Apple Rules for Bazel
This repository contains rules for Bazel that can be
used to bundle applications for Apple platforms. They replace the bundling
rules defined in Bazel itself (such as ios_application
, ios_extension
, and
apple_watch2_extension
). This repository also contains rules that run XCTest
based unit and UI tests, replacing the Bazel ios_test
rule.
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; to link those dependencies, these bundling rules use Bazel's
apple_binary
rule
under the hood.
Click here for the reference documentation for the rules and other definitions in this repository.
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")
git_repository(
name = "build_bazel_rules_apple",
remote = "https://github.com/bazelbuild/rules_apple.git",
tag = "0.9.0",
)
load(
"@build_bazel_rules_apple//apple:repositories.bzl",
"apple_rules_dependencies",
)
apple_rules_dependencies()
If you're going to use ios_unit_test
or ios_ui_test
, you'll also need to add
the following to your WORKSPACE
, which is an external dependency needed to run
the tests.
load("@bazel_tools//tools/build_defs/repo:http.bzl", "http_file")
http_file(
name = "xctestrunner",
executable = 1,
urls = ["https://github.com/google/xctestrunner/releases/download/0.2.5/ios_test_runner.par"],
)
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"],
)
See the examples directory for sample applications.
Even though the rules in this repository have the same names as their built-in
counterparts, they cannot be intermixed; for example, an ios_application
from
this repository cannot have an extension that is a built-in ios_extension
or
vice versa.
The wiki for this repository contains a migration guide describing in detail the differences between the old and new rules and how to update your build targets.
- Support for compiling texture atlases
- Improved rules for creating resource bundles
