Firebase xcframework integration with SPM

A small mirror for https://github.com/firebase/firebase-ios-sdk, to add support for using their binary dependencies (xcframeworks) with swift package manager.

This repo contains a Package.swift file, which uses a binaryTarget for all Firebase libraries (xcframework files are hosted in github releases).

Official SPM Support

Firebase currently supports SPM integration, see the official SDK integration instructions. This repo is an alternative for integrating with their pre-built xcframeworks for faster build times. See in depth discussion for official SPM support for xcframeworks here.

Installation

  • Add the package:

    // swift-tools-version:5.3
// The swift-tools-version declares the minimum version of Swift required to build this package.

import PackageDescription

let package = Package(
    name: "MyLibrary",
    platforms: [.iOS(.v11)],
    products: [
        .library(name: "MyLibrary", targets: ["MyLibraryTarget"])
    ],
    dependencies: [
        .package(
            name: "Firebase",
            url: "https://github.com/afresh-technologies/firebase-ios-sdk-xcframeworks.git",
            .exact("8.10.0")
        ),
    ],
    targets: [
        .target(
            name: "MyLibraryTarget",
            dependencies: [
                .product(name: "Google-Mobile-Ads-SDK", package: "Firebase"),
                .product(name: "FirebaseAnalytics", package: "Firebase")
            ]
        )
    ]
)

  • Add -ObjC to Build Settings -> Other Linker Flags

  • Some Firebase frameworks require resource bundles. Drag and drop the ones you need into your target's Copy Bundle Resources Phase:

How it works

The Package.swift and Sources files are automatically generated via a script, which is set to run in a scheduled cron job via Github Actions.

The script performs the following actions:

  • Downloads the latest release from https://github.com/firebase/firebase-ios-sdk
  • Parses the Firebase.zip to generate Package.swift and Sources/
  • Commits changes on a new branch, creates, and merges a PR
  • Publishes a release, with a tag that mirrors the Firebase release. The release includes the assets needed for the swift package

Running the script locally

  • Install github cli: $ brew install gh
  • Generate the swift package: $ cd .scripts && sh package.sh debug skip-release
