Whilst there are no many different solutions to getting apps on to the various Apple devices (Unity, Corona, Codea, Xamarin, HaXe, Cocoon, Cordova etc etc) sometimes there's no getting away from the fact that if you want the best native experience, access to all the latest tools, libraries, and features then you have to go direct to the source and use the tools that were originally intended.
Over the various iterations of the OS the libraries and functionality of the Apple devices (and by extension XCode) have increased in power, scope & ease of use.
Although the addition of the higher level libraries like UI Kit, Sprite Kit, Watch Kit, Auto layout etc have increased the range of what is achievable (and what is knowable) significantly they have actually made app development (especially the simpler types of app) easier and more accessible to a wider audience.
Don't be put off by the interface, you don't need to understand everything and in a lot of cases the default options are sufficient.
Get a good book or a video course on iOS development.
Work slowly and steadily, create simple apps and make each successive app build on knowledge gained on the previous one.
