Bug 206463 – Fix SDK availability macros

• Component: WebKit Misc.
• Status: RESOLVED FIXED

[Keith Rollin]

Bug 202243 (fixed in r252174) updated our availability macros for macOS 10.15 and iOS 13. However, some of the changes were not correct at this time and prevent the processing of the macros when building the macOS 10.15 (and, presumably, iOS 13) SDKs. Revert the relevant changes.

No. This was OK. I think. I'll check.

.../System/Library/Frameworks/WebKit.framework/Headers/WKURLSchemeHandler.h has the expected contents.

Broke Catalina builds.

From an internal chat regarding this issue:

OK, I think I have it worked out. The problem is with a file we export called WKFoundation.h This file gets exported and then post-processed. The change I made concerns how its post-processed. The file *was* getting post-processed incorrectly; my change was to fix that and get it to be processed correctly. The problem with an incremental build is that this file continues to exist at its exported location and in its (incorrectly) post-processed state. Because it has a timestamp newer than the original pre-exported, pre-processed versions, the file will not get cleaned up according to the new post-processing rules. This state of things then leads a subsequent header-file-post-processor to come along and mangle the file even more, leading to the build error.

I can fix this by touching WKFoundation.h when I re-upload my patch. This will get a new, clean copy to get exported, and then post-processed correctly.
