ios - Swift - Error calling a function from another function -

-

this question has answer here:

while following apple's book "the swift programming language"

i ran across issue while working on "experiment - write function calculates average of arguments." first chapter.

to determine average of set of numbers, want reuse sum of numbers [setof(numbers: int...)] function , divide count of numbers [numbers.count]. receiving error: 

could not find overload '__conversions' accepts supplied arguments

when try call sumof(numbers) averageof(numbers) function.

what should change call sumof(numbers) function correctly, averageof(numbers) function? 

func sumof(numbers: int...) -> int {     var sum = 0 //0     number in numbers {         sum += number     }     return sum  //651 } sumof(42, 597, 12)  //651  func averageof(numbers: int...) -> int {     var sum = sumof(numbers) //issue in line     return  sum / numbers.count } averageof(42, 597, 12)

paste code above new xcode 6 playground recreate.

error screenshot (i need 10 reputation points before can post image.)

you're passing different type function expects. apparently int... not same int[].

you create override accepts int[] , returns sum.
