BazelPods +

One more way to build CocoaPods with Bazel. It generates Bazel's BUILD files for pods using awesome rules_ios.
Core idea, Podspec parser, Starlark compiler are forked from PodToBUILD

🎸 Let's rock

Don't forget to setup rules_ios and rules_apple first.

Add BazelPods to your MODULE.bazel

bazel_dep(name = "bazelpods", version = "<version>")

Add BazelPods to your WORKSPACE

http_archive(
    name = "bazelpods",
    sha256 = "<sha256>",
    url = "https://github.com/sergeykhliustin/BazelPods/releases/download/<version>/release.tar.gz"
)

load("@bazelpods//:repositories.bzl", "bazelpods_dependencies")

bazelpods_dependencies()

Add post_install action to your Podfile and run pod install

post_install do |installer|
  puts "Generating Pods.json"
  development_pods = installer.sandbox.development_pods
  mapped_pods = installer.analysis_result.specifications.reduce({}) { |result, spec|
    result[spec.name] = {
      name: spec.name,
      podspec: "#{spec.defined_in_file.to_s}",
      development_path: development_pods[spec.name]
    }
    result
  }
  File.open('Pods/Pods.json', 'w') { |file|
    file.write(JSON.pretty_generate(mapped_pods))
  }
end

Run BazelPods

bazel run @bazelpods//:bazelpods -- --src $PWD

See full list of command line options below

Now you can add first level dependencies to your app as //Pods/<pod_name>
Note: if you have multiplatform setup (--platform with more than 1 option), use //Pods/<pod_name>:<pod_name>_<platform>
Enjoy :)

Patches

You can specify patches to use in order you want. Also you can use same patch several times.

• bundle_deduplicate checks if final bundle will contain bundles with same name and avoids them.
  For example, GoogleMaps contains GoogleMaps.bundle in resources and vendored GoogleMaps.xcframework also contains same bundle.
• arm64_to_sim patches legacy frameworks and libraries to support arm64 simulator. Read more arm64-to-sim. By default will run only on arm64 host machine. Use arm64_to_sim_forced to override.
• user_options applies options from --user-options. If not specified but --user-options not empty will be applied in the end.
• missing_sdks scans all sources for import, @import and #import to find missing sdk frameworks and adds them to final configuration.

🤔 History and motivation

There are two existing wonderful alternatives to this project: cocoapods-bazel and PodToBUILD.

cocoapods-bazel generates BUILD files based on targets from Pods.xcodeproj.
As a result of this, we will have some aggregated targets needed for Xcode but redundant for Bazel.
These targets cause issues with resources and module name resolving.
For example, currently, it's not working out of the box for a custom Firebase setup.

PodToBUILD's main idea is to generate BUILD files directly from .podspec info and it's great!
Unfortunately, out of the box, it cannot resolve the whole dependency tree with private pods as Cocoapods do.
We can solve it by letting Cocoapods do its work and vendorise pods after. (something like this)
Another problem is "mixed code" (Swift + Objective-C). It's still in development, so you cannot resolve it with reasonable effort.
Meanwhile, rules_ios already supports it.

BazelPods uses best of all worlds.
Let Cocoapods download, resolve and setup everything for us. After that, BazelPods will generate BUILD files from .podspecs with only needed subspecs with rules from rules_ios. Written in Swift, so it will do it really fast.
