How to create a pointer in Swift? -

i'm working swift 3.

i have c syntax :

int myvar; int *pointer = &myvar; 

so modifying pointer or myvar same exact same thing. don't know if makes difference, in case myvar array containing elements of class , pointer pointer 1 element of array.

(assuming understand you're asking for....)

try following code in playground. should print "99" 3 times.

class row {     var rownumber = 0 }  var rows = [row]()  let testrow = row() testrow.rownumber = 1  rows.append(testrow)  let selectedrow = rows[0] selectedrow.rownumber = 99  print(testrow.rownumber) print(selectedrow.rownumber) print(rows[0].rownumber) 

by default, there's no copying of objects part of assignment statement. if struct, different.

adding bit completeness:

if want similar effect scalar values instead of objects, swift supplies various types of wrappers.

let intpointer = unsafemutablepointer<int>.allocate(capacity: 8)  // should 1, not 8 according comment re: docs let other = intpointer other.pointee = 34  print(intpointer.pointee) 

(warning: haven't used these wrappers except experimenting in playground. don't trust without doing research.)
