# Firebase Carthage ## Context This page introduces and provides instructions for an **experimental** Firebase [Carthage](https://github.com/Carthage/Carthage) distribution. Based on feedback and usage, the Firebase team may decide to [make the Carthage distribution official](https://github.com/firebase/firebase-ios-sdk/issues/1862). Please [let us know](https://github.com/firebase/firebase-ios-sdk/issues) if you have suggestions or questions. ## Carthage Installation [Homebrew](http://brew.sh/) is one way to install Carthage. ```bash $ brew update $ brew install carthage ``` See the [Carthage page](https://github.com/Carthage/Carthage#installing-carthage) for more details and additional installation methods. ## Carthage Usage - Create a Cartfile with a **subset** of the following components - choosing the Firebase components that you want to include in your app. Note that **FirebaseAnalyticsBinary** must always be included. - Starting with the 6.23.0 release, if you're using FirebaseMessaging, FirebasePerformance, FirebaserRemoteConfig, FirebaseABTesting, FirebaseInAppMessaging, or FirebaseML, **FirebaseProtobufBinary** must also be included. ``` binary "https://dl.google.com/dl/firebase/ios/carthage/FirebaseABTestingBinary.json" binary "https://dl.google.com/dl/firebase/ios/carthage/FirebaseAdMobBinary.json" binary "https://dl.google.com/dl/firebase/ios/carthage/FirebaseAnalyticsBinary.json" binary "https://dl.google.com/dl/firebase/ios/carthage/FirebaseAuthBinary.json" binary "https://dl.google.com/dl/firebase/ios/carthage/FirebaseCrashlyticsBinary.json" binary "https://dl.google.com/dl/firebase/ios/carthage/FirebaseDatabaseBinary.json" binary "https://dl.google.com/dl/firebase/ios/carthage/FirebaseDynamicLinksBinary.json" binary "https://dl.google.com/dl/firebase/ios/carthage/FirebaseFirestoreBinary.json" binary "https://dl.google.com/dl/firebase/ios/carthage/FirebaseFunctionsBinary.json" binary "https://dl.google.com/dl/firebase/ios/carthage/FirebaseGoogleSignInBinary.json" binary "https://dl.google.com/dl/firebase/ios/carthage/FirebaseInAppMessagingBinary.json" binary "https://dl.google.com/dl/firebase/ios/carthage/FirebaseMessagingBinary.json" binary "https://dl.google.com/dl/firebase/ios/carthage/FirebaseMLModelInterpreterBinary.json" binary "https://dl.google.com/dl/firebase/ios/carthage/FirebaseMLNLLanguageIDBinary.json" binary "https://dl.google.com/dl/firebase/ios/carthage/FirebaseMLNLSmartReplyBinary.json" binary "https://dl.google.com/dl/firebase/ios/carthage/FirebaseMLNLTranslateBinary.json" binary "https://dl.google.com/dl/firebase/ios/carthage/FirebaseMLNaturalLanguageBinary.json" binary "https://dl.google.com/dl/firebase/ios/carthage/FirebaseMLVisionAutoMLBinary.json" binary "https://dl.google.com/dl/firebase/ios/carthage/FirebaseMLVisionBarcodeModelBinary.json" binary "https://dl.google.com/dl/firebase/ios/carthage/FirebaseMLVisionBinary.json" binary "https://dl.google.com/dl/firebase/ios/carthage/FirebaseMLVisionFaceModelBinary.json" binary "https://dl.google.com/dl/firebase/ios/carthage/FirebaseMLVisionLabelModelBinary.json" binary "https://dl.google.com/dl/firebase/ios/carthage/FirebaseMLVisionObjectDetectionBinary.json" binary "https://dl.google.com/dl/firebase/ios/carthage/FirebaseMLVisionTextModelBinary.json" binary "https://dl.google.com/dl/firebase/ios/carthage/FirebasePerformanceBinary.json" binary "https://dl.google.com/dl/firebase/ios/carthage/FirebaseProtobufBinary.json" binary "https://dl.google.com/dl/firebase/ios/carthage/FirebaseRemoteConfigBinary.json" binary "https://dl.google.com/dl/firebase/ios/carthage/FirebaseStorageBinary.json" ``` - Run `carthage update` - Use Finder to open `Carthage/Build/iOS`. - Copy the contents into the top level of your Xcode project and make sure they're added to the right build target(s). - Add `$(OTHER_LDFLAGS) -ObjC` flag to "Other Linker Flags" in "Build Settings". - Make sure that the build target(s) includes your project's `GoogleService-Info.plist` ([how to download config file](https://support.google.com/firebase/answer/7015592)) - [Delete Firebase.framework from the Link Binary With Libraries Build Phase](https://github.com/firebase/firebase-ios-sdk/issues/911#issuecomment-372455235). - If you're including a Firebase component that has resources, copy its bundles into the Xcode project and make sure they're added to the `Copy Bundle Resources` Build Phase : - For FirebaseMLVisionFaceModel: - ./Carthage/Build/iOS/FaceDetector.framework/GoogleMVFaceDetectorResources.bundle - For FirebaseMLVisionTextModel: - ./Carthage/Build/iOS/TextDetector.framework/GoogleMVTextDetectorResources.bundle - Please note that you shouldn't add any of the Firebase frameworks to the Carthage build phase (`copy-frameworks`). The frameworks contain static libraries that are linked at build time. - Some additional libraries/frameworks may be needed depending on which Firebase frameworks you use, for example: libc++.tbd, sqlite3.tbd, StoreKit.framework, etc. For more information, [go here](https://github.com/firebase/firebase-ios-sdk/issues/9#issuecomment-387947163). - For Crashlytics, do the following steps to automatically upload your app's symbols so your app's crashes are symbolicated: - Download [upload-symbols](https://github.com/firebase/firebase-ios-sdk/raw/master/Crashlytics/upload-symbols) and [run](https://github.com/firebase/firebase-ios-sdk/raw/master/Crashlytics/run). - Put these in the directory where your `.xcodeproj` file lives, eg. `scripts/run` and `scripts/upload-symbols` - Make sure that the files are executable - `chmod +x scripts/run scripts/upload-symbols` - Open your project in Xcode, then select its project file in the left navigator. - From the **Select a project or target** dropdown, select your main build target. - Select the **Build Phases** tab, then click "+" add > **New Run Script Phase**. - Paste the following into your new Run Script, replacing "scripts" with whatever you named your folder: `"${PROJECT_DIR}/scripts/run"` - Add the following dependencies as **Input Files** to the Run Script: - `${DWARF_DSYM_FOLDER_PATH}/${DWARF_DSYM_FILE_NAME}/Contents/Resources/DWARF/${TARGET_NAME}` - `${BUILT_PRODUCTS_DIR}/${INFOPLIST_PATH}` ## Versioning Unlike the CocoaPods distribution, the Carthage distribution is like the Firebase zip release in that all the Firebase components share the same version. Mixing and matching components with different versions may cause linker errors. ## Static Frameworks Note that the Firebase frameworks in the distribution include static libraries. While it is fine to link these into apps, it will generally not work to depend on them from wrapper dynamic frameworks. ## Acknowledgements Thanks to the Firebase community for encouraging this implementation including those who have made this the most updated [firebase-ios-sdk](https://github.com/firebase/firebase-ios-sdk) [issue](https://github.com/firebase/firebase-ios-sdk/issues/9). Thanks also to those who have already done Firebase Carthage implementations, such as https://github.com/soheilbm/Firebase.
