iOS & SwiftUI Mobile Engineering Bootcamp Certificate

Checkpoint 1: Build a SwiftUI application shell with reusable views, explicit state ownership, navigation and a feature structure that separates UI, domain and data concerns.
Checkpoint 2: Integrate a real HTTP API with async/await, typed decoding, loading/error states, retries and cancellation; prove graceful behavior for bad or unavailable responses.
Checkpoint 3: Add search and detail flows with deep navigation; persist favorites or offline data in SwiftData and demonstrate schema relationships plus migration-aware thinking.
Checkpoint 4: Move non-UI work off the main actor where appropriate; test concurrency assumptions, cancellation and race-prone paths while keeping UI updates responsive.
Checkpoint 5: Audit VoiceOver labels, Dynamic Type, contrast, focus and interaction semantics; document at least three accessibility defects and their fixes.
Checkpoint 6: Profile with Instruments, identify one expensive SwiftUI update or data-flow bottleneck, improve it measurably and create a release-ready archive/build checklist.

Day 1: Frame a real mobile workflow, target users, success criteria, navigation map, data sources, offline needs and accessibility requirements; create repo and
Day 2: Build the core SwiftUI screens, reusable components and state model; add deterministic preview/sample data and baseline tests where practical.
Day 3: Integrate the remote API using async/await and typed models; handle loading, empty, error, retry, timeout and cancellation states.
Day 4: Add navigation/search plus SwiftData persistence and relationships; verify create/read/update/delete behavior and offline continuity.
Day 5: Add concurrency hardening and accessibility; test VoiceOver/Dynamic Type and document actor boundaries, cancellation and any remaining limitations.
Day 6: Profile performance with Instruments, fix one measurable issue, add diagnostics/logging and run an injected network or persistence failure scenario.
Day 7: Publish repo, architecture/data-flow diagram, accessibility report, profiling evidence, test notes, demo video, release checklist and a short product decision
