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
As part of the improved import of Objective-C APIs into Swift, strip
the "NS" prefix from entities defined in the Foundation
framework. Addresses rdar://problem/24050011, which is part of
SE-0005. Naturally, this is hidden behind -enable-omit-needless-words.
In swift 2.0, type parameter name of `Set` is changed from `T` to `Element`.
Therefore, modified the names which appear in code comments and a document.
The preferred way to create a nil pointer is to use the 'nil' literal.
Affected types:
AutoreleasingUnsafeMutablePointer
OpaquePointer
UnsafeMutablePointer
UnsafePointer
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.
Adding a conformance to Foundation doesn't work because NSString can
be used without loading Foundation. debugDescription is one example of
this.
The only value we derive from the _CocoaStringType is its name, which
makes some APIs more readable. Adding a type safe wrapper around it
serves no purpose since we're almost always immediately casting back
and forth from an 'id'. This was previously done with unsafeBitCast,
which should be avoided unless we really need to reinterpret a bit
pattern.
This reflects the fact that the attribute's only for compiler-internal use, and isn't really equivalent to C's asm attribute, since it doesn't change the calling convention to be C-compatible.
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.)
Like decodeTopLevelObjectOfClass(_:forKey:), this API works very nicely
as a generic method in Swift, and this one is actually the one we expect
to be commonly used. One thing to note here is that these methods are
stricter than their ObjC counterparts: they will do a forced checked cast
even when the unarchiver does not use "secure" coding.
This depends on the previous commit; without it, we do not actually
enforce type safety for these methods.
The API notes change is to make the non-generic version of this method
unavailable so that it does not participate in overload resolution.
Without this we prefer the non-generic method unless there's a contextual
type for the result. I've filed rdar://problem/22243198 to track taking
this out once Foundation has updated their headers.
