Should I use Core Data or SQLite?
The most important difference between Core Data and SQLite is that SQLite is a database while Core Data is not. That is the most important difference because there is very little to compare. Core Data can use SQLite as its persistent store, but the framework itself is not a database. Core Data is not a database.
What is data persistence in Core Data?
Persistence. Core Data abstracts the details of mapping your objects to a store, making it easy to save data from Swift and Objective-C without administering a database directly.
Is SQLite a Core Data?
Although Core Data supports SQLite as a store type, the store format—like those of the other native Core Data stores—is private.
Where is Core Data SQLite file?
Yes, there is always a SQLite behind it. You can find it in the documents folder. As with every new build a new documents folder is created on the simulator it’s getting quite cumbersome to search it manually everytime. Create a function in your app and print it out.
Why core data is faster than SQLite?
2 Answers. Core Data is heavily optimized with regards to caching, lazy-loading and memory management. If you use it (with the SQLite store type), especially in conjunction with NSFetchedResultsController, you should get better performance than you could get with SQLite on your own.
Should I use Realm or core data?
Core Data is incredibly fast if you consider what it does under the hood to do its magic. But Realm is faster, much faster. Realm was built with performance in mind and that shows.
When should I use Core Data?
Core Data manages save and undo functionality for you. It has a persistent store, which tracks changes, and can be flushed to the disk automatically at any number of times (app close, etc.). Core Data and related classes provide easy ways to get your entities into UITableViews, like NSFetchedResultsController.
Can you use SQLite as a persistent store for core data?
I already mentioned that Core Data can use a SQLite database as its persistent store, but it also has support for other persistent store types, including a binary store and an in-memory store. Even though Core Data knows how to use a SQLite database as its persistent store, that doesn’t mean you can hand it any SQLite database.
When to preload data and use existing SQLite database?
When the user launches the app for the very first time, it preloads the data from the data file and puts them into the database. At the time when the app is fully launched, it will be able to use the database, which has been pre-filled with data. The data file can be either bundled in the app or hosted on a cloud server.
When to use binary store or SQLite store?
In a deployed application that uses a large data set, you typically use an SQLite store because it offers high performance and does not require that the entire object graph reside in memory. You might use the binary store if you want store writes to be atomic.
What are the persistent store types in core data?
Persistent Store Types and Behaviors. Core Data provides an in-memory persistent store and three disk-based persistent stores, as described in Table 16-1. The binary store ( NSBinaryStoreType) is an atomic store, as is the XML store ( NSXMLStoreType ). You can also create custom store types, atomic and incremental.
