• Models. Models. For instance, GenericStates and GenericStateModels.

• Services and Managers. Services, managers, and controllers. For instance, MultiPartFormDataBuilder.

• Helpers. Helper objects and methods. For instance, architectural pattern helpers.

• Extensions. Extensions.

• Global Functions. Global functions. For instance, FIXME(_:) and TODO(_:).

• Macros. Macros. For instance, CodingKeysGeneration.

• API. Objects used for interfacing from you app/package with VCore. For instance, VCoreLocalizationManager.

Package incudes folder Extra, which contains:

• XCode Templates. Templates that can be used for accelerating workflow.

Project includes folder Documentation, which contains:

Showcase

Presentation Host

Manager that injects a presentation host in view hierarchy for modal presentation.

For additional info, refer to "Presentation Host" documentation.

Multipart/Form-Data Builder

MultipartFormDataBuilder with a Dictionary-based file API:

let json: [String: Any?] = [
    "key": "value"
]

let files: [String: (some AnyMultipartFormDataFile)?] = [
    "profile": MultipartFormDataFile(
        mimeType: "image/jpeg",
        data: profileImage?.jpegData(compressionQuality: 0.25)
    ),

    "gallery": galleryImages?.enumerated().compactMap { (index, image) in
        MultipartFormDataFile(
            filename: "IMG_\(index).jpg",
            mimeType: "image/jpeg",
            data: image?.jpegData(compressionQuality: 0.25)
        )
    }
]

let (boundary, httpData): (String, Data) = try MultipartFormDataBuilder().build(
    json: json,
    files: files
)

let url: URL = #url("https://somewebsite.com/api/some_endpoint")

var request: URLRequest = .init(url: url)
request.httpMethod = "POST"
try request.addHTTPHeaderFields(
    object: MultipartFormDataAuthorizedRequestHeaderFields(
        boundary: boundary,
        token: "token"
    )
)
request.httpBody = httpData.nonEmpty

let (data, response): (Data, URLResponse) = try await URLSession.shared.data(for: request)

...

Keychain Service

KeychainService that supports custom queries, and has a dedicated property wrapper:

KeychainService.default.getData(key: "SomeKey")
KeychainService.default.setData(key: "SomeKey", value: data)
KeychainService.default.deleteData(key: "SomeKey")

@KeychainStorage("AccessToken") var accessToken: String?

Various Services and Managers

DigitalTimeFormatter with various configurations:

let formatter: DigitalTimeFormatter = .init()
formatter.string(from: 905048) // "10:11:24:08"

Various SwiftUI Views

AlignedGridLayout that justifies collection of views with an alignment:

private let strings: [String] = [
    "Monday", "Tuesday", "Wednesday",
    "Thursday", "Friday", "Saturday",
    "Sunday"
]

var body: some View {
    AlignedGridLayout(alignment: .center, spacing: 5).callAsFunction({
        ForEach(strings, id: \.self, content: { string in
            Text(string)
                .background(content: { Color.accentColor.opacity(0.5) })
        })
    })
    .padding()
}

Various Declarations

KeyPathInitializableEnumeration that allows for initialization of an enum with a KeyPath:

enum SomeEnum: KeyPathInitializableEnumeration {
    case first
    case second

    var someProperty: Int {
        switch self {
        case .first: 1
        case .second: 2
        }
    }
}

let value: SomeEnum? = .init(key: \.someProperty, value: 2)

Various Extensions

Retrieving CGSize form View:

@State private var size: CGSize = .zero

var body: some View {
    VStack(content: {
        Color.accentColor
            .getSize({ size = $0 })
    })
}

Various Global Functions

Function that calls fatalError because feature is not implemented:

func didTapContinueButton() {
    FIXME()
}

Various Macros

Macro that adds CodingKeys to a declaration:

@CodingKeysGeneration
struct GetPostEntity: Decodable {
    @CKGProperty("id") let id: Int
    @CKGProperty("userId") let userID: Int
    @CKGProperty("title") let title: String
    @CKGProperty("body") let body: String
    
    var attributes: [String: Any?] = [:]
}

// Generates
internal enum CodingKeys: String, CodingKey {
    case id = "id"
    case userID = "userId"
    case title = "title"
    case body = "body"
}
