Question

iOS

The question is, I wrote an application for Android (the simplest one, interacts with the server via api) - for clients. Where to start so that I can write the same for iOS? Where to read?

Answer 1

1 Set up a working environment. Buy a poppy, install xcode, buy a developer account.
2 Read lessons for example Beginning Objective-C .
3 It is advisable to complete the examples from these lessons, teach how to create controllers, place buttons, labels, pictures and tables on the form.
4 Look at the android application, map the screens. Read the guides from apple so that the application does not contradict them.
5 Start implementing the application.
