any way to chain == and || operands

Question

I have a situation where I have to make a check like this:

if foo == a || foo == b || foo == c {
  //do stuff
}

is there any way to chain these operands into something smaller like IDK foo == a||b||c

What about a switch statement? switch foo { case a, b, c: // do something default: break } — crashoverride777, May 20 '16 at 15:37

Try this:

if [a, b, c].contains(foo) {
   //do stuff
}

I ain't no swift expert but if this creates some sort of container then tests that container contains something, then you've sacrificed performance for the sake of a few characters of typing. Or does some sort of compiler optimise this out? – Bathsheba May 20 '16 at 11:32
@Bathsheba basically you make an array, and search the item in the array, yes it reduces performance – 4oby May 20 '16 at 11:39
