Apple Rules for Bazel

This repository contains rules for Bazel that can be used to bundle applications for Apple platforms.

These rules handle the linking and bundling of applications and extensions (that is, the formation of an .app with an executable and resources, archived in an .ipa). Compilation is still performed by the existing objc_library rule in Bazel, and by the swift_library rule available from rules_swift.

Quick setup

Add the following to your WORKSPACE file to add the external repositories, replacing the version number in the tag attribute with the version of the rules you wish to depend on:

load("@bazel_tools//tools/build_defs/repo:git.bzl", "git_repository")

# rules_apple, rules_swift and apple_support no longer support releases. If
# you'd like to pin down these dependencies to a specific commit, please add the
# following to the top of your WORKSPACE, using the commit you'd like to pin for
# each of the repositories.
git_repository(
    name = "build_bazel_rules_apple",
    remote = "https://github.com/bazelbuild/rules_apple.git",
    commit = "[SOME_HASH_VALUE]",
)

git_repository(
    name = "build_bazel_rules_swift",
    remote = "https://github.com/bazelbuild/rules_swift.git",
    commit = "[SOME_HASH_VALUE]",
)

git_repository(
    name = "build_bazel_apple_support",
    remote = "https://github.com/bazelbuild/apple_support.git",
    commit = "[SOME_HASH_VALUE]",
)

load(
    "@build_bazel_rules_apple//apple:repositories.bzl",
    "apple_rules_dependencies",
)

apple_rules_dependencies()

load(
    "@build_bazel_rules_swift//swift:repositories.bzl",
    "swift_rules_dependencies",
)

swift_rules_dependencies()

load(
    "@build_bazel_apple_support//lib:repositories.bzl",
    "apple_support_dependencies",
)

apple_support_dependencies()

Examples

Minimal example:

load("@build_bazel_rules_apple//apple:ios.bzl", "ios_application")

objc_library(
    name = "Lib",
    srcs = glob([
        "**/*.h",
        "**/*.m",
    ]),
    resources = [
        ":Main.storyboard",
    ],
)

# Links code from "deps" into an executable, collects and compiles resources
# from "deps" and places them with the executable in an .app bundle, and then
# outputs an .ipa with the bundle in its Payload directory.
ios_application(
    name = "App",
    bundle_id = "com.example.app",
    families = ["iphone", "ipad"],
    infoplists = [":Info.plist"],
    deps = [":Lib"],
)
