change includes both the necessary protocol updates and the deprecation
warnings
suitable for migration. A future patch will remove the renamings and
make this
a hard error.
semantically unambiguous.
We didn't actually intend to change how programmers normally
constructed these types, but the change to the object literal
syntax accidentally caused these initializers to have very
natural-seeming signatures. These initializers also created
possible ambiguities with the actual initializers. Renaming
them to refer to their function as literal initializers is the
right thing to do.
Unfortunately, this provided to be somewhat annoying, as the
code was written to assume that the argument tuple following
e.g. #colorLiteral could be directly passed to the initializer.
We solve this by hacking on both ends of the constraint system:
during generation we form a conversion constraint to the
original, idealized parameter type, and during application we
rewrite the argument tuple type to use the actual labels.
This nicely limits the additional complexity to just the
parts dealing with object literals.
Note that we can't just implicitly rewrite the tuple expression
because that would break invariants tying the labels to physical
source ranges. We also don't want to just change the literal
syntax again and break compatibility with existing uses.

* Implement the majority of parsing support for SE-0039.
* Parse old object literals names using new syntax and provide FixIt.
For example, parse "#Image(imageLiteral:...)" and provide a FixIt to
change it to "#imageLiteral(resourceName:...)". Now we see something like:
test.swift:4:9: error: '#Image' has been renamed to '#imageLiteral
var y = #Image(imageLiteral: "image.jpg")
^~~~~~ ~~~~~~~~~~~~
#imageLiteral resourceName
Handling the old syntax, and providing a FixIt for that, will be handled in a separate
commit.
Needs tests. Will be provided in later commit once full parsing support is done.
* Add back pieces of syntax map for object literals.
* Add parsing support for old object literal syntax.
... and provide fixits to new syntax.
Full tests to come in later commit.
* Improve parsing of invalid object literals with old syntax.
* Do not include bracket in code completion results.
* Remove defunct code in SyntaxModel.
* Add tests for migration fixits.
* Add literals to code completion overload tests.
@akyrtzi told me this should be fine.
* Clean up response tests not to include full paths.
* Further adjust offsets.
* Mark initializer for _ColorLiteralConvertible in UIKit as @nonobjc.
* Put attribute in the correct place.
This pull request broke the following tests on several build configurations

This reverts commit c223a3bf06, reversing
changes made to 5c2bb09b09.
Changes:
- Reverted commit reverting original SR-88 commit
- Removed mirror children helper collections and related code
- Rewrote some tests to keep them working properly
- Wrote two more tests for the three pointer APIs to ensure no crashes if created using a value > Int64.max
This reverts commit 8917eb0e5a.
Jira: SR-88
Changes:
- Removed stdlib type conformances to _Reflectable
- Conformed stdlib types to CustomReflectable, CustomPlaygroundQuickLookable
- Rewrote dump() function to not use _reflect()
- CGRect, CGPoint, CGSize now conform to CustomDebugStringConvertible
- Rewrote unit tests for compatibility with new API
1. I think replace the NSMutableSet with Set<UIView>(and Set<NSView>)
could make the operations more Swift-like.
These code works fine in my Playground, and I also pass the test. But
I’m not quite sure it’s ok to use Set here rather than NSSet.
2. I also simplify the read-only computed property in “UIKit.swift”
Most of this is in updating the standard library, SDK overlays, and
piles of test cases to use the new names. No surprises here, although
this shows us some potential heuristic tweaks.
There is one substantive compiler change that needs to be factored out
involving synthesizing calls to copyWithZone()/copy(zone:). Aside from
that, there are four failing tests:
Swift :: ClangModules/objc_parse.swift
Swift :: Interpreter/SDK/Foundation_test.swift
Swift :: Interpreter/SDK/archiving_generic_swift_class.swift
Swift :: Interpreter/SDK/objc_currying.swift
due to two independent remaining compiler bugs:
* We're not getting partial ordering between NSCoder's
encode(AnyObject, forKey: String) and NSKeyedArchiver's version of
that method, and
* Dynamic lookup (into AnyObject) doesn't know how to find the new
names. We need the Swift name lookup tables enabled to address this.
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.)
Un-revert the below commits with the following addition:
add declarations for posix_spawn related APIs to SwiftPrivateDarwinExtras.
posix_spawn-related APIs aren't available in the public SDKs, so force past
the availability by creating our own stubs in the internal DarwinExtras
library.

I had to cut the dependency on CrashReporterClient.h and reimplement
some of that code inline in the Swift runtime. This shoud be OK (even
though not very clean), since the layout of CrashReporter sections is
ABI.
