Swiftpack.co - baidu/CarbonGraph as Swift Package

CarbonGraph is a Swift dependency injection / lookup framework for iOS. You can use it to build loose coupling between modules.

The CarbonGraph project contains 2 frameworks:

Features

• ☑ Complete dependency injection capabilities
• ☑ Complete Objective-C support
• ☑ Convenient object definition DSL
• ☑ High-performance thread-safe solution
• ☑ Support resolving native Swift types
• ☑ Support resolving with external parameters
• ☑ Support resolving with circular dependencies
• ☑ Automatic scanning of configuration
• ☑ Additional module life cycle management capabilities

Requirements

• CarbonCore Requirements

• CarbonObjC Version Compatibility

For more information see Compatibility

Installation

CocoaPods is a dependency manager for Cocoa projects. For usage and installation instructions, visit their website. To integrate CarbonGraph into your Xcode project using CocoaPods, specify it in your Podfile:

pod 'CarbonCore', '~> 1.3.3'

Quick Start

• Basic object registration and resolving

let context = ObjectContext()
let definitionBuilder = Definition("filevc")
    .protocol(UIViewController.self)
    .object(FileViewController())
context.register(builder: definitionBuilder)
context[UIViewController.self, name: "filevc"]

let context = ObjectContext()
let definitionBuilder = Definition()
    .object(FileManager() as FileManagerProtocol)
context.register(builder: definitionBuilder)
context[FileManagerProtocol.self]

• Use configuration batch registration

class MyConfiguration: Configuration {
    static func definitions(of context: ObjectContext) -> Definitions {
        Definition()
            .object(FilePath())
        Definition()
            .constructor(FileModel.init(filePath:))
    }
}

let context = ObjectContext()
context.register(configuration: MyConfiguration.self)
context[FileModel.self]

Basic usage

Note: For convenience, the registration of object definitions and the creation of context that appear in the following will be omitted. All definitions in your project must be registered before they can be resolved.

• Use constructor for dependency injection

Definition()
    .protocol(FileViewControllerProtocol.self)
    .constructor(FileViewController.init(fileManager:))
context[FileViewControllerProtocol.self].fileManager

• Use property for dependency injection

Definition()
    .protocol(FileViewControllerProtocol.self)
    .object(FileViewController())
    .property(\.fileManager)
context[FileViewControllerProtocol.self].fileManager

• Use setter for dependency injection

Definition()
    .protocol(FileViewControllerProtocol.self)
    .object(FileViewController())
    .setter(FileViewController.setFileManager(fileManager:))
context[FileViewControllerProtocol.self].fileManager

• Use static factory for manual dependency injection

Definition()
    .factory(fileViewController(context:))
context[FileViewControllerProtocol.self].fileManager

static func fileViewController(context: ObjectContext) -> FileViewControllerProtocol {
    let fileVC = FileViewController()
    fileVC.fileManager = context[FileManagerProtocol]
    return fileVC
}

The same as:

Definition()
    .factory { context in 
        let fileVC = FileViewController()
        fileVC.fileManager = context[FileManagerProtocol]
        return fileVC as FileViewControllerProtocol
    }

• Create objects with external parameters

Definition()
    .factory(fileModel(context:path:name:))
context[FileModelProtocol.self, "/china/beijing", "family.png"]

static func fileModel(context: ObjectContext, path: String, name: String) -> FileModelProtocol {
    FileModel(path: path, name: name)
}
