I can confirm that this is addressed in Xcode 6.1 GM (6A1042b). The code given in the description doesn't work anymore because Swift structs cannot be normally bridged to Obj-C. The code works with a class in place of a struct, and I am able to enumerate the sub-array objects of the NSArray. This issue has been verified as resolved and can be closed.
