(UI Testing with Swift) Failure getting list of active applications: AX error -25205

Our tests were working perfectly, but for no apparent reason (checked the commits), the UI tests simply stopped to work in the simulator (haven't tested on a device yet). Every time it needs to perform an action on an UI component (like tap() or typeText("string here")) we get the error in the title, Failure getting list of active applications: AX error -25205.

Here is the log from the point everything goes wrong:

    t =    13.57s             Find: Elements matching predicate '"TextFieldUsuario" IN identifiers'
    t =    13.74s             Assertion Failure: UI Testing Failure - Failure getting list of active applications: AX error -25205

I've found people with similar problems, however none of them seems to have found a solution to our case:

Result 1:

https://forums.developer.apple.com/thread/47696

Solution: Installing El Capitan and updating Xcode; we are already in El Capitan, and our Xcode is the latest version according to the App Store app.

Result 2:

iOS UI Testing : Failure getting list of active applications: AX error -25205

Solution: None of the answers give a solution.

Result 3:

UITesting Failure getting list of active application

Solution: "Enable UI Atomation" on the device (Settings > Developer). It's already enabled in the Simulator.

My Xcode version is 7.3.1 (7D1014) and the OS X version is 10.11.4 (15E65).

Somebody knows how to solve that problem? Maybe updating El Capitan to the latest version?

Thanks to matt I could find a solution. It seems to be a bug with Xcode 7.3.1. Downgrading to Xcode 7.3.0 solved the problem.

EDIT: In case anyone is looking for Xcode 7.3.0 for download, you can find it here: https://developer.apple.com/download/more/

[Mobile_iOSUITests.LoginViewControllerUITest testLoginComSucesso]

appeared to be the real cause. Are you sure if you're invoking correct method as there is a typo in the method name testLoginComSucesso?

Exception is thrown because of following

[NSObject(NSObject) doesNotRecognizeSelector:]

It appears as if your's LoginViewControllerUITest does not recognised the method
