I’ve mentioned a number of WatchKit resources most recently a tool for generating Apple Style activity indicators for use with WatchKit.

You may have noticed with WatchKit that performance drops quickly on the Apple Watch when your WatchKit app has a lot of data performance drops quickly.

Here’s a tutorial from Robin Senior of the score explaining how you can structure your code in a way that it increases the performance of your app, and reduces the complexity of your app’s architecture through the use of view models.

The tutorial shows step-by-step how to create your view models, and minimize traffic by performing only necessary updates, and display that information within a table.

You can find the tutorial over on theScore tech blog.

A nice guide on improving WatchKit app performance.
