There is much useful information in the iOS Human Interface Guidelines, but we’ll focus on the App Icon section where Apple describes technical requirements and makes recommendations on a design.

Now it’s time to create! Of course, if you don’t have even more questions along the way… What size a canvas should be? How to use grids? How to export an icon? It’s time to go deep into the technical part and find answers. Phew! That’s what we should pay attention to when developing an app icon. Sometimes it’s enough to adjust the size, but in some cases it’s better to make more changes. It doesn’t mean you need to draw different app icons rather, big differences will reduce app recognition.

IOS (on the left) and Android (on the right) icons of the same apps Look, how small app icons are in Settings! Therefore, it’s important that an icon maintains its legibility regardless of size. That’s the point, and the user can’t stretch it to examine. Let me tell you about them by drawing on the experience and using beautiful headlines. They are a number of aspects that we need to take into account. Not at all! Popular applications often use logos in icons: Twitter, Medium, Reddit and others. It doesn’t mean a logo can’t overlap with an icon. However, it’s not a logo.Ī logo and an app icon have different goals, ways of using and requirements respectively. And that’s not surprising! An app icon is a piece of branding. There are a lot of articles on the topic and most of them relate to Paul Rand’s design principles. Now it assists in the search for the app on the Home screen among other icons. When the user installs an app, the icon’s goal changes. It confuses and casts doubt on the benefit of an app. At the same time, a bad icon does twice as much, but the other way around. A good icon generates interest, provide confidence, assure the user that an app might be useful for him. At this stage, the user decides if he wants to find more about an app if not - he scrolls further. It’s the first users see when they find an app on the App Store and Google Play. Well, let’s get started! Why every app needs an iconĪn app icon is a unique image added for every mobile application. I decided to write this article to help the same beginners as I was, but I hope that experienced designers will find it useful too. I found answers on some of them only after a couple of completed projects. When I faced the challenge of drawing an app icon for the first time, I had a lot of questions. It’s a great responsibility, and it depends on a designer if an icon can cope with that. When we run our rasterizer from the command line with swift run, we get this pretty icon:īesides paths, we can also use shapes to compose our icon.Despite the small size, an icon promotes an application in the App Store and Google Play, presents the user with it and also helps to find it on the Home screen after installation.

If you cloned ConsoleUI, at this point you should be able to run the following commands: The generated project and target files don’t need to be committed to your repository, but you can do it if that makes it easier for later use. Add your view to the macOS target (target Foo on the screenshot below).Generate an Xcode project ( swift package generate-xcodeproj).To allow for realtime previews follow these steps: Xcode does not support live previews on Swift packages yet (FB8979344). If you do this, you’d probably want to follow the steps on the README file from that repo, or refer back to my first article on this topic.

Feel free to begin with an empty project too. You can start by cloning my ConsoleUI repo, which I have updated today to run on Xcode 12.4 with the latest SwiftUI available. Today, I’m writing about generating application icons for iOS with SwiftUI. I wrote Generating Social Media preview images with SwiftUI and GitHub Actions so other people like you could do it too. Last December I used this same technique to generate social media preview images for this blog.

I published the code in GitHub at ConsoleUI. I couldn’t resist using SwiftUI from the command line, and I wrote about it in Rasterizing SwiftUI views from the command line to showcase how to generate static images (PNG, JPEG, etc). While the main goal for SwiftUI is to build rich user interfaces on iOS and other Apple platforms, it can also be used to do other fun things.

SwiftUI was introduced to the world at WWDC in June 2019.
