As a sometime Apple developer I do welcome this. Hopefully it will legitimise some of the grey (non-official) toolchains and support the development of tools and community that much of the rest of the software development world enjoys, and people won&#x27;t be tied solely to Apple&#x27;s own dev tools.<p>Does anybody else think it&#x27;s a little strange though? To have open source tools solely to target a closed platform? I haven&#x27;t used Swift myself but from what I&#x27;ve seen it seems to be something like Javascript with libraries for iOS, perhaps with a few semantic adjustments. Would that be a fair assessment?<p>I can&#x27;t imagine it being used for much else beyond developing for iOS devices. Perhaps Macs. So while it&#x27;s free as in &quot;beer&quot;, but could it truly be said to be free as in &quot;speech&quot; in any substantial fashion?
