Icon fonts have been around for a long time and of course they have been available to iOS apps ever since support for custom fonts was introduced. However, being able to use something and having it available in a usable wrapper are two different things. This library from Ignacio Romero Zurbuchen looks like it should make working with these fonts a pleasure. With the ability to automatically generate enums, produce images from the glyphs and some helpful UIKit extensions, it looks great.
Filip Radelic with a look at the slightly hidden API for animating UIVisualEffectView from blurred to clear. One that mystery is solved, he then hooks it up to UIViewPropertyAnimator and it all works as expected. Amazing to think that in iOS 7 we didn't even have access to the blur API at all.
What do you do when find a bug in UIKit? You file a radar of course! But then what? Maybe you find a workaround and fix it yourself. Things get annoying when the bug gets fixed in a new iOS release though and suddenly your code includes fixes that are only sometimes needed. This library encapsulates fixes for some UIKit bugs which have been fixed in iOS 10 and nothing gets executed if it's not needed. 👍
Bolot Kerimbaev on the neural networking APIs in Accelerate and Metal. There's some good background information here followed by an example of BNNS and a comparison of the APIs. Interesting stuff.
