Summary:
It is impossible to retrieve value from NSDictionary, returned by [NSEntityDescription attributesByName], using NSString as a key.

This issue is only reproducible if:
— binary is compiled on OSX 10.9 with Xcode 5,
— binary is executed on OSX 10.9, 
— [NSEntityDescription attributesByName] returns dictionary with more then one object, 
— the key must be must be of “__NSCFString” class. 

This bug is not reproducible if binary was compiled on OSX 10.8, or binary that was compiled on OSX 10.9 is executed on OSX 10.8.

Steps to Reproduce:
First way to reproduce bug:
1. Have a Apple computer running OSX 10.9 with Xcode 5.
2. Build attached project “PFEncodedStringTest 2 attributes” and run it.
3. Monitor the log.

Second way to reproduce it:
1. Have a Apple computer running OSX 10.9 with Xcode 5.
2. Create new project with core data.
3. Create entity with 2 or more attributes.
4. Get attributesByName NSDictionary from that entity’s description (NSEntityDescription).
5. Generate a NSString key that is of “NSCFString” class.
6. Try to retrieve object for that key, from attributesByName NSDictionary.


Expected Results:
NSDictionary should return NSAttributeDescription object for supplied key.

Actual Results:
NSDictionary returns nil.

Version:
Xcode - Version 5.0.1 (5A2053)
OSX - Version 10.9 (13A603)


Notes:


Configuration:
Entity must have 2 attributes or more.
Ask object for value, from NSDictionary retuned by [NSEntityDescription attributesByName], with NSString key that is of “NSCFString” class.
Compile project on OSX 10.9 with Xcode 5.
Execute binary on OSX 10.9.
