- **🚦Safer concurrency architecture.** CoreStore makes it hard to fall into common concurrency mistakes. The main `NSManagedObjectContext` is strictly read-only, while all updates are done through serial *transactions*. *(See [Saving and processing transactions](#saving-and-processing-transactions))*
|

Starting CoreStore 4.0, we can now create persisted objects without depending on *.xcdatamodeld* Core Data files. The new `CoreStoreObject` subclass replaces `NSManagedObject`, and specially-typed properties declared on these classes will be synthesized as Core Data attributes.
|
||||
```swift
|
||||
class Animal: CoreStoreObject {
|
||||
let species = Value.Required<String>("species", initial: "")
|
||||
@Field.Stored("species")
|
||||
var species: String = ""
|
||||
}
|
||||
|
||||
class Dog: Animal {
|
||||
let nickname = Value.Optional<String>("nickname")
|
||||
let master = Relationship.ToOne<Person>("master")
|
||||
@Field.Stored("nickname")
|
||||
var nickname: String?
|
||||
|
||||
@Field.Relationship("master")
|
||||
var master: Person?
|
||||
}
|
||||
|
||||
class Person: CoreStoreObject {
|
||||
let name = Value.Required<String>("name", initial: "")
|
||||
let pets = Relationship.ToManyUnordered<Dog>("pets", inverse: { $0.master })
|
||||
@Field.Stored("name")
|
||||
var name: String = ""
|
||||
|
||||
@Field.Relationship("pets", inverse: \Dog.$master)
|
||||
var pets: Set<Dog>
|
||||
}
|
||||
```
|
||||
The property names to be saved to Core Data is specified as the `keyPath` argument. This lets us refactor our Swift code without affecting the underlying database. For example:
|
||||
```swift
|
||||
class Person: CoreStoreObject {
|
||||
private let _name = Value.Required<String>("name", initial: "")
|
||||
@Field.Stored("name")
|
||||
private var internalName: String = ""
|
||||
// note property name is independent of the storage key name
|
||||
}
|
||||
```
|
||||
Here we added an underscore to the property name and made it `private`, but the underlying key-path `"name"` was unchanged so our model will not trigger a data migration.
|
||||
|
||||
> ⚠️**Important:** As a rule, CoreStore can only process *stored properties*. Computed, `static`, `weak`, or `lazy` properties will be ignored and will not be added to the store. It is also strictly advised use `let` instead of `var` to declare these properties, as any changes to the property value will break the schema.
|
||||
|
||||
Also note how `Relationship`s are linked statically with the `inverse:` argument. **All relationships are required to have an "inverse" relationship**. Unfortunately, due to Swift compiler limitation we can only declare the `inverse:` on one end of the relationship-pair.
|
||||
Here we used the property name `internalName` and made it `private`, but the underlying key-path `"name"` was unchanged so our model will not trigger a data migration.
|
||||

||||
To tell the `DataStack` about these types, add all `CoreStoreObject`s' entities to a `CoreStoreSchema`:

And that's all CoreStore needs to build the model; **we don't need *.xcdatamodeld* files anymore.**
|
||||
|
||||
These special properties' values can be accessed or mutated using `.value`:
|
||||
In addition, `@Field` properties can be used to create type-safe key-path strings
|
||||
```swift
|
||||
dataStack.perform(
|

asynchronous: { (transaction) in
|
||||
let dog: Dog = transaction.fetchOne(From<Dog>())!

dog.age.value = age + 1
|
||||
},
|
||||
completion: { /* ... */ }
|
||||
)
|
||||
```
|
||||
|
||||
In addition, `Value` and `Relationship` properties can be used to create type-safe key-paths
|
||||
```swift
|
||||
let keyPath: String = Dog.keyPath { $0.nickname }
|
||||
let keyPath = String(keyPath: \Dog.$nickname)
|

```
|
||||
as well as `Where` and `OrderBy` clauses
|
||||
```swift
|
||||
let puppies = try dataStack.fetchAll(
|
||||
From<Dog>()
|
||||
.where(\.age < 1)
|
||||
.orderBy(.ascending(\.age))
|
||||
.where(\.$age < 5)
|
||||
.orderBy(.ascending(\.$age))
|
||||
)
|
||||
```
|
||||
|
||||
All CoreStore APIs that are usable with `NSManagedObject`s are also available for `CoreStoreObject`s. These include `ListMonitor`s, `ImportableObject`s, fetching, etc.
|
||||
|
||||
### New `@Field` Property Wrapper syntax
|
||||
|
||||
> ⚠️**Important:** `@Field` properties are only supported for `CoreStoreObject` subclasses. If you are using `NSManagedObject`s, you need to keep using `@NSManaged` for your attributes.
|
||||
|
||||
Starting CoreStore 7.1.0, `CoreStoreObject` properties may be converted to `@Field` Property Wrappers.
|
||||
|
||||
> ‼️ Please take note of the warnings below before converting or else the model's hash might change.
|
||||
|
||||
**If conversion is too risky, the current `Value.Required`, `Value.Optional`, `Transformable.Required`, `Transformable.Optional`, `Relationship.ToOne`, `Relationship.ToManyOrdered`, and `Relationship.ToManyUnordered` will all be supported for while so you can opt to use them as is for now.**
|
||||
|
||||
> ‼️ This cannot be stressed enough, but please make sure to set your schema's [`VersionLock`](#versionlocks) before converting!
|
||||
|
||||
#### `@Field.Stored`
|
||||
|
||||
The `@Field.Stored` property wrapper is used for persisted value types. This is the replacement for "non-transient" `Value.Required` and `Value.Optional` properties.

|
||||
|
||||
|
||||
#### `@Field.Coded`
|
||||
|
||||
The `@Field.Coded` property wrapper is used for binary-codable values. This is the new counterpart, **not replacement**, for `Transformable.Required` and `Transformable.Optional` properties. `@Field.Coded` also supports other encodings such as JSON and custom binary converters.
|
||||
|
||||
> ‼️ The current `Transformable.Required` and `Transformable.Optional` mechanism have no safe one-to-one conversion to `@Field.Coded`. Please use `@Field.Coded` only for newly added attributes.

||||
<table>
|
||||
<tr><th>Before</th><th>`@Field.Coded`</th></tr>
|
||||
<tr>
|

<td><pre lang=swift>
|

class Vehicle: CoreStoreObject {

</tr>
|
||||
</table>
|
||||
|
||||
Built-in encoders such as `FieldCoders.NSCoding`, `FieldCoders.Json`, and `FieldCoders.Plist` are available, and custom encoding/decoding is also supported:
|
||||
```swift
|
||||
class Person: CoreStoreObject {
|
||||
<br />
|
||||
struct CustomInfo: Codable {
|
||||
// ...
|
||||
}
|

<br />
|

@Field.Coded(
|

"photo",
|
||||
coder: {
|
||||
encode: { $0.toData() },
|
||||
decode: { Photo(fromData: $0) }
|
||||
}
|
||||
)
|
||||
var photo: Photo?
|
||||
}
|
||||
```
|
||||
|
||||
> ‼️**Important:** Any changes in the encoders/decoders are not reflected in the `VersionLock`, so make sure that the encoder and decoder logic is compatible for all versions of your persistent store.
|
||||
|
||||
#### `@Field.Relationship`
|
||||
|
||||
The `@Field.Relationship` property wrapper is used for link relationships with other `CoreStoreObject`s. This is the replacement for `Relationship.ToOne`, `Relationship.ToManyOrdered`, and `Relationship.ToManyUnordered` properties.
|
||||
|
||||
The type of relationship is determined by the `@Field.Relationship` generic type:
|
||||
|
||||
- `Optional<T>` : To-one relationship
|
||||
- `Array<T>` : To-many ordered relationship
|
||||
- `Set<T>` : To-many unordered relationship

> ⚠️ When converting, make sure that all parameters, including the default values, are exactly the same or else the model's hash might change.
|
||||
|
||||
Also note how `Relationship`s are linked statically with the `inverse:` argument. **All relationships are required to have an "inverse" relationship**. Unfortunately, due to Swift compiler limitation we can declare the `inverse:` on only one of the relationship-pair.
|
||||
|
||||
#### `@Field` usage notes
|
||||
|
||||
**Accessor syntax**
|
||||
|
||||
When using key-path utilities, properties using `@Field` property wrappers need to use the `$` syntax:
|
||||
|
||||
- Before: `From<Person>.where(\.title == "Mr.")`
|
||||
- After: `From<Person>.where(\.$title == "Mr.")`
|
||||
|
||||
This applies to property access using `ObjectPublisher`s and `ObjectSnapshot`s.
|
||||
|
||||
- Before: `let name = personSnapshot.name`
|
||||
- After: `let name = personSnapshot.$name`
|
||||
|
||||
|
||||
**Default values vs. Initial values**
|
||||
|
||||
One common mistake when assigning default values to `CoreStoreObject` properties is to assign it a value and expect it to be evaluated whenever an object is created:
|
||||
|
||||
```swift
|
||||
// ❌
|
||||
class Person: CoreStoreObject {
|
||||
|
||||
@Field.Stored("identifier")
|
||||
var identifier: UUID = UUID() // Wrong!
|
||||
|
||||
@Field.Stored("createdDate")
|
||||
var createdDate: Date = Date() // Wrong!
|
||||
}
|
||||
```
|
||||
|
||||
This default value will be evaluated only when the `DataStack` sets up the schema, and all instances will end up having the same values. This syntax for "default values" are usually used only for actual reasonable constant values, or sentinel values such as `""` or `0`.
|
||||
|
||||
For actual "initial values", `@Field.Stored` and `@Field.Coded` now supports dynamic evaluation during object creation via the `dynamicInitialValue:` argument:
|
||||
|
||||
```swift
|
||||
// ✅
|
||||
class Person: CoreStoreObject {
|
||||
|
||||
@Field.Stored("identifier", dynamicInitialValue: { UUID() })
|
||||
var identifier: UUID
|
||||
|
||||
@Field.Stored("createdDate", dynamicInitialValue: { Date() })
|
||||
var createdDate: Date
|
||||
}
|
||||
```
|
||||
When using this feature, a "default value" should not be assigned (i.e. no `=` expression).
|
||||
|
||||
|
||||
### `VersionLock`s
|
||||
|
||||
While it is convenient to be able to declare entities only in code, it is worrying that we might accidentally change the `CoreStoreObject`'s properties and break our users' model version history. For this, the `CoreStoreSchema` allows us to "lock" our properties to a particular configuration. Any changes to that `VersionLock` will raise an assertion failure during the `CoreStoreSchema` initialization, so you can then look for the commit which changed the `VersionLock` hash.

- parameter initial: the initial value for the property when the object is first created.
|

- parameter keyPath: the permanent attribute name for this property.
|

- parameter versionHashModifier: used to mark or denote a property as being a different "version" than another even if all of the values which affect persistence are equal. (Such a difference is important in cases where the properties are unchanged but the format or content of its data are changed.)
|
||||
- parameter previousVersionKeyPath: used to resolve naming conflicts between models. When creating an entity mapping between entities in two managed object models, a source entity property's `keyPath` with a matching destination entity property's `previousVersionKeyPath` indicate that a property mapping should be configured to migrate from the source to the destination. If unset, the identifier will be the property's `keyPath`.
|
||||
- parameter coder: The `FieldCoderType` to be used for encoding and decoding the value
|
||||
- parameter customGetter: use this closure as an "override" for the default property getter. The closure receives a `ObjectProxy<O>`, which acts as a type-safe proxy for the receiver. When accessing the property value from `ObjectProxy<O>`, make sure to use `field.primitiveValue` instead of `field.value`, which would unintentionally execute the same closure again recursively. Do not make assumptions on the thread/queue that the closure is executed on; accessors may be called from `NSError` logs for example.
|
||||
- parameter customSetter: use this closure as an "override" for the default property setter. The closure receives a `ObjectProxy<O>`, which acts as a fast, type-safe KVC interface for `CoreStoreObject`. The reason a `CoreStoreObject` instance is not passed directly is because the Core Data runtime is not aware of `CoreStoreObject` properties' static typing, and so loading those info everytime KVO invokes this accessor method incurs a cumulative performance hit (especially in KVO-heavy operations such as `ListMonitor` observing.) When accessing the property value from `ObjectProxy<O>`, make sure to use `field.primitiveValue` instead of `field.value`, which would unintentionally execute the same closure again recursively.
|
||||
- parameter affectedByKeyPaths: a set of key paths for properties whose values affect the value of the receiver. This is similar to `NSManagedObject.keyPathsForValuesAffectingValue(forKey:)`.

The closure receives a `ObjectProxy<O>`, which acts as a fast, type-safe KVC interface for `CoreStoreObject`. The reason a `CoreStoreObject` instance is not passed directly is because the Core Data runtime is not aware of `CoreStoreObject` properties' static typing, and so loading those info everytime KVO invokes this accessor method incurs a cumulative performance hit (especially in KVO-heavy operations such as `ListMonitor` observing.)

If the number of objects in the relationship do not satisfy `minCount` and `maxCount`, the transaction's commit (or auto-commit) would fail with a validation error.

- parameter deleteRule: defines what happens to relationship when an object is deleted. Valid values are `.nullify`, `.cascade`, and `.delete`. Defaults to `.nullify`.

- parameter previousVersionKeyPath: used to resolve naming conflicts between models. When creating an entity mapping between entities in two managed object models, a source entity property's `keyPath` with a matching destination entity property's `previousVersionKeyPath` indicate that a property mapping should be configured to migrate from the source to the destination.

When accessing the property value from `ObjectProxy<O>`, make sure to use `field.primitiveValue` instead of `field.value`, which would unintentionally execute the same closure again recursively. Do not make assumptions on the thread/queue that the closure is executed on; accessors may be called from `NSError` logs for example.
|
||||
- parameter customSetter: use this closure as an "override" for the default property setter. The closure receives a `ObjectProxy<O>`, which acts as a fast, type-safe KVC interface for `CoreStoreObject`. The reason a `CoreStoreObject` instance is not passed directly is because the Core Data runtime is not aware of `CoreStoreObject` properties' static typing, and so loading those info everytime KVO invokes this accessor method incurs a cumulative performance hit (especially in KVO-heavy operations such as `ListMonitor` observing.) When accessing the property value from `ObjectProxy<O>`, make sure to use `field.primitiveValue` instead of `field.value`, which would unintentionally execute the same closure again recursively.

- parameter initial: the initial value for the property when the object is first created.
|
||||
- parameter keyPath: the permanent attribute name for this property.
|
||||
- parameter versionHashModifier: used to mark or denote a property as being a different "version" than another even if all of the values which affect persistence are equal. (Such a difference is important in cases where the properties are unchanged but the format or content of its data are changed.)
|
||||
- parameter previousVersionKeyPath: used to resolve naming conflicts between models. When creating an entity mapping between entities in two managed object models, a source entity property's `keyPath` with a matching destination entity property's `previousVersionKeyPath` indicate that a property mapping should be configured to migrate from the source to the destination. If unset, the identifier will be the property's `keyPath`.
|
||||
- parameter customGetter: use this closure as an "override" for the default property getter. The closure receives a `ObjectProxy<O>`, which acts as a type-safe proxy for the receiver. When accessing the property value from `ObjectProxy<O>`, make sure to use `field.primitiveValue` instead of `field.value`, which would unintentionally execute the same closure again recursively. Do not make assumptions on the thread/queue that the closure is executed on; accessors may be called from `NSError` logs for example.
|
||||
- parameter customSetter: use this closure as an "override" for the default property setter. The closure receives a `ObjectProxy<O>`, which acts as a fast, type-safe KVC interface for `CoreStoreObject`. The reason a `CoreStoreObject` instance is not passed directly is because the Core Data runtime is not aware of `CoreStoreObject` properties' static typing, and so loading those info everytime KVO invokes this accessor method incurs a cumulative performance hit (especially in KVO-heavy operations such as `ListMonitor` observing.) When accessing the property value from `ObjectProxy<O>`, make sure to use `field.primitiveValue` instead of `field.value`, which would unintentionally execute the same closure again recursively.
|
||||
- parameter affectedByKeyPaths: a set of key paths for properties whose values affect the value of the receiver. This is similar to `NSManagedObject.keyPathsForValuesAffectingValue(forKey:)`.

- parameter keyPath: the permanent attribute name for this property.
|
||||
- parameter customGetter: use this closure as an "override" for the default property getter. The closure receives a `ObjectProxy<O>`, which acts as a type-safe proxy for the receiver. When accessing the property value from `ObjectProxy<O>`, make sure to use `field.primitiveValue` instead of `field.value`, which would unintentionally execute the same closure again recursively. Do not make assumptions on the thread/queue that the closure is executed on; accessors may be called from `NSError` logs for example.
|
||||
- parameter customSetter: use this closure as an "override" for the default property setter. The closure receives a `ObjectProxy<O>`, which acts as a fast, type-safe KVC interface for `CoreStoreObject`. The reason a `CoreStoreObject` instance is not passed directly is because the Core Data runtime is not aware of `CoreStoreObject` properties' static typing, and so loading those info everytime KVO invokes this accessor method incurs a cumulative performance hit (especially in KVO-heavy operations such as `ListMonitor` observing.) When accessing the property value from `ObjectProxy<O>`, make sure to use `field.primitiveValue` instead of `field.value`, which would unintentionally execute the same closure again recursively.
|
||||
- parameter affectedByKeyPaths: a set of key paths for properties whose values affect the value of the receiver. This is similar to `NSManagedObject.keyPathsForValuesAffectingValue(forKey:)`.

/**
|

An `ObjectProxy` is only used when overriding getters and setters for `CoreStoreObject` properties. Custom getters and setters are implemented as a closure that "overrides" the default property getter/setter. The closure receives an `ObjectProxy<O>`, which acts as a fast, type-safe KVC interface for `CoreStoreObject`. The reason a `CoreStoreObject` instance is not passed directly is because the Core Data runtime is not aware of `CoreStoreObject` properties' static typing, and so loading those info every time KVO invokes this accessor method incurs a heavy performance hit (especially in KVO-heavy operations such as `ListMonitor` observing.) When accessing the property value from `ObjectProxy<O>`, make sure to use `ObjectProxy<O>.$property.primitiveValue` instead of `ObjectProxy<O>.$property.value`, which would execute the same accessor again recursively.
