "0.7.0"
}

pod 'AFNetworking', :git => 'https://github.com/gowalla/AFNetworking.git', :tag => '0.7.0'

Whether this pod should use modular headers.

Name of the pod.

Custom local filesystem path to add the dependency.

Custom podspec path.

Custom source to search for this dependency.

The git tag to fetch. See the git property for more information.

Test specs can be optionally included via the :testspecs option. By default, none of a Pod's test specs are included.

Version of the pod. CocoaPods supports various versioning options.

Interface representing available configuration for Android native build properties.

Interface representing available configuration for iOS native build properties.

Override the default reactNativeArchitectures list of ABIs to build in gradle.properties.

See: Android documentation for more information.

["arm64-v8a", "x86_64"]

Enable building React Native from source. Turning this on will significantly increase the build times.

Override the default buildToolsVersion version number in build.gradle.

Override the default compileSdkVersion version number in build.gradle.

Enable JavaScript Bundle compression. Turning this on will result in a smaller APK size but may have slower app startup times.

See: Faster App Startup

Enable R8 in release builds to obfuscate Java code and reduce app size.

Enable crunchPngs in release builds to optimize PNG files. This property is enabled by default, but "might inflate PNG files that are already compressed", so you may want to disable it if you do your own PNG optimization.

Enable shrinkResources in release builds to remove unused resources from the app. This property should be used in combination with enableMinifyInReleaseBuilds.

Specifies a single Maven repository to be used as an exclusive mirror for all dependency resolution. When set, all other Maven repositories will be ignored and only this repository will be used to fetch dependencies.

See: Using a Maven Mirror

Add extra maven repositories to all gradle projects.

Takes an array of objects or strings. Strings are passed as the url property of the object with no credentials or authentication scheme.

This adds the following code to android/build.gradle:

allprojects {
 repositories {
  maven {
   url "https://foo.com/maven-releases"
 }
}

By using an AndroidMavenRepository object, you can specify credentials and an authentication scheme.

allprojects {
  repositories {
    maven {
      url "https://foo.com/maven-releases"
      credentials {
       username = "bar"
       password = "baz"
      }
      authentication {
       basic(BasicAuthentication)
      }
    }
  }
}

See: Gradle documentation

Append custom Proguard rules to android/app/proguard-rules.pro.

Override the Kotlin version used when building the app.

Specifies the set of other apps that an app intends to interact with. These other apps are specified by package name, by intent signature, or by provider authority.

See: Android documentation

Override the default minSdkVersion version number in build.gradle.

Enable the Network Inspector.

Interface representing available configuration for Android Gradle plugin PackagingOptions.

Override the default targetSdkVersion version number in build.gradle.

Changes the apps theme to a DayNight variant to correctly support dark mode.

See: Android documentation

Instructs the Android Gradle plugin to compress native libraries in the APK using the legacy packaging system.

See: Android documentation

Indicates whether the app intends to use cleartext network traffic.

For Android 8 and below, the default platform-specific value is true. For Android 9 and above, the default platform-specific value is false.

See: Android documentation

Array of patterns for native libraries that should not be stripped of debug symbols.

Array of patterns for native libraries that should be excluded from being packaged in the APK.

Array of patterns for native libraries where all occurrences are concatenated and packaged in the APK.

Array of patterns for native libraries where only the first occurrence is packaged in the APK.

Specifies an intent filter signature. Your app can discover other apps that have matching <intent-filter> elements. These intents have restrictions compared to typical intent filter signatures.

See: Android documentation for more information.

Specifies one or more apps that your app intends to access. These other apps might integrate with your app, or your app might use services that these other apps provide.

Specifies one or more content provider authorities. Your app can discover other apps whose content providers use the specified authorities. There are some restrictions on the options that you can include in this <provider> element, compared to a typical <provider> manifest element. You may only specify the android:authorities attribute.

Specify a URI authority host that is handled

Specify a MIME type that is handled

Specify a URI scheme that is handled

A string naming the action to perform. Usually one of the platform-defined values, such as SEND or VIEW.

See: Android documentation for more information.

Provides an additional way to characterize the activity handling the intent, usually related to the user gesture or location from which it's started.

A description of the data associated with the intent.

Enable C++ compiler cache for iOS builds.

This speeds up compiling C++ code by caching the results of previous compilations.

See: React Native's documentation on local caches and Ccache documentation.

Override the default iOS "Deployment Target" version in the following projects:

• in CocoaPods projects,
• PBXNativeTarget with "com.apple.product-type.application" productType in the app project.

Add extra CocoaPods dependencies for all targets.

This configuration is responsible for adding the new Pod entries to ios/Podfile.

[
  {
    name: "Protobuf",
    version: "~> 3.14.0",
  }
]

pod 'Protobuf', '~> 3.14.0'

List of CocoaPods that should be linked statically instead of as frameworks.

This is only relevant when use_frameworks! is enabled. Some pods— especially React Native prebuilt binaries—can fail due to modular header issues when built as dynamic frameworks. Declaring them here ensures they are linked statically, avoiding those compatibility problems.

This property is consumed by the use_expo_modules function in expo-modules-autolinking.

Enable the Network Inspector.

Enable aggregation of Privacy Manifests (PrivacyInfo.xcprivacy) from CocoaPods resource bundles. If enabled, the manifests will be merged into a single file. If not enabled, developers will need to manually aggregate them.

See: Privacy manifests guide and Apple's documentation on Privacy manifest files.

Enable use_frameworks! in Podfile to use frameworks instead of static libraries for Pods.

Enable building React Native from source. Turning this on will significantly increase the build times.

On iOS, this controls support for precompiled React Native iOS dependencies (ReactNativeDependencies.xcframework). Setting this value to true will enable building React Native from source and disable the use of precompiled xcframeworks. This feature is available from React Native 0.80 and later when using the new architecture. From React Native 0.81, this setting will also control the use of a precompiled React Native Core (React.xcframework).

See: Precompiled React Native for iOS: Faster builds are coming in 0.81 for more information.

The React Native release level to use for the project. This can be used to enable different sets of internal React Native feature flags.

Enable the experimental Hermes V1 engine.

In React Native 0.83, using Hermes V1 requires building React Native from source. You must set buildReactNativeFromSource to true when enabling this option.
