How to make a custom relational operator in Swift


I am working with Doubles that have a range of 0..<360. I want to create a switch statement that will have 8 cases. A case for 0, 90, 180 and 270, and a case for the values in between. It seems that the half-open operator will not satisfy what I'm trying to do here. I'm thinking the solution may be to create a custom relational operator. Let's call it <..<
case 0:
case 0<..<90:
case 90:
case 90<..<180:
case 180:
case 180<..<270:
case 270:
case 270<..<360:
I've looked into creating a custom infix operator that returns a Boolbut that won't work because the arguments would only include the lhs and rhs.
How can I accomplish this?
Your switch is unnecessarily complicated. See if this works for you:
let value: Double = 180
switch value {
case 0:
print("exactly 0")
case 0..<90:
print("less than 90")
case 90:
print("exactly 90")
case 90..<180:
print("less than 180")
case 180:
print("exactly 180")
case 180..<270:
print("less than 270")
case 270:
print("exactly 270")
default:
print("less than 360")
}
