I have a simple Swift project with RxCocoa and RxSwift on the cocoapods. When one of the files has

import RxSwift

I get "No such module" error. If I run the app on the simulator it goes away but there is no autocomplete like this and it makes it really hard to start working with RxSwift.

Expected outcome:

Helpful autocomplete

What actually happens:

There is no autocomplete

You can do like this
import RxSwift
import RxCocoa

class LoginViewController: UIViewController {
@IBOutlet fileprivate var tfUsername: UITextField!
@IBOutlet fileprivate var tfPassword: UITextField!
@IBOutlet fileprivate var btLogin: UIButton!

var disposeBag = DisposeBag()

override func viewDidLoad() {
    super.viewDidLoad()

    let usernameControlProperty = tfUsername.rx.text
    let usernameValid = usernameControlProperty.orEmpty
        .map { (string) in string.characters.count >= 5}
        .shareReplay(1)
    // ...
 }

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}

}

I think this issue related to Xcode rather then library 😜

I'm not sure what to do with this.

All of our unit tests are passing.

I can understand how malfunctioning autocomplete can be frustrating, but this is not an issue with this project. If it compiles, it's valid Swift code.

As far as I can tell, it does work for fresh projects, so there is maybe something in your configuration that is wrong.

I would suggest trying to create more public pressure on Apple to fix their toolchain, although even that tactic will probably fail.

¯\_(ツ)_/¯ , sorry
