Sandbox support

Sandbox-enabled applications cannot load from any directories other than those that have been preconfigured.

See the image below to see the directory where reading can be configured.

User Selected File

In order to monitor directories other than the above, you need to set Read Only to User Selected File and implement the following.

func selectObserveDirectoryAndSaveBookmark() {
    // ref: https://stackoverflow.com/questions/12153504/accessing-the-desktop-in-a-sandboxed-app
    let openPanel = NSOpenPanel()
    openPanel.canChooseFiles = false
    openPanel.canChooseDirectories = true
    openPanel.canCreateDirectories = true
    openPanel.begin { [weak self] result in
        guard result.rawValue == NSFileHandlingPanelOKButton else { return }
        let bookmarks = openPanel.urls.compactMap { try? $0.bookmarkData(options: .withSecurityScope, includingResourceValuesForKeys: nil, relativeTo: nil) }
        let defaults = UserDefaults.standard
        defaults.set(bookmarks, forKey: "observe_bookmarks")
    }
}

func observeSelectedDirectories() {
    let defaults = UserDefaults.standard
    let bookmarks = (defaults.object(forKey: "observe_bookmarks") as? [Data]) ?? []
    let bookmarkURLs = bookmarks.compactMap { try? URL(resolvingBookmarkData: $0, options: .withSecurityScope, relativeTo: nil, bookmarkDataIsStale: nil) }
    bookmarkURLs.forEach { $0.startAccessingSecurityScopedResource() }
    let observer = ScreenShotObserver(searchDirectoryPaths: bookmarkURLs.compactMap { $0.relativePath })
    observer.delegate = self
    observer.start()
}
