Simple, elegant, and smart Core Data programming with Swift
(Swift, iOS 8+)
## Features
- Supports multiple persistent stores per *data stack*, just the way .xcdatamodeld files are supposed to. CoreStore will also manage one *data stack* by default, but you can create and manage as many as you need.
- Ability to plug-in your own logging framework (or any of your favorite 3rd-party logger)
- Gets around a limitation with other Core Data wrappers where the entity name should be the same as the `NSManagedObject` subclass name. CoreStore loads entity-to-class mappings from the .xcdatamodeld file, so you are free to name them independently.
- Observe a list of `NSManagedObject`'s using `ManagedObjectListController`, a clean wrapper for `NSFetchedResultsController`. Another controller, `ManagedObjectController`, lets you observe changes for a single object without using KVO. Both controllers can have multiple observers as well, so there is no extra overhead when sharing the same data source for multiple screens.
- Makes it hard to fall into common concurrency mistakes. All `NSManagedObjectContext` tasks are encapsulated into safer, higher-level abstractions without sacrificing flexibility and customizability.
- Provides convenient API for common use cases.
- Clean API designed around Swifts code elegance and type safety.
#### TL;DR sample codes
Quick-setup:
```swift
CoreStore.addSQLiteStore("MyStore.sqlite")
```
Simple transactions:
```swift
CoreStore.beginAsynchronous { (transaction) -> Void in
let object = transaction.create(MyEntity)
object.entityID = 1
object.name = "test entity"
transaction.commit { (result) -> Void in
switch result {
case .Success(let hasChanges): println("success!")
case .Failure(let error): println(error)
}
}
}
```
Easy fetching:
```swift
let objects = CoreStore.fetchAll(From(MyEntity))
```
```swift
let objects = CoreStore.fetchAll(
From(MyEntity),
Where("entityID", isEqualTo: 1),
OrderBy(.Ascending("entityID"), .Descending("name")),
Tweak { (fetchRequest) -> Void in
fetchRequest.includesPendingChanges = true
}
)
```
Simple queries:
```swift
let count = CoreStore.queryValue(
From(MyEntity),
Select<Int>(.Count("entityID"))
)
```

## <a name="architecture">Architecture</a>
For maximum safety and performance, CoreStore will enforce coding patterns and practices it was designed for. (Don't worry, it's not as scary as it sounds.) But it is advisable to understand the "magic" of CoreStore before you use it in your apps.
If you are already familiar with the inner workings of CoreData, here is a mapping of `CoreStore` abstractions:
| *Core Data* | *CoreStore* |
| --- | --- |
| `NSManagedObjectModel` / `NSPersistentStoreCoordinator`<br />(.xcdatamodeld file) | `DataStack` |
| `NSPersistentStore`<br />("Configuration"s in the .xcdatamodeld file) | `DataStack` configuration<br />(multiple sqlite / in-memory stores per stack) |
| `NSManagedObjectContext` | `BaseDataTransaction` subclasses<br />(`SynchronousDataTransaction`, `AsynchronousDataTransaction`, `DetachedDataTransaction`) |
Popular libraries [RestKit](https://github.com/RestKit/RestKit) and [MagicalRecord](https://github.com/magicalpanda/MagicalRecord) set up their `NSManagedObjectContext`s this way:
<img src="https://cloud.githubusercontent.com/assets/3029684/6734049/40579660-ce99-11e4-9d38-829877386afb.png" alt="nested contexts" height=271 />
This ensures maximum data integrity between contexts without blocking the main queue. But as <a href="http://floriankugler.com/2013/04/29/concurrent-core-data-stack-performance-shootout/">Florian Kugler's investigation</a> found out, merging contexts is still by far faster than saving nested contexts. CoreStore's `DataStack` takes the best of both worlds by treating the main `NSManagedObjectContext` as a read-only context, and only allows changes to be made within *transactions*:
<img src="https://cloud.githubusercontent.com/assets/3029684/6734050/4078b642-ce99-11e4-95ea-c0c1d24fbe80.png" alt="nested contexts and merge hybrid" height=212 />
This allows for a butter-smooth main thread, while still taking advantage of safe nested contexts.
## <a name="setup">Setting up</a>
The simplest way to initialize CoreStore is to add a default store to the default stack:
```swift
CoreStore.defaultStack.addSQLiteStore()
```
This one-liner does the following:
- Triggers the lazy-initialization of `CoreStore.defaultStack` with a default `DataStack`
- Sets up the stack's `NSPersistentStoreCoordinator`, the root saving `NSManagedObjectContext`, and the read-only main `NSManagedObjectContext`
- Adds an automigrating SQLite store in the *"Application Support"* directory with the file name *"[App bundle name].sqlite"*
- Creates and returns the `NSPersistentStore` instance on success, or an `NSError` on failure
For most cases, this configuration is usable as it is. But for more hardcore settings, refer to this extensive example:
```swift
let dataStack = DataStack(modelName: "MyModel") // loads from the "MyModel.xcdatamodeld" file
switch dataStack.addInMemoryStore(configuration: "Config1") { // creates an in-memory store with entities from the "Config1" configuration in the .xcdatamodeld file
case .Success(let persistentStore): // persistentStore is an NSPersistentStore instance
println("Successfully created an in-memory store: \(persistentStore)"
case .Failure(let error): // error is an NSError instance
println("Failed creating an in-memory store with error: \(error.description)"
}
switch dataStack.addSQLiteStore(
fileURL: sqliteFileURL, // set the target file URL for the sqlite file
configuration: "Config2", // use entities from the "Config2" configuration in the .xcdatamodeld file
automigrating: true, // automatically run lightweight migrations or entity policy migrations when needed
resetStoreOnMigrationFailure: true) { // delete and recreate the sqlite file when migration conflicts occur (useful when debugging)
case .Success(let persistentStore): // persistentStore is an NSPersistentStore instance
println("Successfully created an sqlite store: \(persistentStore)"
case .Failure(let error): // error is an NSError instance
println("Failed creating an sqlite store with error: \(error.description)"
}
CoreStore.defaultStack = dataStack // pass the dataStack to CoreStore for easier access later on
```
Note that you dont need to do the `CoreStore.defaultStack = dataStack` line. You can just as well hold a stack like below and call all methods directly from the `DataStack` instance:
```swift
class MyViewController: UIViewController {
let dataStack = DataStack(modelName: "MyModel")
override func viewDidLoad() {
super.viewDidLoad()
self.dataStack.addSQLiteStore()
}
func methodToBeCalledLaterOn() {
let objects = self.dataStack.fetchAll(From(MyEntity))
println(objects)
}
}
```
The difference is when you set the stack as the `CoreStore.defaultStack`, you can call the stack's methods directly from `CoreStore` itself:
```swift
class MyViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
CoreStore.addSQLiteStore()
}
func methodToBeCalledLaterOn() {
let objects = CoreStore.fetchAll(From(MyEntity))
println(objects)
}
}
```
Check out the *CoreStore.swift* and *DataStack.swift files* if you want to explore the inner workings of the data stack.
