These mirrors are the default mirrors that get used for all objective-C
object, including some that aren't defined in Foundation:
import Dispatch
println(dispatch_get_global_queue(0,0))
This example isn't fixed yet, because we need to pull all the string
bridging goop out of Foundation and into the core standard library.

This allows reflection clients a more detailed perspective on what precision values they are inspecting, and is largely meant to support improvements to the way Xcode represents floating point numbers in the playgrounds UI (rdar://19124310)

Teach IRGen and the runtime about the extra inhabitants
of function pointers, and take advantage of that in
thin and thick function types.
Also add runtime entrypoints for thin function type
metadata.
Swift SVN r24346
Metatypes have no user-visible structure, but can at least summarize as their type names. This gives us reasonable ad-hoc Printable behavior (thought debugPrint is still wrong, since a type name isn't parsable without being .self'ed).
Swift SVN r23745
Use the recursive demangled name generation I implemented in _typeName for metatypes in _stdlib_getDemangledType as well, so that we get fully-qualified generic names and other goodness.
Swift SVN r23743
Fixes a crash when KVO-observed objects were reflect()ed, and the magic mirror tried to peep the artificial subclass's nonexistent nominal type descriptor. rdar://problem/19060227

refcounting and take advantage of it.
Also, set the Swift1 flag in classes we generate.
Also, initialize a global cache of the non-pointer-isa
mask and use that instead of object_getClass, at least
within the runtime.
Also, centralize the runtime on a _swift_getSuperclass
function and make that use a direct access while we
await word from Greg on the desired ABI requirements.

leak. The release was valid only for some code paths.
Added some comments explaining ownership and parameter passing conventions.
Fixes rdar://17855302, restores half of the leak in rdar://17840810 (only for
objects that inherit from NSObject).
Swift SVN r20820
Mechanically add "Type" to the end of any protocol names that don't end
in "Type," "ible," or "able." Also, drop "Type" from the end of any
associated type names, except for those of the *LiteralConvertible
protocols.
There are obvious improvements to make in some of these names, which can
be handled with separate commits.
Fixes <rdar://problem/17165920> Protocols `Integer` etc should get
uglier names.

This patch allows people to define a func quickLookObject() that returns an NSString, and have the playgrounds pick that up for the sidebar
Fixes rdar://16730829 (or at least gets us through WWDC)
Swift SVN r18629
Our runtime doesn't fix up class field offset vectors for resilient ObjC base classes, causing the offsets to be wrong if the actual size of the base class differs from its compile-time claimed size. Use the ObjC runtime's ivar records instead if the class has ObjC heritage. We can't do this all the time because the ObjC ivar records aren't yet trustworthy for generic classes, but we don't fully support the mix of ObjC heritage and genericity very well anyway yet. Fixes <rdar://problem/17027510> in the short term.
Swift SVN r18622
This is our public API for how quicklooks work in the debugger, and the plan is to have this same API work in playgrounds as well
Fixes rdar://17023157

The <opaque> output is clearly useless, and annoying to see scattered around playgrounds
We don't have bandwidth right now to produce detailed useful reflection information, but at least show a basic understanding of data
Fixes part of rdar://17018392

Blocks need their own type metadata with value witnesses appropriate to the block representation. Fixes <rdar://problem/16918740> and <rdar://problem/16981126>.

The old ones were:
- print/println
- printAny
- printf
- Console
The new printing story is just print/println. Every object can be printed.
You can customize the way it is printed by adopting Printable protocol. Full
details in comments inside stdlib/core/OutputStream.swift.
Printing is not completely finished yet. We still have ReplPrintable, which
should be removed, string interpolation still uses String constructors, and
printing objects that don't conform to Printable will result in printing
mangled names.

This is to be used by playgrounds to provide a better sidebar representation of web pages than simply showing the URL text

We still want to send out image data for those, but UI consumers need to be able to differentiate - should they so desire - a true image from a software sprite rendered in pictorial form
Part of the fix for rdar://16806238
Swift SVN r17471
This tag is meant to trade in image data, but be explicit about the fact that this is a "screenshot" of a UI view rather than a plain ol' picture
Fixes the swift library part of rdar://16796532
Swift SVN r17390
However, this broke for Swift subclasses of NSString because the Swift mirror took precedence over the ObjC NSString choice
Notably, it broke for NSContiguousString
This patch fixes that by explicitly making NSString reflectable, so that its subclasses will automagically do the right thing here
Fixes rdar://16758974
Swift SVN r17059
This is meant to represent to UI consumers the notion of a logical truth value
Previously, we were using a String case to represent such values, but that loses potentially useful information to UI layers
This fixes rdar://16719431
Swift SVN r17037
The cost of hacks to swift_conformsToProtocol is starting to outweigh any benefit to being principled here. We'll get a linker error now if multiple modules declare a conformance for the same type to the same protocol, but that's arguably a good thing for 1.0 anyway, since we aren't set up to get that right in other ways.
Swift SVN r16554
the value buffer comes first.
The motivation for doing this is similar to the
motivation for moving it for class existentials:
it eliminates the need for an offset for the most
common accesses, which is particularly important
for the generic value witnesses.
Also try to hard-code that layout in fewer places,
or at least static_assert the places that have to
do so.
Swift SVN r16279
Its layout information in the ObjC runtime is a complete lie, so we crash if we try to use it to introspect the object. Fixes <rdar://problem/16592777>.
Swift SVN r16228
Language features like erasing concrete metatype
values are also left for the future. Still, baby steps.
The singleton ordinary metatype for existential types
is still potentially useful; we allow it to be written
as P.Protocol.
I've been somewhat cavalier in making code accept
AnyMetatypeType instead of a more specific type, and
it's likely that a number of these places can and
should be more restrictive.
When T is an existential type, parse T.Type as an
ExistentialMetatypeType instead of a MetatypeType.
An existential metatype is the formal type
\exists t:P . (t.Type)
whereas the ordinary metatype is the formal type
(\exists t:P . t).Type
which is singleton. Our inability to express that
difference was leading to an ever-increasing cascade
of hacks where information is shadily passed behind
the scenes in order to make various operations with
static members of protocols work correctly.
This patch takes the first step towards fixing that
by splitting out existential metatypes and giving
them a pointer representation. Eventually, we will
need them to be able to carry protocol witness tables
