I'm developing a watchOS companion app for my iOS app in Xcode 26.0.1 on macOS Sequoia. The watch app uses a simple ObservableObject class with @Published properties for state management, which compiles fine for iOS but fails for the watchOS target. Error: Initializer 'init(wrappedValue:)' is not available due to missing import of defining module 'Combine' Code: swiftimport SwiftUI import WatchConnectivity import Combine // Added explicitly class WatchConnectivityProvider: NSObject, ObservableObject { @Published var distance: Double = 0 @Published var isActive: Bool = false // Additional @Published properties... } Environment: Xcode 26.0.1 (17A400) macOS Sequoia watchOS deployment target: 11.0 Apple Watch Series 11 running watchOS 11.6.1 What I've tried: Adding import Combine explicitly Cleaning build folder Verifying target membership This same code pattern works in the iOS target Is @Published / Combine supported differently in watchOS under Xcode 26? This code worked in previous Xcode versions. What's the recommended approach for observable state in watchOS apps with Xcode 26?
