Xcode 10.2 - Use of undeclared type Result

Question

I have downloaded Xcode 10.2 beta release. I am trying to use new Result type in Application project or Playground with Swift 5 enabled.

My code is as below:

import UIKit

enum SampleError: Error {
    case foo
}

func bar() -> Result<Int, SampleError> {

}

When compiling I am getting:

Use of undeclared type 'Result'

I have double checked settings and verified with below code that I am using Swift 5.0

    #if swift(>=5.0)
    print("Hello, Swift 5.0")
    #endif

Does anybody encountered similar issue?

Where is `Result` declared? The compiler says it's not declared at all. — vadian, Jan 27 '19 at 20:54
@vadian As it was [added to the stdlib "in Swift 5"](https://github.com/apple/swift-evolution/blob/master/proposals/0235-add-result.md), karmel seems to be expecting it to be declared there. — jscs, Jan 27 '19 at 21:23

Update:

Result is now available with Xcode 10.2 beta 2 release. Yay

Here is the link to release note where you can find more details about Swift changes.

Ouch, I missed that! Good point! I was so excited after reading all those articles that I thought it will be available with that release and missed checking the notes. Thanks! – matrejek Jan 27 '19 at 20:58

Actually, since 10.2 beta2 was released, your link now redirects to beta2 release notes page, which does mention `Result` type. @karmel, I think you can download beta2 and try your code again there. – pckill Feb 13 '19 at 15:15
