Don't trust your eyes when looking at weak pointers
We have some really old piece of code. It’s basically a proxy for an NSTimer retained by the timer instead of our precious View Controller that shows the PDF file.

Pen was the main tool in that app. In our testing, we found that quite often the palm laying on the iPad screen would produce some touches. Our code didn’t know if a…
UIBandSelectionInteraction vs. UICollectionViewCell background color
One of my colleagues (kudos, Nik) added the proper support of the pointer at iPad OS during our Ship It days (approximately once a month we can do any feature/improvement we want). After some time the team jumped in and we all were preparing it for release. When it came to QA, we’ve got a strange ticket: file list view in Select mode would sometimes deselect all previously selected items. I…
A sad story about Swift Equatable
