=== Noncompliant code example

[source,swift]
----
func isOdd(x:Int) -> Bool {
  return x % 2 == 1  // Noncompliant; if x is negative, x % 2 == -1
}
----

=== Compliant solution

[source,swift]
----
func isOdd(x:Int) -> Bool {
  return x % 2 != 0
}
----
or

[source,swift]
----
func isOdd(x:Int) -> Bool {
  return abs(x % 2) == 1
}
