If you work on a Swift project that follows the Model-View-ViewModel (MVVM) architecture or similar, you may want to jump to counterpart in Xcode from your view to your model, and then to your view model. (ie. by using Ctrl+Cmd+Up and Ctrl+Cmd+Down).

You can do this in recent versions of Xcode by setting a configuration default.

From a terminal, just type this command and press Enter:

defaults write com.apple.dt.Xcode IDEAdditionalCounterpartSuffixes -array-add "ViewModel" "View"

	class ShopFilterParams: NSObject, Codable, DictionaryMapping {

	private var config: [String: Any]?
	private var defaults: [String: Any]?
	private var list: [String: Any]?

	var showAreaFilter: Bool?
	var showServiceFilter: Bool?
	var defaultAreaId: String?
	var defaultService: String?

	//For empty fields there will be no "Select All", so we need to check

	//My solution is to cancel the navigation and load the request with loadRequest: again. This will be come the similar //behavior like UIWebView which always open new window in the current frame.
	//
	//Implement the WKUIDelegate delegate and set it to _webview.uiDelegate. Then implement:
