Learn web development fast: https://shop.killervideostore.com/ Mobile app development has moved toward hybrid apps, using the web stack (HTML5, CSS3 and JavaScript,) and frameworks like Phonegap or React Native. But when it comes to the development of high demand (in terms of performance) mobile apps, using native languages like Swift for iOS and Java for Android is still the way to go. This might change with Googles Flutter framework. https://flutter.io/ https://facebook.github.io/react-native/ https://phonegap.com/ CLARIFICATION AND UPDATE: 1. Swift and native development will only diminish IF Flutter (or something like it) meet expectations. 2. I group React Native, Phone Gap etc ... simply because they are not one of the two native languages. 3. IF Flutter fulfilled expectations, then the move from native (Java, Swift) would happen over time. 4. I suggested in the video that Swift would die ... bad word. I should have said diminish considerably. The chances of Swift dying completely is pretty much 0% ... since apple is behind it and it seems to me, that there might always be a situation (but more rare over time) where native is required. Remember that slower hybrid becomes less slow with each new generation of smartphone. 5. I don't believe is identifying as a Java developer, Swift developer, JavaScript developer ... or any type of developer. Be a developer who uses any and all languages on a need to nerd basis.
