Is Swift Pass By Value or Pass By Reference

Question

I\'m really new to Swift and I just read that classes are passed by reference and arrays/strings etc. are copied.

Is the pass by reference the same way as in Objecti

Answer 1

It is always pass-by-value when the parameter is not inout.

It is always pass-by-reference if the parameter is inout. However, this is somewhat complicated by the fact you need to explicitly use the & operator on the argument when passing to an inout parameter, so it may not fit the traditional definition of pass-by-reference, where you pass the variable directly.
