How to create a Section Background in a UICollectionView in Swift

I recently faced a small challenge on a UICollectionView, the following screenshot illustrates pretty well the situation. In short: I needed to have a transparent background in a UICollectionView to be able to see through some sections, but I didn’t want to be able to see the background in between the cells on some others.

Simple UICollectionView pagination with API and Realm database

If you’re using Realm database and a REST API, you may have encountered a pagination issue at some point. That’s what happened in the project I’m working on. Something was wrong with the pagination and I kept adding variables and ifs until I couldn’t remember what was doing what. Then I realized I needed a clean slate, and I created this little project. So, this is a mockup to test a minimum viable pagination and preloading of data from a REST API to feed a UITableView or UICollectionView, using database. Just to make things clear, I am not introducing pagination into … Continue reading Simple UICollectionView pagination with API and Realm database

Swift Tips #1: Extra padding problem on UITextView?

Sometimes when you integrate a design, you need things to be square, everything aligned: buttons, title, images, textView… But wait, what’s that extra padding on the UITextView? You may have tried to print the contentOffset or contentInset without success. That’s not it. However, all your problems can be solved in one line, and here it is: // magic line for a UITextView named textView textView.textContainer.lineFragmentPadding = 0 I wouldn’t call it exactly straight forward, so this is a memo for me and tip for you :)
