os/activity.h or os/log.h. Update cmake files again, hardcoding a Darwin
dependency. The script does not notice that Foundation depends on
CoreGraphics, so add that manually.
Also found that MapKit is supported on WATCHOS but we didn't have dependencies
for that.
Favor one line per supported SDK instead of catch-all dependency lines.
Distinguish from SDKs which have no dependencies vs SDKs which are
unsupported on a particular platform by printing `unsupported` to the
console and remove the line in the cmake file because it should
not exist anyway.
This full cleanup was not done before because of circularity detected by the
util, which has since been fixed.
Support directories with spaces.
added the build breaks. There's already a tool to get proper
dependencies, `utils/find-overlay-dependencies.sh`, so this patch
allows that tool to update the `CMakeLists.txt` files in-place.
Also it adds a line to the `CMakeLists.txt` files for each SDK so that the tool works.
For every struct type for which the frameworks provides an NSValue category for boxing and unboxing values of that type, provide an _ObjectiveCBridgeable conformance in the Swift overlay that bridges that struct to NSValue, allowing the structs to be used naturally with id-as-Any APIs and Cocoa container classes. This is mostly a matter of gyb-ing out boilerplate using `NSValue.init(bytes:objCType:)` to construct the instance, `NSValue.objCType` to check its type when casting, and `NSValue.getValue(_:)` to extract the unboxed value, though there are a number of special snowflake cases that need special accommodation:
- To maintain proper layering, CoreGraphics structs need to be bridged in the Foundation overlay.
- AVFoundation provides the NSValue boxing categories for structs owned by CoreMedia, but it does so using its own internal subclasses of NSValue, and these subclasses do not interop properly with the standard `NSValue` subclasses instantiated by Foundation. To do the right thing, we therefore have to let AVFoundation provide the bridging implementation for the CoreMedia types, and we have to use its category methods to do so.
- SceneKit provides NSValue categories to box and unbox SCNVector3, SCNVector4, and SCNMatrix4; however, the methods it provides do so in an unusual way. SCNVector3 and SCNVector4 are packaged into `CGRect`s and then the CGRect is boxed using `valueWithCGRect:`. SCNMatrix4 is copied into a CATransform3D, which is then boxed using `valueWithCATransform3D:` from CoreAnimation. To be consistent with what SceneKit does, use its category methods for these types as well, and when casting, check the type against the type encoding SceneKit uses rather than the type encoding of the expected type.
As a first step to allowing the build script to build *only*
static library versions of the stdlib, change `add_swift_library`
such that callers must pass in `SHARED`, `STATIC`, or `OBJECT_LIBRARY`.
Ideally, only these flags would be used to determine whether to
build shared, static, or object libraries, but that is not currently
the case -- `add_swift_library` also checks whether the library
`IS_STDLIB` before performing certain additional actions. This will be
cleaned up in a future commit.
At some point I want to propose a revised model for exports, but for now
just mark that support for '@exported' is still experimental and subject
to change. (Thanks, Max.)
This came out of today's language review meeting.
The intent is to match #available with the attribute
that describes availability.
This is a divergence from Objective-C.

On OS X 10.10 and earlier, CoreImage is a sub-framework of QuartzCore.
Users of CoreImage use "import QuartzCore" and link against QuartzCore.
On OS X 10.11 (and in the OS X 10.11 SDK), CoreImage is a top-level
framework. Users of CoreImage use "import CoreImage" and would link against
CoreImage. Of course, QuartzCore continues to re-export CoreImage's API.
When backwards-deploying, we need to continue linking against QuartzCore,
but still need to bring in the overlay if you import CoreImage. That's
what this patch does.

Enable checking for uses of potentially unavailable APIs. There is
a frontend option to disable it: -disable-availability-checking.
This commit updates the SDK overlays with @availability() annotations for the
declarations where the overlay refers to potentially unavailable APIs. It also changes
several tests that refer to potentially unavailable APIs to use either #available()
or @availability annotations.

The standard library has grown significantly, and we need a new
directory structure that clearly reflects the role of the APIs, and
allows future growth.
See stdlib/{public,internal,private}/README.txt for more information.
