Sal_: because I am so beyond stumped on this one
[10:53am] Sal_: So for the past 2 years we have had RestKit "vendored" into our project
[10:54am] Sal_: last week we added it as a pod via the .10.3 podspec
[10:54am] Sal_: and all the sudden running the Unit Test target results in an assertion failure in NSManagedObject+ActiveRecord.m
[10:55am] blakewatters: what's the assertion
[10:55am] Sal_: so the assertion is
[10:55am] Sal_:  '[RKManagedObjectStore defaultObjectStore] cannot be nil'
[10:55am] Sal_: but here is where it get's weird...
[10:56am] Sal_: i can confirm with vigorous breakpoints and logs that right up until i run a fetch request, the defaultObjecStore is definitely NOT nil
[10:56am] blakewatters: you may have wound up with 2 copies of RK being linked in

Now that the GateGuru team has been developing on the iOS 5 SDK for awhile, I thought I'd pull together some lessons learned.

• Declare your IBOutlet and IBActions within the private category within your implementation file. This makes them visible to interface builder without cluttering up the external interfaces and leaking implementation details.
• Declare your IBOutlet properties as (nonatomic, weak). The weak reference implies a non-owning reference and ARC will nil it as necessary.
• Delegate properties should be (nonatomic, weak) as well.
• The designated initializer for UIView's is initWithFrame: when initialized programmatically. When loaded from a Storyboard or custom Nib, it is initWithCoder:
• The designated initializer for UIViewController's is initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil when initialized programmatically. It is initWithCoder: when loaded from a Storyboard or Nib.
