Summary Using MTLStorageModeManaged builds on iOS in open source when it should not
Mike Wyrzykowski
Reported 2025-02-07 16:31:59 PST
MTLStorageModeManaged is marked `API_UNAVAILABLE(ios)` (see MTLResource.h) but successfully compiles in EWS iOS. However, this leads to the following build breaks (potentially incomplete list): https://bugs.webkit.org/show_bug.cgi?id=271480 https://bugs.webkit.org/show_bug.cgi?id=287301 https://bugs.webkit.org/show_bug.cgi?id=287303 but no where in WebKit can I find MTLStorageModeManaged redefined. Seems like iOS EWS is either using the wrong header files or thinks it is building for macOS?

EWS appears to be building iOS open source builds with the wrong SDK or compiler options. The header file on the bot is correct, but it ignores API_UNAVAILABLE macro: ``` MTLStorageModeManaged API_AVAILABLE(macos(10.11), macCatalyst(13.0)) API_UNAVAILABLE(ios) = 1, ``` from MTLResource.h

I don't see any indication of it building anything wrong in https://s3-us-west-2.amazonaws.com/ews-archives.webkit.org/ios-18-arm64-release-compile-webkit/8cdf2d37-8912.txt, it certainly uses the iOS SDK and deployment target.

Seen again with https://bugs.webkit.org/show_bug.cgi?id=291508, watchOS EWS was green prior to landing but internal watchOS build fails to build
