I'm a beginner of XCode and I am currently studying this app in south Korea. How can I get data (images, pictures and so on..) used in this app?
The easiest way to get downloads related to XCode is through the Apple website. I recommend visiting the website then click through the available tabs to obtain information regarding the resources. As far as I know, once you install XCode you will have the possibility to use some example resources to get your started, then you can add additional files.
XCode homepage: https://developer.apple.com/xcode/downloads/
