Promises is a modern framework that provides a synchronization construct for Objective-C and Swift to facilitate writing asynchronous code. Typically, async operations take a completion handler in a form of a block, which is called to provide either a result or an error.

Often such nesting becomes painful to follow or modify. ...

XMPPFramework provides a core implementation of RFC-3920 (the XMPP standard), along with the tools needed to read & write XML. It comes with multiple popular extensions (XEP's), all built atop a modular architecture, allowing you to plug-in any code needed for the job.

(And it won't block the main thread at all). There have been a number of changes to the public API of XMPPFramework in an attempt to improve the ergnomics and safety when used with Swift. ...

Each onboarding experience is comprised of two primary components, the background and the content pages. The background includes the static background image/video, the page control, and the skip button. The content pages are made up of four pieces, an image/icon, title, body, and action button. Create individual pages by creating instances of OnboardingContentViewController. Provide a title, body, image, text for an action button, and within the action block handle whatever you want to do...
