Shared SwiftUI App Workflow

Create a multiplatform Xcode project with shared SwiftUI code targeting both iOS and macOS. Configure separate schemes and build settings per target, use SPM or CocoaPods for dependencies, and establish per-configuration environment variables to manage platform-specific requirements and code signing.

Choose between MVVM or The Composable Architecture (TCA) for state management in multiplatform SwiftUI projects. TCA provides more structured, testable state handling for complex workflows; MVVM offers simpler patterns for straightforward apps. Both integrate with shared code across iOS and macOS targets.

Configure Xcode Cloud workflows to automate testing and build processes, then route successful builds to TestFlight for beta distribution. Define per-target schemes, environment variables, and code signing certificates to enable end-to-end automated deployment across iOS and macOS.

Yes. SwiftUI multiplatform projects support both Swift Package Manager and CocoaPods for dependency management. Use SPM for Swift packages and CocoaPods for Objective-C libraries; resolve dependencies via Package.resolved and maintain separate dependency configurations per target as needed.

Xcode's debugger, memory profiler, and performance instruments work on both iOS and macOS targets. Debug shared SwiftUI views using Xcode previews, set platform-specific breakpoints, and use Instruments to profile CPU and memory usage across your multiplatform app.

No. Create a native multiplatform Xcode project with separate iOS and macOS targets sharing SwiftUI source code without Catalyst. Catalyst is optional if you need to run an iOS app on macOS; native multiplatform projects provide better performance and platform integration.
