Branch observation-beta-shared-state-syncups not compiling for watchOS

[Malauch]

Description

I was checking new shared state changes on observation-beta-shared-state-syncups branch and noticed that here is a problem which prevents compiling for watchOS:

swift-composable-architecture/Sources/ComposableArchitecture/Observation/SharedState/SharedPersistence/FileStorage.swift

Lines 4 to 10 in 43f0c25

	#if canImport(AppKit)
	import AppKit
	private typealias Application = NSApplication
	#elseif canImport(UIKit)
	import UIKit
	private typealias Application = UIApplication
	#endif

UIKit can be imported on watchOS but UIApplication is not available. Unfortunately it is not easy fix as adding additional type alias for WKApplication. It was added in watchOS 7 and TCA supports watchOS 6. I know that branch is work in progress but decided to share this just in case.

Hi @Malauch, that branch is a non-released and non-publicized experimental branch. Some of those findings may never see the light of day. We may get around to fixing the watchOS problem, but no promises. And you are free to open a PR against the branch to fix the problem.

Since this is not an issue with the currently released library, I am going to convert this to a discussion.
