Adds the repository rule xcode_sdk_frameworks #898
Conversation
It scans and configures all SDK frameworks which are required for explicit module builds. Specifically, it 1) uses the bazel_tools//tools/osx:xcode_configure.bzl to fetch all local Xcode infos, 2) finds all frameworks under the xcode SDK path, and 3) uses the swiftc -scan-dependencies mode to fetch the dependency graph among all Swift and Clang SDK modules. We use swift_module_alias to represent a Swift SDK module and sdk_clang_module for a Clang SDK module. Next steps: The dependency among swift_module_alias and sdk_clang_module doesn't work yet. We need to fix that.

is it possible to target at one version only for example? right now me running bazel build --config=explicit_modules --nobuild @xcode_sdk_frameworks//... fails locally with
targets.append(_target_for_module(
File "/Users/yuanfeng/Development/rules_ios/rules/xcode_sdk_frameworks.bzl", line 182, column 13, in _target_for_module
fail("Expect module name by type, but got {}".format(module_name_by_type))
Error in fail: Expect module name by type, but got {"swiftPrebuiltExternal": "_SceneKit_SwiftUI"}
and it seems to happen with xcode 16. Which means we might penalize someone in future just because they installed the new Xcode version.

We can fix it for new xcode versions

i got error here on
ERROR: /private/var/tmp/_bazel_yuanfeng/8f12d9050b931ac3050ca4cf9fc59845/external/_main~xcode_sdk_frameworks~xcode_sdk_frameworks/BUILD.bazel:38:6: configurable attribute "actual" in @@_main~xcode_sdk_frameworks~xcode_sdk_frameworks//:xcode_sdk_frameworks doesn't match this configuration. Would a default condition help?
Conditions checked:
@@_main~xcode_sdk_frameworks~xcode_sdk_frameworks//:xcode_15_4_0_15F31d
To see a condition's definition, run: bazel query --output=build <condition label>.
i tested by adding "//conditions:default": "//version15_4_0_15F31d:xcode_sdk_frameworks", here and the build now succeed. So why you don't hit it and it sounds like we need to ask for a default xcode version or sth?

That's because the repo is pinned to 15.2 while you don't have 15.2 installed. You can update the xcode version in .bazelrc to build --xcode_version=15.4.0.15F31d

how many xcode versions do you have locally? so far i got it green with 15.4 only via:
if not xcode_version_name.startswith("version15_4"):
continue
with 15.1 or 15.2 i got:

and i cannot build with xcode 16 due to the error above....

I didn't test it on 15.1 or 15.2. Thanks for the heads up! We can address the issue with different xcode versions later.
What
It scans and configures all SDK frameworks which are required for explicit module builds.
Specifically, it 1) uses the bazel_tools//tools/osx:xcode_configure.bzl to fetch all local Xcode infos,
2) finds all frameworks under the xcode SDK path,
and 3) uses the swiftc -scan-dependencies mode to fetch the dependency graph among all Swift and Clang SDK modules.
We use swift_module_alias to represent a Swift SDK module and sdk_clang_module for a Clang SDK module.
This PR is based on the previous attempt to support SDK frameworks: #562
Test
Runs
bazel build --config=explicit_modules --nobuild @xcode_sdk_frameworks//...and inspects the generated repository at$(bazel info output_base)/external/_main~xcode_sdk_frameworks~xcode_sdk_frameworks.Next steps:
The dependency among swift_module_alias and sdk_clang_module doesn't work yet. We need to fix that.
