Status: Resolved:
Product:Xcode 8 Product Version:8.0
Classification:Other Bug Reproducible:Always
 
Summary:
The autocompletion for Obj-C categories used in Swift code does not appear to work for certain classes, NSString being one of them. The code will compile correctly but beginning to type a category method on an NSString in Swift will now autocomplete.

Steps to Reproduce:
1. Write a category on NSString in Objective-C
2. Add a Swift class that uses this category in its bridging header
3. Start typing the function name provided in the category.


Expected Results:
Expect to see autocompleted method names appear for the category method in Swift.

Actual Results:
No autocompleted method names appear, but completing them manually will work.

Version:
Xcode 8 Version 8.0 (8A218a) OS X El Capitan 10.11.6 (15G31)

Notes:
Curiously, when I tested the same methods but created a category on NSObject, the autocomplete did appear for those category methods. This appears to affect categories on NSString, and perhaps others.
