Facebook, creator’s of React Native, use the platform for a number of production applications.
ComponentKit puts a unique spin on describing and building a user interface:
“It lets you focus on what your UI should look like, not the steps necessary to build it. It emphasizes a one-way data flow from immutable models to immutable components that describe how views should be configured. It does the heavy lifting of building a view hierarchy from this description.”
This is a powerful concept, moving from code specific statements (e.g layoutSubviews) to more a more generic idea such as “stack these UI elements, one atop the other.”
SwiftyAs provides similar functionality to the as? operator in Swift, allowing for safer type casts. So how is this accomplished in Objective-C? Tom Adriaenssen:
“SwiftyAs introduces a category on NSObject, providing a readonly block property taking a Class and returning an id. The class represents the desired type.”
Apple has released another round of beta’s for Xcode 6.3 and iOS 8.3.
Changes includes Objective-C nullability qualifiers for better interoperability with Swift as well updated documentation in Xcode assertions in Swift.
“CATweakerSense is an Xcode plugin that makes working with CAMediaTimingFunction more visual.”
CATweakerSense integration is very nice, put your cursor/caret on a CAMediaTimingFunction and it will show an overlay of the actual time curve. As a bonus, you can adjust the curve adjust it on-the-fly and immediately see the results.
