50 Tools And Resources For Swift Programming

You might be hearing more buzz about Apple’s new Watch product lately, but the company also announced a new programming language in 2014 — their first in at least decade.

The language, Swift, is touted as something that’s easier to follow, learn and develop in than the much older Objective-C language, which has its origins in the even older C language, and which is also influenced by the Smalltalk language. There is speculation that Swift is meant to replace Objective-C; however, Apple has essentially said otherwise. For now, at least, Swift can live alongside Objective-C code. However, if you are already developing or are thinking of developing iOS mobile apps and Mac OS X desktop/ laptop-based software, it never hurts to stay on top of new programming language developments — especially for a language like Swift that may one day replace Objective-C.

Even were Swift not to end up replacing Objective-C, it has features and abilities not available in the latter that are worth exploring — such as custom operators, command-line scripting, functions as first-class citizens, Playgrounds and much more. In fact, Swift Playgrounds are particularly useful for educators teaching students to code.

In less than a year since Swift’s reveal (WWDC 2014, June), there are already numerous tools and resources. To make it easier to find what you need, we’ve compiled a list of various tools and resources that are useful for developing iOS mobile apps in Swift — although many of the resources apply to Mac OS X software development as well.

NOTES:

  • When using your favorite Web search engine to find Apple Swift resources, keep in mind that there is not only another programming language named Swift (for parallel programming) but it is also a protocol used by the banking industry.
  • Swift is a very young programming language. When Apple released a beta version during 2014’s WWDC conference, they stated that the final version (released Sep 9, 2014) would not necessarily be compatible with pre-1.0 version code. So code published in tutorials written for Swift that were published before the official release date may produce errors with the latest version of Xcode and Swift. Swift is still a work in progress and is subject to change, so try to stick to tutorials written in late 2014 (Oct-Dec) and later. (At time of writing, Swift is at version 1.2.)
  • For the reason above, use older Swift tutorials cautiously. If you get errors, it’s possibly due to more recent Swift language changes.
  • IAP = In-App Purchase – a paid feature/ service available from within an iOS app.
  • IDE = Integrated Development Environment.
  • At time of writing, there were nearly 20,000 Swift repositories on GitHub.com.
