Opening New Windows Programmatically in macOS with Swift

If you're developing applications for macOS and want to create new windows programmatically, you're in the right place! This guide breaks down how you can open new windows with custom sizes and styles using Swift. You might be looking for a way to enhance your application with dynamic window creation without relying on storyboards. Let’s explore how to achieve this effectively.

Setting Up Your macOS Application

The first thing to understand is how to structure your macOS application correctly. This involves two parts: creating the main app delegate and implementing the window management and creation logic.

Creating the Main Application Delegate

We'll first dive into the simplified AppDelegate class. This is where the initial window is set up, and from here, we can also open new windows.

Creating a New Window Class

Now that we have our main window set up, let’s create a new class that will manage the new windows. This class, NewWindowController, will be responsible for creating and customizing new window instances.

Summary

In this guide, we have learned how to create and manage multiple windows programmatically in a macOS app using Swift. The steps we followed include:

Setting Up the Main App Delegate: Here, we loaded the main window and added functionality to manage user actions (like button clicks).

Creating a Window Controller Class: We created a dedicated class for handling new window instances, with the potential for customization.

This approach gives you control over window creation behavior, allowing you to dynamically adapt your user interface based on your application's needs. Now, you can easily extend these examples to include pop-ups, modal views, or any additional UI elements that enhance your app's functionality.

Whether you're building a complex application or a simple utility, having the ability to create new windows programmatically will significantly improve your application's interactive capabilities. Happy coding!
