Question

func bigSquare (hei1: Int, wid1: Int, hei2: Int, wid2: Int) -> String {
var balc1 = hei1 * wid1
var balc2 = hei2 * wid2
if balc1 > balc2 {
return String("Apartment A")
} else {
return String("Apartment B")
}
}

print(bigSquare(hei1: Int(readLine()!)!, wid1: Int(readLine()!)!, hei2: Int(readLine()!)!, wid2: Int(readLine()!)!))

Because there are two string inputs but you are taking as four integer inputs

Do this:

import Foundation

let apa = readLine()!
let ap1 = apa.components(separatedBy: ",")

let hei1 = Int(ap1[0])!
let wid1 = Int(ap1[1])!

let apb = readLine()!
let ap2 = apb.components(separatedBy: ",")

let hei2 = Int(ap2[0])!
let wid2 = Int(ap2[1])!

print(bigSquare(hei1: hei1, wid1: wid1, hei2: hei2, wid2: wid2))
