I manage to use below work around.
let count = 1
switch count {
case 0, 1:
let buttonId = NSAlertThirdButtonReturn
let shouldFallthrough = { () -> Bool in
switch buttonId {
case NSAlertFirstButtonReturn:
print("do something")
case NSAlertSecondButtonReturn:
print("do something")
case NSAlertThirdButtonReturn:
print("do something")
return true
default:
fatalError()
}
return false
}()
if shouldFallthrough { fallthrough }
default:
print("do extra things")
}
