💬 풀이

let n = readLine()!.components(separatedBy: [" "]).map { Int($0)! }
let (a, b) = (n[0], n[1])

var s = ""
for _ in 1...b {
 for _ in 1...a {
 s += "*"
	 }
 s += "\n"
}

print(s)

💬 더 나은 방법?

let n = readLine()!.components(separatedBy: [" "]).map { Int($0)! }
let (a, b) = (n[0], n[1])

for _ in 0..<b {
 print(Array(repeating: "*", count: a).joined())
}
