In Realm, you can do the same thing with just one line. To fetch a file, in Core Data you need approximately 10 lines of code. Migrate Your Queries to be able to retrieve your data as needed. To be able to modify the properties, the object where these were saved needs to be in a ‘write’ transaction. This ensures consistency of data in different threads. Once the Realm objects are added to a Realm object, they can’t be modified. Realm's save operations are a little different than in Core Data and you need to get familiar with this. This is a minor inconvenience, but the developers are promising that the next version of Realm won’t have this problem. Secondly, the current version of Realm can’t deal with object properties with a nil value. Unlike Core Data whose objects have NSManagedObjectID to identify objects uniquely, Realm leaves this to you as the developer. Also, you can safely remove all NSNumber cruft because Realm supports simple numerical data (NSInteger and CGFloat). Realm manages property keywords internally (you don’t have to specify them), which makes the class header look more minimal. You can easily convert managed object subclasses to Realm. You can choose where you want to store the Realm data file, and it will still be optional at runtime. Realm is automatically configured as soon as you access a Realm object for the first time.

There’s going to be a portion of Core Data setup code somewhere in your app and you need to get rid of it all. They outline a nice trick to throw a compiler error for each line of code using Core Data Locate the part of your code that include Core Data code and refactor them. Realm has outline the process thoroughly, but here is a summary: Note that both Core Data and Realm treat data as objects so what you need to do is refactor the Core Data code to use Realm. Many developers have made the journey in a couple hours. Switching To Realm If you have been working with Core Data and you want to move on to Realm, the process is straightforward.
Older versions don’t support this new straightforward solution for managing local storage and databases. To get started with Realm, all you need is at least iOS 8 or OS X 10.9. Realm is great at this and it allows you to handle a lot of data fast. If you are designing an app with a lot of records and for a large number of users, you need to pay special attention to scalability from the very beginning. Also, the database files are shareable among iOS and Android.

Realm is very easy to install and faster to work with compared to SQLite and Core Data. What’s really great about it is that you can handle all the work with a couple of lines of code. Work on its own persistence engine for speed and performance. It is available in Objective-C and Swift, and it’s designed for iOS and Android. This new solution is a cross-platform mobile database called Realm. Realm was designed to be faster and more efficient than the previous database solutions. Realm: There’s a new(ish) player in town called Realm. Although they are fundamentally different, Core data: With Core Data, you are actually storing contents of an object which is represented by a class in Objective-C. Core Data focuses more on objects than the traditional table database methods. Depending on the type of data and the amount of data you need to manage and store, both SQLite and Core Data have their pros and cons. Stores data in tables with one or more columns that contain a specific type of data.Ĭore Data Core Data is the second main iOS storage technology available to app developers. Safe access from multiple processes and threads The reasons for the great popularity of SQLite are its:
SQLite is also very small and light and the complete database can be stored in one cross-platform disk file. It delivers a simple and user-friendly programming interface as it is written in ANSI-C.

SQLite is accessible on Mac OS-X, iOS, Android, Linux, and Windows. It implements a transactional SQL database engine with no configuration and no server required. SQLite SQLite is the most used database engine in the world and its open source as well. This article covers the pros and cons of each option and discusses the process of switching to Realm if you are already using SQLite or Core Data. The most common options for iOS databases are SQLite and Core Data and a relatively newer player called Realm.
#Realm browser app how to
One of the aspects you must figure out is how to store and search for large amounts of data, so you’ll probably use a database. If you want to make a great app that runs fast and just works (no bugs allowed) you’ll have to think about all development aspects of your app carefully.
