Swift from Apple is a programming language for Cocoa and Cocoa Touch. Swift code can work side-by side with Objective-C.
Swift is expressed in a clean syntax which means the APIs are easy to read and maintain. Modules provide namespaces and eliminate headers, the code is less prone to mistakes, and memory is managed automatically.
The following is a list of how-to and tutorial content that matched your search term. ProgrammableWeb's how-to content comes from two sources; full-blown tutorials that we publish ourselves and other highly relevant tutorials that we find elsewhere on the Web. This list represents on combination of both tutorial types and if you go to ProgrammableWeb's API University, you'll not only be able to find more, they are organized based on your role (API providers or developers who consumes APIs). If you know of a tutorial that would be of interest to the ProgrammableWeb community, we'd like to know about it. Be sure to check our guidelines for making contributions to ProgrammableWeb.
When Apple open-sourced Swift, developers saw a greater potential for the language than mere client-side iOS development. The community envisioned a language that could become more universal and cross-platform, evidenced by the emergence of server-side Swift powered by the Vapor Web Framework.
Using the open source CareKit framework, developers can create apps that help users monitor and manage medical conditions and their overall health, and then share that data with healthcare pros. Here we run through the CareKit modules and how the pieces fit together, using sample Swift code.
In this article we take a look at the features of LocationKit, a replacement library for iOS’ CLLocationManager and Android’s LocationManager. We explain how LocationKit can benefit location-aware mobile apps, and take you through the process of setting up and using LocationKit in your own app.
Code signing is one of those frustrating chores that iOS developers inevitably have to deal with--whether it’s creating provisioning profiles or managing development or production certificates or certificates for push notification. It’s tedious, frustrating and convoluted, but it doesn't have to be.
