This means our UI will lag every time we save data.Unfortunately, Xcode’s default Core Data project template does this 🙁 As app developers we are always responsible for keeping the UI as responsive as possible.

Needless to say, this is wasteful and might stack up to lag our UI. For example, make it a rule to avoid oversimplifying fetches by using properties and just use functions instead: This makes the function look “slower” from the caller side and users of our API may be more wary of overusing it.When designing models, we usually use an Object-oriented approach when handling attributes shared by several models.For example, if we have a “User” model and a “Message” model both with an “identity” attribute, it’s easy to think to make them share a common super class: One thing to be careful of when using Core Data, however, is that entities with a common super entity will be stored in a single sqlite table.With this method we save memory from redundant data and we gain performance by reducing redundant ‘s notification mechanism we are guaranteed that our View Controller can display the latest and most accurate info.While some teams jump to using other ORMs such as Realm, I believe Core Data is still the most powerful and “complete” ORM for i OS. Diacritic is primarily an adjective, though sometimes used as a noun, whereas diacritical is only ever an adjective.

Some diacritical marks, such as the acute ( ´ ) and grave ( ` ), are often called accents.

Private Queue Concurrency Type) write Context.persistent Store Coordinator = coordinator // ...

// Set our main context as a child of the writer context let main Context = NSManaged Object Context(concurrency Type: .

Main Queue Concurrency Type) main Context.persistent Store Coordinator = coordinator // NOooooo....

directly to the persistent store means that all disk accesses during save will be done on the UI thread.

Diacritical marks may appear above or below a letter, or in some other position such as within the letter or between two letters.
