In a throwback to Apple’s Think Different campaign, the icon used by OS X for Swift files, Apple’s new programming language. Swift documents have the file extension ‘.swift’.
The code seen in the icon makes reference to the iconic speech, with functions named ‘heresToTheCrazyOnes’ and ‘villify(troubleMaker: NSObject)’. The code also generates collections of ‘misfits’, ‘rebels’ and ‘troublemakers’.
OS X icons often include references to this speech, with both the Notes and TextEdit apps on Mavericks including the speech in a scrawled form in their icons. Sadly, these references appear to have been removed in OS X Yosemite, as part of Apple’s refocusing on icon clarity and simplicity over highly-detailed assets.
