Answer 1

1.Click on the test file(unit test or UI test file) 2.Go to right panel and You'll see target membership. 3.Select Unit test and all would be good to go.

Answer 2

Prefix func name with test

Also try changing the targets

Answer 3

There is two way to check it.

1. If you have multiple scheme, In top of Xcode, make sure you choose Test to run the test.

2. Click on your test class, then click right panel. In target membership, checklist the tests target.

Answer 4

In case you disabled indexing earlier,

1. Close all Xcode and Simulator instances

2. Delete this setting

   defaults delete com.apple.dt.Xcode IDEIndexDisable

3. Restart Xcode

This should reenable indexing and should bring back the individual test button (diamond shaped) in the subsequent Xcode launch.

Answer 5

A possible answer for some - I had added a new scheme in my XCode, but the tests were only in the original scheme. Switching back to the original scheme re-instated my tests.

Answer 6

My issue was file was not included in the workspace. If not included, go to finder and drag and drop to that folder.

Answer 7

In Xcode 12.4 just Command+U or menu Product > Test and all buttons in your XCTestCase will appear again.

Answer 8

Solution that is working for me in Xcode 13 , SWIFT 5 :

Open another Xcode file and then open the file wth your function again, the button should appear then.

Answer 9

I just re-started my Xcode and it worked. as everything was set-up the way it should be !!

Answer 10

Prefix func name with test

example test function name:

 secondExample() must be **testSecondExample()**

then clean the build file use this shortcut key command + shift + k

Answer 11

Need More description? But Try following troubleshooting... check Target Membership of test file

Answer 12

Go to,

Xcode > Window > Projects

click on the delete button for derived data. Close XCode and open again. You should be good to go.
