I have just been learning Swift for days.
I am making a project, that is a smart calculator (like Casio) in iOS.
I had some experiences in Pascal, so I am wondering:
1 - what is the replacement of the "readln" code in Swift? (that let the computer receive the data in which user inputed to)
2 - how can I make a program, which can link the button in the first Page view to the Option Page View, to work on some features like calculate the stretch and the perimeter of rectangle, etc.?
