[Pippin 10.0.0] 2018-09-05

Changed

• Rewrite NSDate+Components and NSDate+TimeSince in Swift and rename to Date+Components and Date+ElapsedTime, respectively.

Locator

• Make Locators conform to Debuggable, and provide debugging controls for CoreLocationSimulator.
• Instead of setting a property on CoreLocationSimulation with the location data, pass in the raw string from e.g. the environment variable value and parse it internally.
• Add new LocationError enum and change Locator's callback to pass this type. Currently just wraps NSErrors reported by CoreLocation.

Debugging

• DebugFlowController now delegates model deletion back to the consumer app, instead of directly deleting the sqlite database files. Prevents a forced restart of the app to reconstruct the database.
• DatabaseFixsturePickerViewController now requires a parameter of type Environment instead of CoreDataController, which it can get from the environment parameter, as well as logging/alerting/etc.

Model

• Always require a NSManagedObjectContext for fetching, instead of falling back to acquiring a new vended context. Helps with context confinement of model entity instances.
• Instead of requiring an instantiated NSManagedObjectModel in init, just get the bundle identifer of the bundle that contains it, and use the model name it already has to construct the instance internally.

CrudViewController

• No longer sets the Add Item cell's accessibility label to the reuse identifier of the cell. Now just lets the accessibility subsystem automatically infer it.
• Remove reloadTableView() as it is already used in reloadData().

Added

• Add case to LaunchArgument to delete all core data models on launch.
• Add asynchronous Operation subclass, AsyncOperation.
• Add function on CoreDataController to directly vend a context, instead of through a closure parameter via perform(with:).
• Added property on Environment to hold reference to a Locator?.

Fixed

• Hide debugging menu button when the menu is visible.
• Prevent double insertions of the same row in CrudViewController, due to multiple callbacks from the NSFetchedResultsController (in testing, also observed multiple Notifications sent for the same insertion).
