TIOBE Index for July 2014

July Headline: Swift enters TIOBE index at position 16

Apple's new programming language Swift enters the TIOBE index at position 16. Everybody is curious to know what this new language is about. Especially because it has been developed by Apple. But will Swift remain in the top 20 after its first peak of popularity? Do you remember Google's Go language a couple of years ago? It was a hype as well after its first release and even became programming language of the year in 2009. But as soon as everybody realized that Go was more of the same, it dropped out of the top 100 for some time. Swift seems to be a different story though. The language itself is also nothing new, but in contrast to Go it serves a purpose, i.e. to supersede the outdated Objective-C language. New applications for iPhone and iPad will all be written in Swift eventually. So Swift will probably stay in the top 20 for a long while and has the potential to become a top 10 player.

The TIOBE Programming Community index is an indicator of the popularity of programming languages. The index is updated once a month. The ratings are based on the number of skilled engineers world-wide, courses and third party vendors. Popular search engines such as Google, Bing, Yahoo!, Wikipedia, Amazon, YouTube and Baidu are used to calculate the ratings. It is important to note that the TIOBE index is not about the best programming language or the language in which most lines of code have been written.

The index can be used to check whether your programming skills are still up to date or to make a strategic decision about what programming language should be adopted when starting to build a new software system. The definition of the TIOBE index can be found here.

Bugs & Change Requests

This is the top 5 of most requested changes and bugs. If you have any suggestions how to improve the index don't hesitate to send an e-mail to tpci@tiobe.com.

  1. Apart from "<language> programming", also other queries such as "programming with <language>", "<language> development" and "<language> coding" should be tried out.
  2. Add queries for other natural languages (apart from English). The idea is to start with the Chinese search engine Baidu. This has been implemented partially and will be completed the next few months.
  3. Add a list of all search term requests that have been rejected. This is to minimize the number of recurring mails about Rails, JQuery, JSP, etc.
  4. Start a TIOBE index for databases, software configuration management systems and application frameworks.
  5. Some search engines allow to query pages that have been added last year. The TIOBE index should only track those recently added pages.
