Note

Apple will reject apps that are using private url schemes (Ugh, Apple....) if they are pretty much obvius. Some apps are rejected and others are not, so, be aware of this issue before implementing any of those URL's in your app as a feature.

Updates

• [UPDATE 4] iOS 10 update: apparently settings now can be reached using App-Pref instead of prefs
• [UPDATE 3] For now you just can use url schemes to open your apps's settings with Swift 3.0 (Xcode 8). I'll keep you informed when OS preferences can be reached
• [UPDATE 2] The openURL() method of UIApplication is now deprecated. You should use application(_:open:options:) instead
• [UPDATE 1] Not yet tested in iOS 10. It will fail because of policies changes in URL scheme handling.

Rapid prototyping with Relay

Relay makes data fetching in React apps simpler, by letting you declare the data needs of your components instead of writing complex imperative code. React, Relay, GraphQL and the other complementary tools are changing how apps are built.

Advanced React.js Performance

Performance is one of the reasons why React.js is so popular for building complex, highly interactive web applications. It became the go-to library for developers who don’t like to make compromises for technical reasons when building awesome user experiences. However even with React.js it still can be easy to hit it’s performance limits.

In this lightning talk Daniel will go beyond the basics of shouldComponentUpdate and immutable data structures and will discuss how to correctly instrument, measure and optimize performance in complex React apps. He will help you understand the overhead of different parts of the React component lifecycle, how some of it’
