In XCode 4.3.2, when I run the ARC conversion refactor tool, all of my property options that were "retain" are NOT being changed into "strong"

Question

In XCode 4.3.2, when I run the ARC conversion refactor tool, all of my property options that were "retain" are NOT being changed into "strong". Is "strong" implied now or is this just a problem with XCode 4.3.2?

Example:

Before

@property (nonatomic, retain) NSString * someString;

After

@property (nonatomic) NSString * someString;

Answer 1

"strong" is the default when using ARC (LLVM 3.1), so the new code is correct.
(before ARC, the default was "assign")
