AS3 was based in ES4 specification,"superseeded" by ES5.So ActionScript was in fact pretty opened and could have been today's javascript. I dont think one can compare AS3 and Swift. In fact Microsoft had it's own implementation of ES4, Jscript.net. > Flash is now relegated to a "second-choice" technology for web applications, "Thanks to" Steve Jobs,that didnt want anyhting on his plateform he couldnt control. IOs is a closed ecosystem,IOs has more developpers and apps than ever.There is nothing to learn here but the fact that they control their plateform,from end 2 end,and users keep on coming.
