Daniel Duan	62e0da9913	[Property wrappers] Modernize self enclosing test (#30103) ... The init parameter name changed to `wrappedValue` as of Swift 5.2.	2020-02-27 16:05:36 -08:00
Doug Gregor	bc2e605b31	[Property wrappers] Improve enclosing-self subscript handling. ... Extend handling of enclosing-self subscripts by differentiating between the original wrapped property (which now goes through `subscript(_enclosingInstance:wrapped:storage:)`) and the projected property (which goes through `subscript(_enclosingInstance:projected:storage:)`). The new middle argument provides a key path to the property that was accessed, allowing one to distinguish the property being updated.	2019-06-29 23:22:01 -07:00
Doug Gregor	8c54db727b	[Property wrappers] Prototype support for enclosing self-based access ... Allow property wrapper types to support a second access pattern for instance properties of classes. When supported, the property wrapper's static subscript(_enclosingInstance:storage:) is provided with the enclosing "self" and a reference-writable key path referring to the backing storage property. Implements rdar://problem/52222560.	2019-06-29 00:08:49 -07:00
