I pay for my license myself, and this post is simply written as a guide to learning more about a tool that I find very important in the iOS Developer toolbox. Networking is an essential part of modern […]

When you perform a URL Request in your app, you typically configure the request in your code and when it’s all set up you pass it off to a URLSession data task, and the request should succeed if everything goes as expected. When the request is misconfigured, the server will hopefully return a useful error […]

In the past two weeks I have introduced you to Combine and I’ve shown you in detail how Publishers and Subscribers work in Combine. This week I want to take a more practical route and explore Combine in a real-world setting. A while ago, I published a post that explained how you can architect and […]

One of the topics that I could write dozens of posts on is networking. Making calls to a remote API to retrieve or persist data is something that is a key feature in many apps that are currently in the App Store. Some apps make extensive use of the network while others only need the […]

Both networking and protocols are topics that I could write dozens of posts on, and I would still have more ideas and examples left in my head. In today’s article, I would like to combine the topics of networking and protocols and explain how you can design a robust networking layer for your app, that’s […]

When your app shows images from the network in a table view or collection view, you need to load the images asynchronously to make sure your list scrolls smoothly. More importantly, you’ll need to somehow connect the image that you’re loading to the correct cell in your list (instead of table view or collection view, […]

I know that it involves configuring my request to be multipart, that I need to attach the picture as data and there’s something involved with setting a content […]

Modern applications often rely on data from a network connection to work as intended. Sometimes they rely heavily on the network and are almost worthless without an internet connection while other apps can function mostly fine without a network connection. What these apps have in common is that they contain code that might be challenging […]
