Macro for convenient use of swift-dependencies
import Dependencies
import DependenciesMacro
@PublicInit
@Dependencies
public struct TestClient {
public var request: @Sendable (_ request: Request) -> Void
}
@DependencyValue(TestClient.self)
public extension DependencyValues {}@PublicInit is a Member Macro and provides a public initializer.
This macro can be applied only to public structs.
@Dependencies is an Extension Macro that can conform TestClient to TestDependencyKey. This macro can also be applied only to structs.
@DependencyValue is a Member Macro; by using a Macro for the extension of DependencyValues, you can add a property of the type specified in the argument
In this example, the macro is expanded as follows.
public struct TestClient {
public var request: @Sendable (_ request: Request) -> Void
public init(
request: @Sendable @escaping (_ request: Request) -> Void
) {
self.request = request
}
}
extension TestClient: TestDependencyKey {
public static let testValue = TestClient(
request: unimplemented("\(Self.self).request")
)
}
public extension DependencyValues {
var testClient: TestClient {
get {
self[TestClient.self]
}
set {
self[TestClient.self] = newValue
}
}
}This library can only be installed from swift package manager.
