Eject is an open source tool allowing you to transition a UI built within Xcode’s interface builder into Swift code.
The Interface Builder is fantastic for laying out an interface, but it can become a hindrance as your interface becomes more complex and dynamic. With Eject you can translate your Xibs into source code with support for constraints, outlets, labels and more.
While you don’t get code that compiles straight out it definitely makes for a fast start.
You can find Eject on Github here.
A handy tool for those taking an interface builder layout and turning it into code.

Keyframes is an open source tool and library from Facebook that allows you to convert Adobe After Effects shape based animations to a format which can then be loaded by the included library on both iOS and Android.
Keyframe images are vector based so they can be resized without losing image quality, feature very high quality animations with great detail, and a small file size. Keyframes was designed because engineers wanted to display Facebook reaction animations with maximum animation detail on a wide variety of devices.
You can find more about Keyframes over on the Facebook code site.
In addition to Adobe After Effects you will need the Adobe ExtendScript Toolkit.
You can find Keyframes on Github here.
A great tool for creating iOS animations.
