To program a sidebar in Xcode, you'll typically use Swift and SwiftUI or UIKit, depending on your project type. For a SwiftUI app, you can create a sidebar using a NavigationView with a List for the sidebar content, and use NavigationLink for navigation. In a UIKit app, you can use a UISplitViewController or a custom UIViewController layout to create a sidebar. Don't forget to set up the appropriate constraints and connections in Interface Builder if using UIKit.
Yes C or C++, although the programing environment is unlike the Mac and Xcode because of the interface. On Mac it is much easier, but still takes skill.
if you mean make an app, buy a mac, get Xcode, learn how to program objective C (cocoa touch) get a dev lisence, release it on the app store :)
