How to zip arrays in Swift?

Question

let array1 = ["Albert","Bobby"]
let array2 = ["Charles", "David"]

How do merge two array so that the out put would be ["Albert", "Charles", "Bobby", "David"]

Do you only want to zip arrays of the same type? Do you ever want to zip more than one array? Will the arrays ever have a different number of elements in each? — nhgrif, Mar 28 '16 at 12:21
you can get your output easily, if you take first elements from both array and add it to new array .. like wise in for loop — Moin Shirazi, Mar 28 '16 at 12:24

You can use zip to combine your two arrays, and thereafter apply a .flatMap to the tuple elements of the zip sequence:

let array1 = ["Albert","Bobby"]
let array2 = ["Charles", "David"]

let arrayMerged = zip(array1,array2).flatMap{ [$0.0, $0.1] }

print(arrayMerged) // ["Albert", "Charles", "Bobby", "David"]

Give this a shot

   var a = ["one", "two"]
   var b = ["three", "four"]

   var c = a + b
   print(c)

This isn't what is being asked. Reread the question. – nhgrif Mar 28 '16 at 12:19
