Is there a compiler option (or some other way) to see where ARC is inserting retain and releases? This is mostly out of curiosity. I can see them in the disassembly code, but that's hard to wade through sometimes.

Before releasing objects, the CLR automatically calls the Finalize method for objects that define a Sub Finalize procedure. The Finalize method can contain code that needs to execute just before an object is destroyed, such as code for closing files and saving state information.
Automatic Reference Counting (ARC) is a memory management option for Objective-C provided by the Clang compiler. When compiling Objective-C code with ARC enabled, the compiler will effectively retain, release, or autorelease where appropriate to ensure the object's lifetime extends through, at least, its last use.
Sending the autorelease message to an object marks it for autorelease. When the autorelease pool drains at the end of each event loop, it sends release to all the objects it owns. By convention, object-creation class methods return an autoreleased object.
How Deinitialization Works. Swift automatically deallocates your instances when they're no longer needed, to free up resources.
No. If the compiler were to provide this, you'd get absolutely overwhelmed by the number of retains/releases, since most of them are taken out during the optimization stage. But the compiler can't even do that, because ARC isn't a pre-processing stage. It's part of the compilation. So you're not going to be able to get anything besides looking at the assembly.
