SwiftUI iOS Developer: APIs, Data and App Architecture for East Africa

Course outline and learning expectations

This is a tutor-led course. The outline shows what your tutor will cover; teaching materials and examinations are provided directly to enrolled students.

What you will learn

• Design maintainable SwiftUI applications with feature boundaries, protocols, dependency injection and testable presentation logic.
• Build resilient API clients with authentication, pagination, retries, request cancellation and useful error mapping.
• Use Swift concurrency safely for parallel work, task cancellation and responsive interfaces.
• Create local-first data flows with SwiftData caching, background refresh and explicit synchronisation states.
• Implement authentication, secure token storage and permission-aware access to notifications and location.
• Add maps, location, deep links and push-notification flows where they create genuine user value.
• Write unit, integration and UI tests for important product journeys.
• Distribute a release candidate through TestFlight with complete metadata, privacy information and tester guidance.

Modules

1. 1

   Maintainable SwiftUI Architecture

   Turning product requirements into features, screens and domain modelsObservation, presentation models and unidirectional data flowProtocols, dependency injection and replacing services in testsFeature folders, reusable packages and avoiding oversized view modelsArchitecture refactor of an existing SwiftUI project
2. 2

   Production API Engineering

   Typed endpoints, request builders and response validationAuthentication headers, refresh tokens and secure session handlingPagination, search, filters, uploads and download progressRetries, exponential backoff, cancellation and actionable errorsNetwork logging without exposing personal or secret data
3. 3

   Swift Concurrency in Real Apps

   Structured concurrency, task groups and async sequencesMainActor, Sendable, isolation and recognising data racesCancellation-aware search and background workBridging callback APIs into async/awaitResponsive loading flows for slower mobile networks
4. 4

   Local-First Data and Synchronisation

   SwiftData repositories, queries, indexes and migrationsCache policies, freshness, stale data and manual refreshPending changes, sync status and idempotent requestsConflict-resolution strategies and recovery after failed syncDesigning offline flows for field teams and customers
5. 5

   Authentication, Permissions and Device Services

   Sign-in flow design and Keychain-based token storagePermission timing, purpose strings and respectful fallback experiencesMapKit, Core Location and location-aware searchLocal notifications, remote-notification concepts and deep linksCamera or document-picker integration for evidence and records
6. 6

   Testing Product Behaviour

   Unit tests with Swift Testing and dependency-controlled fixturesIntegration tests for network and persistence boundariesXCTest UI tests for sign-in, search and offline journeysNetwork-condition and accessibility test matricesBug reporting, regression tests and release acceptance criteria
7. 7
