swift - Iterate Array 30 times using For loop -

-

i have array 8 elements want copy elements 1 one until count of new array reach 30 times.

i used loop , while result copying first element 30 times.

    let myshift = ["d12","e","n12","n","off","rest1","rest2","d"] var myarray = [string]() in myshift { while myarray.count != 30 {     myarray.append(i)    }}

i read examples map tried use didn't work.

since it's not clear looking for, here 2 options.

this 1 repeat contents of array until reaches 30 items in total. keep order , loop them. results in array 30 elements.

let myshift = ["d12","e","n12","n","off","rest1","rest2","d"] var myarray = [string]() (0..<30).foreach {   myarray.append(myshift[$0 % myshift.count]) }

this 1 result in array each element repeated 30 times, total of 240 elements.

let myshift = ["d12","e","n12","n","off","rest1","rest2","d"] let array = [[string]](count: 30, repeatedvalue: myshift).flatmap { $0 }
