Swift by Robin Eggenkamp This site collects a lot of learning resources and news about Swift. If you click on it, Xcode displays the debug area right below the editor area. This tutorial is an introductory explanation and breakdown of Swift. It publishes in-depth videos every week that showcase and discuss solutions to problems developers encounter while building projects in Swift. In terms of number of hours, I would say at least 20 to get some of the fundamentals down. The behaviour of the app is still the same. It's easier than you thought, right? If you have a domain, you can use your own domain name. I don't want to scare you away from learning programming. You can view the Object library in two difference modes: list view and icon view.
