Bug: Can't Update the wallpaper

[NghiaTranUIT]

Description

There is a notice that Artify is unable to update a wallpaper if the main screen is not active.

How to reproduce

1. Get Feature photo
2. While fetching the photo, we active different window screen.
3. When it it's finished, there is no update.

Acceptance Criteria

• Able to update the the wallpaper regardless of any active window.

After devoting couple hours to investigate why Artify couldn't override the wallpapers for all spaces, it turns out that

artify-macos/artify-core/artify-core/Services/WallpaperService.swift

Lines 89 to 95 in 0e4f198

	NSScreen.screens.forEach {
	if let url = NSWorkspace.shared.desktopImageURL(for: $0),
	url.absoluteString != payload.1.absoluteString {
	isApplied = true
	try? NSWorkspace.shared.setDesktopImageURL(payload.1, for: $0, options: [:])
	}
	}

NSScreen.screens only returns the physical screens, not the number of "spaces".

Preliminary effort

From OS < 10.7, macOS stores wallpaper datasource in com.apple.desktop.plist. Otherwise, it stores in ~/Library/Application Support/Dock/desktoppicture.db

This approach is capable of overriding the specific wallpaper for all spaces, but it requires to relaunch the Dock (killall Dock), which I'm super discouraged.

Beside that, editing the desktoppicture.db directly could be potential risk when the database's structure changes. Consequently, it's corrupted.

Thus, I leave this bug here.
