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.
If you are a mobile app developer or interested in getting into designing apps and you haven’t heard of ThemeKeeper Elements,this post is for you.
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.
If you want to code a mobile app, you need to know a programming language. But it can be hard to choose the best language (or languages) for a project. There are a lot of options out there, and in this post I’ll help you narrow them down so that you can pick the best.
In this post, we’ll look at advanced uses of encryption for user data in iOS apps. We’ll start with a high-level look at AES encryption, and then go on to look at some examples of how to implement AES encryption in Swift.
In this tutorial, I’ll show you how to use a powerful yet elegant on-device database solution for your iOS apps: Realm Mobile Database. An alternative to Apple Core Data or SQLite with object-relational mapping (ORM), Realm Mobile Database offers developers an easier and more natural way to store and query data.
When you’re first getting started with mobile development, it can be hard to choose a platform. Even worse, each platform has its own set of languages and tools to choose from. So how can you decide?
That was quite the keynote. Don’t you think? Nobody knew what to expect, due to the absence of rumors or leaks. But I think Ispeak for many Apple developers when I say that it was a great keynote.
Any app that saves the user’s data has to take care of the security and privacy of that data. As we’ve seen with recent data breaches, there can be very serious consequences for failing to protect your users’ stored data. In this tutorial, you’ll learn some best practices for protecting your users’ data.
In my recent course Go Further With Swift, I showed you how to code a functional iOS weather app with live weather data, custom UI components, and some slick animations to bring everything to life.
