iOS and Swift: value models, SwiftUI ownership, and platform evidence
A complete course in Swift optionals and value models, SwiftUI identity, structured concurrency, data boundaries, persistence, accessibility, UIKit integration, and release diagnostics.
Start learningIn this course
Develop an iOS interface by naming who owns each draft, model, task, context, route, and capability. Three levels contain six developed lessons each, with explained examples, diagnostic mistakes, worked exercises, and official Apple or Swift references.
Examples use synthetic workshops, reading lists, drafts, and operation identities. Pure Swift contracts are distinguished from SwiftUI hosting, SwiftData persistence, UIKit integration, device permissions, and signed artifacts. The course does not operate a real service, account, database, device, or distribution workflow.
What you will learn
- Preserve absence, value semantics, model invariants, and stable row identity.
- Choose one source of truth for drafts, bindings, observable models, and navigation.
- Distinguish suspension, cancellation, actor isolation, request freshness, and session scope.
- Validate transport responses, versioned storage, and managed persistence boundaries.
- Design accessible Arabic interfaces and disciplined UIKit adapters.
- Report profiling, signing, and release evidence only for boundaries actually exercised.
Your learning path
Three levels
Swift values and SwiftUI ownership
Optionals, value models, state identity, layout, drafts, and typed navigation.
- Swift values, optionals, and the iOS host
- Value models, collections, and errors
- SwiftUI state, bindings, and identity
- SwiftUI layout and stable lists
- Forms, drafts, and validation
- Navigation values and presentation
Concurrency and data boundaries
Cancellation, HTTP decoding, observed models, freshness, persistence contexts, and test evidence.
- Async, await, and structured cancellation
- URLSession, Codable, and response contracts
- Observation and main-actor models
- Actor reentrancy and result freshness
- Versioned storage and SwiftData contexts
- Swift Testing, XCTest, and test boundaries
Accessible systems and target evidence
Arabic accessibility, performance and ARC, UIKit bridges, permissions, offline reconciliation, and release diagnostics.
- Accessibility, Arabic, and localization
- Instruments, ARC, and performance evidence
- UIKit representables and coordinators
- Permissions, scenes, and private state
- Offline commands and reconciliation
- Release identity, signing, and diagnostics
Who this is for
- Developers with basic programming knowledge who want a principled Swift and SwiftUI foundation.
- Application authors improving concurrency ownership, Arabic accessibility, persistence recovery, and precise target validation.
Before you start
- Functions, collections, object concepts, and basic asynchronous programming vocabulary.
- Executing interface examples requires a separately provisioned compatible Apple development host. The teaching deployment baseline is iOS17 or later; Swift Testing examples require a supporting Swift6-era toolchain such as Xcode16 or later with its actual compatibility checked.
