Entry Point (_main) undefined. for x86_64 architecture - only for Xcode UITesting

Question

I get this error only when trying to run UITests. I do not use a storyboard, and creating the application is fine, and unit testing works fine.

• In my AppDelegate app, I have @UIApplicationMain
• I do not have storyboard files or links to the storyboard file in my info.plist.
• tried to clean / restore, restart xcode

Even the UITests entry works great and can open the application. It is simple when I try to run actual tests to get an error.

Perhaps I am missing a target somewhere or do you need to add something to XCUIApplication start args? Any ideas?

Answer 1

Since unit tests worked, I compared each line in the Binding section of the Build Settings section for both unit tests and user interface tests.

The following are the things I changed to start testing the UI:

• In the package loader bundle, I had to add $ (TEST_HOST)

• In Mach-O Type, which was installed in the executable, I had to change it to Bundle.
