Each restaurant have an unique ID and the food relates to the restaurant by using a restaurant_id column. To populate a Realm database file, we will use a CSV file filled with the data (you can export your data into CSV format using Excel or Pages or Google Sheet), then create a sample iOS app to convert the CSV file into Realm database.įor this post, we will prepare a restaurants.csv file which contain a list of restaurant and a food.csv which contain a list of food served by the restaurants. If you would like to view your Realm database file in a nice GUI, I recommend downloading the official Realm Browser Mac app.

After finish installing, in the Terminal, type and run the command pod repo update to update the available repositories / libraries for cocoapods.

This should install the Cocoapods library. If you get the error message “You don't have write permissions for the /usr/bin directory.”, try use this command instead sudo gem install cocoapods -n /usr/local/bin. Then type it sudo gem install cocoapods and press Enter to install. To install cocoapods, open up Terminal app (Open spotlight, type “Terminal”).

The SwiftCSV library requires Swift 4.2+ so you must use Xcode 10 or above.Ĭocoapods is a handy library that help us install library / dependencies for Xcode project easily. To make things easier in this tutorial, we will be using Cocoapods to install the SwiftCSV library to read and parse CSV files, and RealmSwift Library to use Realm database.

Get your hands on the actual code and project, saving time from having redo everything from scratch, give it a try! Try out the CSV to Realm Xcode Project and the Realm preset database app

Embed the realm database file into the actual iOS app Xcode project and use itĪt the end of this post, we will have an app that reads data from the preset Realm database and show it in table view like this :.

Create a temporary iOS Xcode project to generate.

Prepare CSV of restaurants and food data.

realm database filled with restaurant and food data, and embed it in an actual iOS app. The big picture of the stepsįor this post, we will be using a list of restaurants and the food served by each restaurants as an example of fixed database. As Realm is open source, your current app shipped with Realm database will still work even after Realm company got shut down. The cons of using Realm is that it is a third party library, MongoDB is in progress of acquiring Realm, the worst that can happen is that MongoDB shut down development of Realm immediately after acquisition and there will be no support afterwards, which is very unlikely but still a possibility. Realm is open source and in my opinion easier to use than Core Data, and also supports filtering / querying using NSPredicate.

realm database file on both Android and iOS app and it will work nicely. The pros of using Realm is that it supports both Android / iOS out of the box, you can use the same. In my opinion, dealing with Core Data and SQLite package can be quite intimidating and time consuming especially if you are just started with iOS development. The cons of using Core Data is that it is an Apple-only technology, if you want to share a same database file across Android and iOS app, there will be additional work required, you can use SQLite as the backing database and use CoreData on top of it, and use the SQLite package on Android to read it.

The pros of using Core Data is that it is backed by Apple, means you are guaranteed that it will keep working down the road to iOS 20 and beyond, and there’s no additional size added to your app for using this library. Pros and Cons of using Core Data/ Realm for prepopulated database

Using the preset realm file in the actual app.

Pros and Cons of using Core Data/ Realm for prepopulated database.

I have used the exact same technique to create and embed preset Realm database in my own iOS apps to show train schedule and routes, Komuter and Rapidly.

“Why not Core Data? We should use as less third party dependencies as possible!”, I heard you, AppCoda has written a great post on how to use preset SQLite Database with Core Data here, I recommend their tutorial if you plan to stick on Core Data.

In this post, we will be using embed Realm database for storing preset static data.

The database will only be used for querying or searching, how do we embed a database prepopulated with data into the app when user first install the app? There might be case where your app have a database containing preset static information that won’t be modified, added or deleted by user.
