We live in an imperfect world. It isn't always practical to throw out all your Objective-C code and start over. Framework authors (including Apple) are even more constrained: lots of apps aren't 100% Swift and won't ever be. Making the next version of Photos.framework only available to Swift is a non-starter.
What's a . . .
For the most part the new Photos.framework is a refreshing replacement for the old Asset Library interface. It was so clearly built to handle the massive (and every increasing) size of photo libraries.
There are a few sore spots. The first is annoying but minor: The title that Photos displays for an individual . . .
A new beta means a new compiler. Check out the official release notes for more information.
- Lots of compiler crashes have been fixed.
- You can use
#if swift(>=x.y)checks to gate the use of compiler features. This should finally make it possible to have a single branch support multiple versions of Swift . . .
The bug fixes continue to come flooding in. As always, get the full details in the official release notes.
- Failable and throwing initializers can both exit before initializing all stored properties or calling
- Nested C structs now import as nested Swift structs
@objcis now valid on enums . . .
Early Christmas Present
You may have heard already but Swift is now open source! As of 9:09 AM PST the site is still choking under heavy load but the associated github repos are now public.
Grabbing the source:
brew install cmake ninja. Create a main directory to hold all the associated repos, then clone:
git clone . . .
Supporting the Pencil
I'm happy to finally be able to share what I've been working on: supporting the Apple Pencil.
In this post I want to cover the basics of supporting
UITouchType.Stylus, some conveniences to make it easier to support iOS 8 and iOS 9.0, and a hole in the current processing of events in iOS that can make supporting the Pencil . . .
Leaks is a filthy liar
This is a blog post I started many months ago and never got around to finishing; please forgive any outdated screenshots or references. The core ideas are still relevant so I'm gonna go ahead and post it. The bug in UIKit that confused Leaks into missing the cycle was supposedly fixed but a good Software Engineer . . .
