The Composable Architecture

Composable Architecture (pendeknya TCA) adalah library untuk membangun aplikasi dengan cara yang konsisten dan mudah dimengerti, dengan komposisi, testing, dan design ergonomis. TCA dapat digunakan di SwiftUI, UIKit, dan lainnya, dan di platform Apple apa pun (iOS, macOS, tvOS, dan watchOS)
