hi, i read as well the apple "Getting Started" Resource at this url "goo.gl/TZVGUz" i learned many things from it , but its not a complete resource for ios development. i found a "Swift Language Tutorial" at the apple resource , (1000 pages) , and its a good resource for learning swift. but i'm not found a good resource for learn fully ios and xcode... for you understand my mean, in the swift tutorial books, there is not any resource for how to make "Vibration" or not a resource for how to use/create 3d Touch. i hope you understand my problem. i need a best book/website for learn the ios development. please help me , how can i start the ios developing ? please introduce a best and top ios development book. thanks a lot !
