Facebook and Parse have created a library of low-level code called Bolts for iOS and Android designed to speed up developing mobile applications.
Parse is a service that provides components for developers as well as frameworks so mobile developers can do things like push notifications easily without managing back-end infrastructure. Facebook acquired Parse, a Y combinator company started in 2011, last year. Parse was created to ease the frustration that goes with native development in iOS and Android.
The Bolts library is available to download and developers can drop the code into projects without a Facebook or Parse account. Parse has tiers for service, including a free one, another for developers making money on accounts and an enterprise-class version.
In a nutshell, Bolts allows asynchronous code to be more easily organized and managed.
Parse noted that there will be more Bolts on the way.
