Swift - How do I check if switch case contains an value

Question

I'm trying to do something like that

var name = "Thiago Valente"

switch name {
case .contains("Valente"):
   return "Hello, My surname is like your"
default:
   return "Hi ;)"
}

The contains don't exists, so it is possible to do with switch case? ( I know it's simple to do with if-else )

Answer 1

You can use the let x pattern, followed by a where clause:

var name = "Thiago Valente"

switch name {
case let x where x.contains("Valente"):
   return "Hello, My surname is like your"
default:
   return "Hi ;)"
}

Normally let x will match every value, but you say more specifically what kind of values you want to match in the where clause.
