Feature flags in SwiftUI can be set up using a typed FeatureFlag enum with per-flag defaults, combined with local and remote providers orchestrated by a composite provider and an @Observable FeatureFlagManager for controlled rollouts.

The best way to override feature flags during iOS debugging is by using an optional in-app debug UI that allows developers to toggle flags in DEBUG builds while preserving safe local defaults for production.

Yes, remote config supports gradual rollouts and A/B testing in macOS apps by using a RemoteFeatureFlagProvider that overrides local defaults across devices and user segments without requiring code changes.

A composite feature flag provider works by merging local defaults with remote overrides, ensuring that SwiftUI apps always have a safe fallback while fetching the latest remote configuration for active experiments.

No external dependencies are needed to implement thread-safe feature flags in SwiftUI, as the system uses built-in providers, an @Observable manager, and SwiftUI environment support to ensure testability and thread-safety natively.

You should avoid a composite provider for feature flags if your app requires only static local defaults without remote overrides, as the remote fetching layer adds unnecessary network complexity for simple configurations.
