uploads separate transport completion from server commitment, using a durable state machine, reconciliation on launch, and idempotent retries.

concurrency checks make code thread-safe, but who owns an operation and how long it lives are architectural decisions — not something to inherit from a view's lifecycle.

Duo is a prompt to design for available space and content relationships instead of specific devices. https://swiftinpractice.com/editions/13-from-prototype-to-client-delivery/ https://swiftinpractice.com/editions/13-from-prototype-to-client-delivery/ Mon, 02 Feb 2026 12:00:00 GMT Architecture A handoff-friendly Swift structure: feature ownership, a small core, isolated networking, modern concurrency, and tests around risk. https://swiftinpractice.com/editions/12-multi-camera-capture-on-ios/ https://swiftinpractice.com/editions/12-multi-camera-capture-on-ios/ Fri, 30 Jan 2026 12:00:00 GMT Media & Camera Hardware-synchronised AVCaptureMultiCamSession, shared Metal resources, capability checks, and thermal-aware degradation.

Jan 2026 12:00:00 GMT Performance The production lessons behind stable 30–60 FPS camera pipelines: memory flow, zero-copy Metal mapping, thermal limits, and interruptions.

Architecture MVVM-C scales when coordinators own navigation and business rules stay in view models or domain use cases — a real-world SwiftUI perspective.

12:00:00 GMT Architecture Find the real blocker before commissioning a redesign: diagnose architecture, performance, and integration constraints first.

architecture: state machines, compiler-enforced namespaces, and polymorphism without inheritance instead of boolean soup.

GMT Media & Camera Where HLS, AVFoundation, and Metal actually belong in a production video pipeline — and why reaching for Metal before profiling usually makes things slower, not faster.

Accessibility in iOS is product quality and a delivery requirement, not a late polish pass — with the EU's June 2025 deadline making it a business risk too. https://swiftinpractice.com/editions/5-swift-comes-to-android/ https://swiftinpractice.com/editions/5-swift-comes-to-android/ Sat, 25 Oct 2025 12:00:00 GMT Platforms & Devices What the first official Swift Android SDK previews make possible today — and what remains experimental for teams sharing code across platforms.

engineers migrated three production apps (~400K lines) to Swift 6 concurrency over 12 weeks without pausing feature delivery.

12:00:00 GMT Concurrency Hard-won lessons from migrating three production apps to Swift 6's strict concurrency model: what @MainActor doesn't protect, and how actor reentrancy hides in code that looks clean. https://swiftinpractice.com/editions/1-bluetooth-low-energy-in-swift/ https://swiftinpractice.com/editions/1-bluetooth-low-energy-in-swift/ Sun, 05 Oct 2025 12:00:00 GMT Platforms & Devices A practical tour of CoreBluetooth: scanning, connecting, advertising, and the platform rules that trip teams up in production.
