Boutique Best Practices

Use this skill when migrating to Swift 6, troubleshooting concurrency issues, setting up tests, or following Boutique's recommended patterns.

Swift 6 and @MainActor Isolation

Boutique's Store, StoredValue, and SecurelyStoredValue are all @MainActor isolated. In Swift 6 with strict concurrency, this means:

• All store operations (insert, remove, removeAll) must be called from a @MainActor context.
• Controllers that use @Stored, @StoredValue, or @SecurelyStoredValue are implicitly @MainActor since the property wrappers are @MainActor.
• SwiftUI views are already @MainActor, so no extra annotation is needed there.

Calling store operations from non-MainActor contexts
