Problem: When I run it on the actual devices (Apple Watch and iPhone), handleWatchKitExtensionRequest does not return data to openParentApplication when the main iPhone app is not active/open. Code in InterfaceController.m in the WatchKit Extension: NSDictionary *requst = @{ @"request" : @"getData"

All objects used as keys in NS(Mutable)Dictionaries must support the NSCopying protocol, and those objects are copied when they're used in the dictionary. I frequently want to use heavier weight objects as keys, simply to map one object to another. What I really mean when I do that is effectively: [dictionary setObject:someObject forKey:[NSValue valueWithPointer:keyObject]]; ("When I come back and hand you this same key object instance again, get me that same value out.") ...which is exactly what I end up doing to get around this design sometimes. (Yes, I know about NSMapTable in desktop Cocoa

ALAssetsLibrary has a way. UIImagePickerController has a way. Photos must have a way too. I see that PHAsset has a location property which will do for the GPS dictionary, but I'm looking to access all of the metadata which include faces, orientation, exposure,

A requirement is if I give a function the Display ID, it'll provide the Display Name in return (or vice versa). Display Name looks something like this: "Color LCD", "SAMSUNG" Display ID looks something like this: "69671872", "893830283" NSScreen in Cocoa (Obj-C), or CGGetActiveDisplayList in Quartz (C), allow you to get the Display ID number for a monitor. Neither appear to have a method
