Summary:
Structures which are "enum NS_OPTIONS(XYZ, NSInteger)" in Objective-C are translated into Swift as "struct XYZ : RawOptionSet", so they support bitwise operations. NSStringDrawingOptions doesn't.

Steps to Reproduce:
1. Create a " project in Xcode
2. Create a playground with "import UIKit" declaration
3. Type "let xyz : NSStringDrawingOptions = .UsesLineFragmentOrigin | .UsesFontLeading"
4. Enjoy the error

Expected Results:
No error, NSStringDrawingOptions declared as:

struct NSStringDrawingOptions : RawOptionSet

Actual Results:
Compiler error, NSStringDrawingOptions declared as:

enum NSStringDrawingOptions : Int

Version:
iOS 8.0 SDK (12A4265u)

Notes:
This problem occurs only in iOS SDK. NSStringDrawingOptions in Cocoa version of Foundation.framework is declared as expected. Demo.xcodeproj is in the attachment.

Configuration:
Xcode 6.0 (6A215l) +  OS X 10.9.3 (13D65) running on MacPro5,1
