Why can't Xcode find my App for Unit Tests?

Question

I'm fairly inexperienced in iOS. I wanted to write Unit Test for my Cocoapods Project.

My ViewControllers that I want to test are in Pods. When I want to write a unit test, I already receive an error message with import MyApplication

which says

No such module 'MyApplication'

Note that I used "MyApplication" only as a substitute for orginal name I crossed out in red in the picture.

What is the issue?

EDIT:

code of my test class:

import UIKit
import XCTest
import Pods_MyApplication_Example

@testable import Pods_MyApplication

class Tests: XCTestCase {

    override func setUp() {
        super.setUp()
        // Put setup code here. This method is called before the invocation of each test method in the class.
    }

    override func tearDown() {
        // Put teardown code here. This method is called after the invocation of each test method in the class.
        super.tearDown()
    }

    func testExample() {
        // This is an example of a functional test case.
        XCTAssert(true, "Pass")
    }

    func testPerformanceExample() {
        // This is an example of a performance test case.
        self.measure() {
            // Put the code you want to measure the time of here.
        }
    }

}

To create a test target, on the test navigator, I click on the '+' and then choose 'New Unit Test Target'

I am sorry if there are any information missing. I will add those if there are any!

EDIT2: Changed picture which might provide more information

You must use @testable import to import your app's module for unit testing. You have to supply the name of your application target, Pods_MyApplication_Example, not the name of the project. In your example it will look like the following:

@testable import Pods_MyApplication_Example

And remove the import statement that imports the app target.
