Implement SE-0062: Referencing Objective-C key-paths#2640
Merged
Conversation
Implement the Objective-C #keyPath expression, which maps a sequence of @objc property accesses to a key-path suitable for use with Cocoa[Touch]. The implementation handles @objc properties of types that are either @objc or can be bridged to Objective-C, including the collections that work with key-value coding (Array/NSArray, Dictionary/NSDictionary, Set/NSSet). Still to come: code completion support and Fix-Its to migrate string literal keypaths to #keyPath. Implements the bulk of SR-1237 / rdar://problem/25710611.
Implement code completion support for Objective-C #keyPath expressions, using semantic analysis of the partially-typed keypath argument to provide an appropriate set of results (i.e., just properties and types). This implements all of the necessary parts of SE-0062 / SR-1237 / rdar://problem/25710611, although at some point I'd like to follow it up with some warnings to help migrate existing string literals to

There was a problem hiding this comment.
Good catch! I removed a field and didn't update the bit count.
