This Swift code contains one error – can you select the line that is incorrect?
Tip: You should mentally run the code from top to bottom, meaning that if line 3 says an integer should be returned and line 10 tries to return a string, line 10 is the wrong one.
func printLetterHeads(copies: Int, name: String) -> String {
var output: Int = ""
for _ in 1 ... copies {
output += "\(name)\n"
}
return output
}
print(printLetterHeads(copies: 27, name: "Paul Hudson"))
