What is sdwebimage.podspec.json for and how to use it in bazel?

No clue either.
Thread for reference: bazelbuild/bazel#1813 (comment)

I think it was just a comparison between the podspec and the BUILD file for reference of how you may convert them

Correct, this doesn't (to my knowledge) actually exist, it's purely a "I wish the world worked like this."

Ah FWIW this works:

objc_library(
    name = "SDWebImage",
    srcs = glob(
        ["SDWebImage/*.m"],
        exclude = [
            "SDWebImage/UIImage+WebP.m",
            "SDWebImage/SDWebImageWebPCoder.m",
        ],
    ),
    hdrs = glob(
        ["SDWebImage/*.h"],
        exclude = [
            "SDWebImage/UIImage+WebP.h",
            "SDWebImage/SDWebImageWebPCoder.h",
        ],
    ),
    module_name = "SDWebImage",
    sdk_frameworks = [
        "ImageIO",
        "MobileCoreServices",
    ],
    visibility = ["//visibility:public"],
)

Sure, provided you download the SDWebImage source, yeah? I was hoping to jam that into Bazel so it could do some of the package management as well (even though that's not really what it's meant for).

EDIT: I guess if you do the git repo thing you can avoid that?

Yea we use this file with http_archive but git_repository would work just as well

For anyone who stumbles upon this again (hi Mike 👋) here's an updated BUILD file for the latest SDWebImage library

objc_library(
    name = "SDWebImage",
    srcs = glob(
        [
            "SDWebImage/Core/*.m",
            "SDWebImage/Private/*.m",
            "SDWebImage/Private/*.h",
        ],
        exclude = [],
    ),
    hdrs = glob(
        [
            "SDWebImage/Core/*.h",
        ],
        exclude = [],
    ),
    module_name = "SDWebImage",
    sdk_frameworks = [
        "ImageIO",
    ],
    includes = [
        "SDWebImage/Core",
        "SDWebImage/Private",
    ],
    visibility = ["//visibility:public"],
)
