I already submitted separate CLs for /api and /components, here I'm doing the rest of this folder Format /sdk/objc/api folder There are a lot of changes in /sdk so I'm splitting it Formatting done via: git ls-files | grep -E '^sdk\/objc\/.*\.(h|cc|mm)' | grep -Ev '^sdk\/objc\/(api|components).*' | xargs clang-format -i No-Iwyu: Includes didn't change and it isn't related to formatting Bug: webrtc:42225392 Change-Id: I8bb63f6696b2649ea642b900b9d9827980cc8315 Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/373884 Reviewed-by: Danil Chapovalov <danilchap@webrtc.org> Commit-Queue: Harald Alvestrand <hta@webrtc.org> Reviewed-by: Harald Alvestrand <hta@webrtc.org> Cr-Commit-Position: refs/heads/main@{#43696}
