Creating a Framework for both iOS and watchOS

The try! Swift app runs on both iOS and watchOS, and I’d like to expand it to support fancy extensions and possibly something with iMessage. While I was ok duplicating the Model layer between the two platforms initially, as more extensions and platforms are something I want to code quickly on, it was time to move that code out into a framework.

Swift 3.0 Refactoring Cues

I’ve been upgrading the try! Swift app to Swift 3.0 for what feels like 3 days now. But anyway, this morning my BUILD SUCCEEDED!! And although the process was definitely frustrating, a lot of the things that needed fixing were very repetitive and a good opportunity to refactor...

The Easy Button: A Fancy Animation with StackView

Last week, I spoke at and attended iOSDevCampDC, where I had the pleasure of listening to @atomicbird‘s great talk on StackViews. I knew StackView basics, but I had no idea how easy it is to create some impressive-looking animations with them!

Xcode 8: How To Create an Animated iMessage Sticker

I've finally have little bit of time set aside this weekend to work on a fun side project. Ever since I saw my friend @chiuki's Fit Cat app on the Android Watch, I knew I needed to have it on my Apple Watch and @chiuki agreed to let me make it. Of course when I started my new project, I opened the Assets Catalog, and was immediately tempted to create Fit Cat stickers. After all, wouldn't it be fun to share these with your friends?!!!
