iOS App Development Training in Pune with Placement

Swift as a language, before any UI appears. Variables and constants, the type system and inference, optionals with `?`, `if let`, `guard let` and nil-coalescing — plus a clear account of why force-unwrapping with `!` is a crash waiting to happen.

Control flow, functions with argument labels, closures and trailing-closure syntax, and the collection types with `map`, `filter`, `reduce` and `compactMap`. Structs, classes and enums are introduced with associated values and the value-versus-reference distinction that shapes every later design decision.

The half of Swift that separates working code from idiomatic code. Protocols and protocol-oriented design, extensions and default implementations, associated types, and opaque return types with `some` and `any` — the distinction interviewers use to gauge real Swift depth.

Generics with constraints and `where` clauses, then error handling: `throws` and `try`, typed throws, `Result`, and defer. Memory management closes the module — ARC, strong, weak and unowned references, and the retain cycles that closures create if capture lists are ignored.

The tooling every iOS job assumes you already know. Xcode 16 navigation, the build system, schemes, targets and configurations; simulator and physical-device runs with a free developer account; and the debugger — breakpoints, LLDB, the view hierarchy inspector and the memory graph.

Swift Package Manager covers dependency management, local packages and modularising an app into feature modules. The module also covers Info.plist and entitlements, asset catalogues, build settings and xcconfig files, and reading the compiler errors that Swift is notorious for phrasing unhelpfully.

SwiftUI is the default toolkit for every new iOS app, and the course treats UIKit as interop rather than a starting point. The `View` protocol, view composition and why small views are the unit of reuse, and the modifier system where order genuinely changes the result.

State is the centre: `@State` for local value state, `@Binding` for two-way handoff, `@Environment` for ambient values, and the single-source-of-truth discipline. Layout covers VStack, HStack, ZStack, Grid, Spacer, alignment guides, and the SwiftUI layout negotiation of proposed size and reported size.

Building multi-screen apps. `NavigationStack` with value-based destinations and `NavigationPath` for programmatic navigation — including the deep-link and restore-state cases that hand-rolled navigation gets wrong. `NavigationSplitView` for iPad and Mac layouts, tab views, sheets, popovers and full-screen covers.

Lists cover `ForEach` with stable identity, sections, swipe actions, pull-to-refresh, searchable and lazy loading for large data. Forms and controls close the module — pickers, toggles, steppers, focus state, validation and keyboard handling.

State beyond a single screen. The Observation framework is the modern default — the `@Observable` macro replacing `ObservableObject` and `@Published`, with automatic dependency tracking that only re-renders views actually reading a changed property. `ObservableObject` is covered as legacy you will inherit.

Architecture then gets an honest treatment: the MV pattern SwiftUI's design implies, MVVM and where its view models genuinely help, and The Composable Architecture as the structured option larger teams adopt. Dependency injection through the environment closes the module.

Asynchronous Swift as it is written in 2026. `async`/`await` replacing completion handlers, structured concurrency with `Task` and `async let`, task groups for parallel work, and cancellation that propagates through the tree rather than being checked ad hoc.

`AsyncSequence` and `AsyncStream` cover streaming values, including bridging a delegate or notification API into a stream. The module also covers `Task` lifetime tied to a SwiftUI view with `.task`, priorities, and bridging legacy completion-handler APIs with continuations — the migration every real codebase needs.

The largest change Swift has made in years, and a reliable interview subject. Actors for data-race-free shared mutable state, actor isolation and the `await` that crossing it requires, and reentrancy — the subtlety that surprises people who treat an actor as a lock.

`@MainActor` for UI isolation, global actors, and `Sendable` conformance with the checking that Swift 6 language mode makes an error rather than a warning. The module works through migrating a real codebase to strict concurrency, including `nonisolated`, `@unchecked Sendable` and when each is legitimate.

Talking to a backend the Apple-native way. `URLSession` with `async`/`await`, request construction, headers and query items, and the response and status-code handling that separates a real client from a demo.

`Codable` covers decoding and encoding, coding keys, nested and heterogeneous JSON, date strategies and custom decoding for the APIs that do not match your model. Errors are modelled as a typed enum spanning transport, HTTP and decoding failures. Authentication, token refresh, retry, caching, background downloads and mocking with `URLProtocol` close the module.

Data that survives relaunch. SwiftData as the modern default — `@Model`, the model container and context, `@Query` in SwiftUI, relationships, delete rules, predicates, sorting and schema migration. Core Data is covered as legacy, because a large share of Pune iOS work involves inheriting it, along with the SwiftData interoperability path.

`UserDefaults` handles preferences, the Keychain handles tokens and credentials, and the file system handles documents and caches. Offline-first design closes the module: local store as source of truth, sync, conflict resolution and CloudKit for cross-device.

The polish that makes an app feel like it belongs on the platform. Implicit animation with the `.animation` modifier, explicit `withAnimation`, transitions, phase and keyframe animators, and `matchedGeometryEffect` for hero-style movement between screens.

Gestures cover tap, drag, magnify and rotate, plus composition and simultaneous recognition. Advanced SwiftUI closes the module: `Canvas` for custom drawing, custom `Layout` conformance, scroll transitions and `scrollTargetBehavior`, `visionOS` and widget awareness, and `UIViewRepresentable` for the UIKit interop every real app eventually needs.

The capabilities that only exist because the app is on Apple's platform. Push notifications through APNs and the UserNotifications framework — permissions, categories, actions, rich content and notification service extensions.

StoreKit 2 covers in-app purchase and subscriptions with the modern async API and transaction verification. App Intents expose features to Siri, Shortcuts and Spotlight; WidgetKit adds home-screen and Lock Screen widgets; and Sign in with Apple, `LocalAuthentication` for Face ID and Touch ID, Universal Links, and the App Tracking Transparency and privacy-manifest requirements close the module.

Tests that hold up as an app grows. Swift Testing is taught as the default for new code — `@Test`, `#expect` and `#require`, parameterised tests, traits and tags, and its async and parallel execution model. XCTest is covered as the framework you will still meet in existing projects.

Test design gets real attention: dependency injection for testability, fakes and protocol-based test doubles, testing async code and actors, and testing SwiftUI view models. XCUITest covers UI automation, page-object structure, launch arguments for deterministic state, and reducing flakiness.

Measuring before optimising, using the tools Apple ships. Instruments for time profiling, allocations, leaks and the SwiftUI instrument that shows which views re-render and why — the fastest route to fixing a sluggish screen.

Launch-time optimisation, main-thread blocking, list and image performance, and the SwiftUI-specific traps around identity and unnecessary body evaluation. Memory work covers leaks, retain cycles and the memory graph. App size closes the module — asset optimisation, on-demand resources, App Thinning and bitcode-era build settings.

The part that blocks more first-time iOS developers than any language feature. Certificates, identifiers, provisioning profiles and the signing model explained rather than memorised, plus automatic versus manual signing and resolving the failures each produces.

App Store Connect covers app records, build upload with Xcode Cloud or `xcodebuild` and `altool`, TestFlight internal and external testing with beta review, and the App Store submission flow — screenshots, metadata, privacy nutrition labels, age rating and export compliance. Common rejection reasons and phased release close the module.

Full-time capstone work followed by structured interview preparation. You build and ship a complete iOS application — SwiftUI throughout, Observation-based state, structured concurrency, a URLSession data layer with SwiftData offline storage, push notifications, an App Intent or widget, tests, and a TestFlight build real people can install.

Interview preparation matches Pune iOS panels: a Swift language round covering optionals, value semantics and ARC, a concurrency round on actors and Sendable, a SwiftUI round on state and identity, and a mobile system-design round. Resume, LinkedIn and GitHub polish included.
