I want to make sure this platform and version checking is correct. The PLATFORM(IOS_FAMILY) check will be True for tvOS and watchOS, as well as iOS. But that DYLD_IOS_VERSION_13_4 seems to be iOS-only. So should the pre-processor conditional actually be just PLATFORM(IOS)? And what should happen with macCatalyst? PLATFORM(IOS) will return False for macCatalyst, so if we want to support that platform, we'd also need a PLATFORM(MACCATALYST) check (I assume the iOS version number would be appropriate for that platform?).

I don't think calling dyld_get_program_sdk_version() in the WebKit2 WebContent process will do what you want. AFAIK, dyld_get_program_sdk_version() will only do what you want in the wK2 UIProcess or WK1.

Good catch! I'm pursuing this in https://bugs.webkit.org/show_bug.cgi?id=209030.

From my testing:

tvOS: 0xD0400
watchOS: 0xD0200
macOS: 0xA0F04
iOS: 0xD0400

I suggest static const bool or static constexpr for all of these.

But also, not elegant to have two globals since the first is only used to compute the second. So write it like this:

    static const bool result = [] {
#if PLATFORM(MAC)
        if (applicationSDKVersion() < DYLD_MACOSX_VERSION_10_15_4)
            return false;
#endif
#if PLATFORM(IOS)
        if (applicationSDKVersion() < DYLD_IOS_VERSION_13_4)
            return false;
#elif
        return [NSLocale respondsToSelector:@selector(minimizedLanguagesFromLanguages:)];
    }();
