✓ Helpers
2.isEven
// true
3.isOdd
// true
✓ Helpful enum for code readability:
// Before:
if (number % 2 == 0) {
print("even")
} else {
print("odd")
}
// After:
switch number.parity {
case .even:
print("even")
case .odd:
print("odd")
}
// Before:
if (numberA % 2 == numberB % 2) {
print("both numbers have the same parity")
}
// After:
if (numberA.parity == numberB.parity) {
print("both numbers have the same parity")
}
