I have been using Qt for many years in Linux. I am trying to learn to develop Mobile Apps using Qt, especially for IOS. I have never done this before,

Can someone please help me with following questions? Thanks.

(1) Do I need a MacBook to develop IOS Apps? Or can I just use my existing CentOS desktop so I don't need to buy a Mac machine.
(2) Is there a good tutorial? I have been doing google search but have not found a useful demo.

Thank you
