Ringkasan Fitur Swift Concurrency yang Digunakan

Fitur	Digunakan Di	Tujuan
`actor`	Worker, Interactor	Isolasi state — thread-safe tanpa lock manual
`@MainActor`	ViewController, Presenter, Router	Jamin semua UIKit di main thread
`async/await`	Semua layer	Alur async yang linear dan mudah dibaca
`Task {}`	ViewController	Bridge sync UIKit callback → async method
`Task.cancel()`	ViewController	Batalkan fetch saat view hilang — hemat resource
`Task.checkCancellation()`	Worker	Cek cancellation sebelum operasi berat
`withTaskCancellationHandler`	Worker	Cleanup resource eksternal saat cancel
`async let`	Interactor	Fetch beberapa sumber data secara parallel
`withTaskGroup`	Worker	Bulk operation dengan jumlah task dinamis
`Task.detached`	Interactor	Operasi background yang tidak terikat isolation parent
`AsyncStream`	Worker	Live polling — push values ke consumer secara async
`for await`	Interactor	Konsumsi AsyncStream secara sequential
`withCheckedContinuation`	ViewController	Bridge UIKit delegate → async function
`withCheckedThrowingContinuation`	LocationService	Bridge delegate yang bisa throw → async throws
`Sendable`	Semua models	Izinkan nilai melewati isolation boundary dengan aman
`nonisolated(unsafe)`	Interactor.selectedUser	Trade-off eksplisit untuk DataStore pattern
