unwrapping multiple optionals in if statement
option-type, swift
Solution
Great news. Unwrapping multiple optionals in a single line is now supported in Swift 1.2 (XCode 6.3 beta, released 2/9/15).
No more tuple/switch pattern matching needed. It's actually very close to your original suggested syntax (thanks for listening, Apple!)
if let email = emailField?.text, password = passwordField?.text {
}
Another nice thing is you can also add `where` for a "guarding condition":
var email: String? = "baz@bar.com"
var name: String? = "foo"
if let n = name, e = email where contains(e, "@") {
println("name and email exist, email has @")
}

Problem
I want to unwrap two optionals in one if statement, but the compiler complaints about an expected expression after operator at the password constant. What could be the reason? ``` if let email = self.emailField?.text && let password = self.passwordField?.text { //do smthg } ``` Done in Swift.
