Fundamentals

Layout and Drawing are two different things:

• Layout defines only the positions and sizes of all views on screen.
• Drawing specifies how each view is rendered (how it looks).

Core Data Fundamentals - CheatSheet (Simple)

Here, I will save basic coredata information for anyone/me would like a quick refresh for these fundamentals from time to time.

What is Core Data

• Core Data is not a database, but instead it manages an Object Graph.

Multithreading

• NSManagedObject and NSManagedObjectContext in Core Data are not thread-safe.
• Core Data avoids data race issues by operating on NSManagedObject instances and NSManagedObjectContext instances in a serial queue.
  This is why we need to place the operation code within the closures of perform or performAndWait.
