A neat little blocks-based Objective C wrapper for the Instagram API.
It readily parses the JSON responses on a background thread and does the dirty work for you so you just have to deal with Instagram model objects. Built atop AFNetworking.
Check out this lovingly crafted Apple Music-style popup library. SPAlert is written in clean, beautiful, modern Swift code by Ivan Vorobei, a prolific and talented open source developer.
This open source project contains a ton of preset styles, including "done," "heart," "message," and more. If the presets don't fit your needs, you can customize the popups with custom images and duration. Includes support for light and dark modes, and installable via Swift Package Manager and CocoaPods.
