An Awesome RealmSwift CRUD operation model

Just got started with Realm in your Swift project?

This will save you loads of time

The key file here is RealmService.swift , just copy that file into your project, install the RealmSwift cocoapod and you're good to go 👍.

See installation guide here 👉 ( https://realm.io/docs/swift/latest/ )

Otherwise, there is a ViewController.swift file and a Pokemon.swift file that aim to demonstrate a brief demo on how to use the methods in RealmService.swift

In RealmService.swift

Quick note on these functions;

We have a "Create": func create<T: Object>(object: T)

A "Read" func read<T: Object>(object: T.Type) -> Results<T>!

An "Update" func update<T: Object>(object: T, with dictionary: [String: Any?])

And a "Delete" func delete<T: Object>(_ object: T)

Note: All of these functions are using Generics; these will allow you to pass in any type of object you want to be stored inside your Realm.

There are however a few 'gotchas' with using RealmSwift, as it won't currently support ALL Swift types. So we didn't want to just stop here. We've taken things a step further and made another function or two to help out even further; 😄 One type currently not supported by RealmSwift is Array. Instead they use a type known as List.

Say you want to append a list of objects to be stored in your Realm, we have a solution for that:

func appendToList<T: Object>(list: List<T>?, with items: [T])

There is also a function to help you verify the existence of an object you created;

objectExists(withPrimaryKey primaryKey: Int) -> Bool

Along with some Error handling methods;

func observeRealmError(in vc: UIViewController, completion: @escaping (Error?) -> Void)

and

func post(_ error: Error)

Happy Realming! 😆
