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 processValue(depth: Int) -> String {
var result: String = "The depth is "
result += String(depth
return result
}
print(processValue(depth: 31))
