Xcode 8 Beta - Convert to Current Swift Syntax Failed: Could not find test host

Question

I am receiving an error message when I try to use Xcode 8\'s Convert Wizard. After trying rebooting, downloading fresh code, and deleting my DerivedData files I cannot esc

Answer 1

This worked for me:

1. Select the Xcode project in the lefthand browser.
2. Click on your test target in the Project's General tab.
3. Disclose "Testing". In my project the "Host Application" pulldown button was blank. Select your appropriate host application.
4. Try building your test target now. If that succeeds then converting syntax should as well.

I had this problem after installing the Xcode 8 beta so I assume this is related.
