Raywenderlich website has covered quite a bit of mobile development with the latest technology. But it is not truly complete nor covers everything. I am hoping that, which is what I am looking forward to, Ray could have some of the other authors to fulfill the quests, which are Java for android development, Java language, Reactive for mobile development, Javascript language, react tutorials, Xamarin for mobile development, C# language. Seven books in total.
This pretty much fulfill or covers all the mobile development technology.
