Introduction In the previous chapter, I started talking about the video game creation process, from project setup to adding the background. Now, I’m going to add the player and physics to it. You can download the project here. First Step The first step is to initialize player using SKSpriteNode, set up player.position, and add player as a child node. SKSpriteNode - is an onscreen graphical element that can be initialized from an image or a solid color. ...

Introduction I have never tried creating a game before; it feels like magic to me. I know that games have an enormous amount of underlying layers of abstractions and tools such as game engines, rendering, and so on. I have always been eager to learn at least 1% of the game creation process. In this article, I’m going to explore step-by-step instructions for creating a game for the iOS platform using SpriteKit. ...

Introduction When working in a large codebase with a significant number of async events, I often found myself in situations where I couldn’t combine events effectively. This resulted in optimization problems and inefficient consumption of OS resources. The codebase contained closures and async/await, so it wasn’t possible to use operators like merge or combineLatest. After discovering this limitation, I decided to add new methods using Combine. I will be demonstrating this with a simple NetworkService responsible only for executing and validating requests using Combine. Let’s dive into the implementation. ...

Introduction I always wondered how I could automate testing the push notification process. Even when Apple introduced the possibility of dragging a configured file to the simulator to display a notification, it is still a manual process. I’ll skip testing via the terminal because I think it takes more time than using an APNS file or the RocketSim app. Before I was first introduced to the RocketSim app, I used an APNS file for testing push notifications. It worked for me and my teammates, but I knew it could be better. It looks something like this: ...

Introduction If you start a project from scratch, you need to always create some kind of service like PushNotificationService that will be responsible for handling push notification events. In this article, I want to explore a simple implementation of PushNotificationService to be able to reuse and customize it in future projects. First Step The first step is to add the Push Notifications capability to your project. Go to your project -> Signing & Capabilities -> Tap + Capability -> Search for Push Notifications. ...
