When we find ourselves listening for events, reacting to those events, and then going back to listening for more events, we have ourselves an Event-Loop. Having an event-loop is a common scenario. So common that Apple decided to provide us with a model...
Read More...Apple provides many useful network frameworks. Network.framework (you can check my previous article on Network.framework if you want to see an example) is the latest. But sometimes we need to go deeper, and the abstractions might get in the way. In...
There are many reasons to use more than one programming language in a project. In some cases, a lot of work has gone into building a framework (years maybe). Rewriting the whole framework to have the codebase in the same programming language, might...
Read More...Apple's network APIs are many, the older APIs are well documented, and you'll find lots of examples. Not so much about the new Network framework. One factor might be that the name is not that search-friendly. In this post, I'll explain how to use the...
With advances in the frameworks and tools we use to develop software, creating a new app seems like magic. We just click a few buttons, and everything is created for us. I enjoy magic, but I think that sometimes we end up being Framework "users" without...
Read More...An essential step before you deliver your application to your users is to make sure that your app is not overusing your user's resources. In this post, I'll show how to use Xcode's visual debugger and the command-line counterparts to check for common...
Read More...Getting the screenshots of your app doesn't need to be complicated, and it shouldn't require you to install additional applications to do it. Sure you can use any other third-party library, but sometimes simple is better. Also, it is always fun to...
Read More...At some point on your app development career, you'll find yourself working with text fields to get some data from the user. Collecting data from the user sometimes involves additional work than merely reading text from an UITextField. For example,...
Read More...Building a command-line interface (CLI) tools is a complicated task. We work on the logic of our application and also have to deal with other details like parsing parameters, handling the correct display directives depending on the TTY, etcetera. Vapor...
Read More...Swift is a powerful language. It can be used to create command-line tools, iOS apps, watch OS apps, macOS apps and server-side applications. However, sometimes, we only need to complete a small task, maybe do some automation on our local setup or build...
Read More...If you decided to create an Extension for your app (maybe a Today Extension), you will quickly find out that you need to access data from your main app. And soon after, you will find out that you can't access files in your main app directly from the...
Localization is not only translating content but adapting the content to culture, language and customs. This makes our apps more intuitive and engaging for our users. We can localize not only text, but we can also localize images, sounds, shortcuts...
