The main purpose of a digital signature is to verify the integrity of some information. For a simple example, let’s say you had a file that was transferred over the network and you want to check that the entire file was transferred correctly. In that case, you would use a checksum.
In my previous post in this series, I wrote about the Model-View-Controller pattern and some of its imperfections. Despite the clear benefits MVC brings to software development, it tends to fall short in large or complex Cocoa applications.
You have worked weeks or months on your first iOS application, and you are ready to submit your masterpiece to Apple’s App Store. How do you do this? Is your application ready for submission? I am sure that some of these questions have entered your mind at one point or another.
In the previous tutorials, we took a look at the Realm Platform as well as the on-device Realm Database for iOS. In that post, you learned how to synchronize your app data locally as well as in the cloud. While this presents a complete solution for many developers, you may want to do more than just persist data, but also run server-side logic.
MVC stands for Model-View-Controller, and it’s a widespread architectural pattern for software development. It’s the de facto design pattern for Cocoa development, and it has been for many, many years. Most of us can’t imagine building applications without it. Both UIKit (iOS) and AppKit (macOS) make frequent use of MVC. It almost seems as if we don’t have another option to build applications for iOS, tvOS, macOS, and watchOS.
Coding an iOS app is hard work, so it makes sense that devs want to cut corners and find ways to get their app online as quickly as possible. But a successful app will be around for a long time—that means years of bug fixing, feature enhancements, and working with other coders.
In this tutorial, you’ll be learning about the CocoaPods dependency manager and how to implement it in your app. We’ll go through the steps from creating an Xcode project all the way to importing frameworks. Along the way, we will learn about some basic Terminal commands and what they do.
Firebase is a cross-platform real-time mobile database platform that allows coders to focus on what they do best—coding their apps—without having to worry about DevOps concerns like server infrastructure and database modeling.
In this post we’ll build a simple game from scratch. Along the way, we’ll touch on some of the most important aspects of the SpriteKit library.
