let age = 22
let sex = “girl”
if (sex == “girl” && age >= 18 && age <= 25){
print(“girl”)
} else {
print(“Go you”)
}
A new syntax has been added for us in swift2: if case
if case 18…25 = age {
print(“free”)
} else {
print(“without”)
}
You can add conditions through where
Of course it is not needed, swift2 provides us with the syntax of conditional filtering: where
if case 18…25 = age where sex == “girl”{
print(“Yes, Old Iron”)
} else {
print(“Let’s go”)
}
[swift] if case, guard case, for case
