Cannot cast App Delegate to App Delegate in Tests

Question

I'm doing Unit Tests in Swift, and am running into a problem. Every time I run the tests, I get the error:

Could not cast value of type 'app.AppDelegate' to 'app_Tests.AppDelegate'

I made sure that the AppDelegate was unchecked from the tests bundle, and the view controllers cannot access the app delegate anymore. Does anyone have a solution to this problem. Thanks in advance!

I think your view controllers has checked target membership in your test bundle. In this case you view controllers uses your tests module and App Delegate your real module.

If you have in your test file @testable import <module name> in the top, where your app name, for example app. Then you should have ability to your view controllers without checked target membership for your tests.

This thing comes with Swift 2.0 that was released in September 2015.

I have tried your solution.But if I have written method in my viewcontroller(ex:func getEmail()) means I could not call that method in my test.How to call those method in test target. – Madhumitha Jul 01 '16 at 09:31
should that method be a public method? – Madhumitha Jul 01 '16 at 09:34
@Madhumitha nope, `@testable import` mean you could use internal methods, too. But not private. – Alexander Zimin Jul 01 '16 at 13:02
