I'm happy to announce the release of my LinkedIn Learning course "Swift 5: Protocol-Oriented Programming." https://www.linkedin.com/learning/swift-5-protocol-oriented-programming/
A property wrapper lets us define property access patterns that can be applied repeatedly. What does that mean? In essence, the property wrapper is a data structure that provides controlled access to the property that uses it as a wrapper. In this article, I show you how to define a property wrapper and how to apply it. I'm also going to show you a practical example of using property wrappers. Alright, let's dig in! To define the most basic property wrapper, create a structure, class or enumeration and mark it using the @propertyWrapper attribute: @propertyWrapper struct Box { } [...]
Alright, so here are five tips that can make your Swift code look more professional. Tip#1 Follow Apple’s naming conventions. If you have worked with other programming languages, it might be tempting to use the naming and coding style you’re used to. However, Swift has its own naming rules, so do your best to apply them. As the saying goes: “When in Rome, do as the Romans do.” Apple provides more details and examples in their API design guidelines. The bottom line is this: name your protocols, functions, types, properties, methods, variables, parameters so that their purpose is [...]
If you want to create an iOS app that stands out, the least you could do is to give it a custom look and feel. Let’s say that you want to start by changing the background color of your UIViews to dark gray. You may be tempted to switch to your storyboard, and change the background color of each UIView in the “Attributes Inspector.” Not so quick! There’s a better and easier way to provide a custom color scheme/branding for your app. UIAppearance lets you customize the views and controls consistently across the entire applications. It’s elegant and straightforward, [...]

Smart homes, self-driving cars, Siri, Alexa - some typical examples of how machine learning and artificial intelligence have become part of our daily life. Wouldn't it be cool to understand the concepts behind these complex topics? In my book Machine Learning with Core ML 2 and Swift, I'm going to familiarize you with common machine learning tasks. We'll focus on practical applications, using hands-on Swift code examples. You're going to develop smart apps, like this flower recognizer: How about building an Amazon review analyzer from scratch? I'll show you how to do it! And there's a lot more. We'll delve [...]

Woohoo! My latest course "iOS Development: Architecture" is now available on LinkedIn Learning: https://www.linkedin.com/learning/ios-development-architecture and on Lynda.com: https://www.lynda.com/iOS-tutorials/iOS-Development-Architecture/699340-2.html
https://youtu.be/LdIib-SrOmk The transcript of the video If we need a URL, we initialize it using the following syntax: var url = URL(string: "http://www.leakka.com") That’s pretty straightforward, but wouldn’t it be cool to create a url just like this: var url = "http://www.leakka.com" ? If we tried that, we’d get a compiler error. Actually, we can make it work with just a little bit of coding. And here’s how! Swift has a protocol called ExpressibleByStringLiteral. If we make a type adapt it, we can create instances of that type from a string. Here’s the official documentation: https://developer.apple.com/documentation/swift/expressiblebystringliteral ExpressibleByStringLiteral A type [...]
