Using PHLivePhotoView with Auto Layout

So, I was working on updating my app Memories to support displaying Live Photos properly and not just as a static image. I took a look at the documentation for PHLivePhotoView and thought that this would be fairly straightforward. For Live Photos, I’ll just use a PHLivePhotoView instead of a UIImageView.

Podcast sponsorship - an experiment

I’m an iOS developer in my spare time. You know, on evenings, and weekends. I recently launched an app called Memories. I created the app mainly because it was an app that I wanted to have.

It involved just a simple date comparison, ignoring time, and without crossing timezones. »

Using stride to convert C-style for loops to Swift 2.2
