Xcode 8 Beta - Convert to Current Swift Syntax Failed: Could not find test host
This worked for me:
- Select the Xcode project in the lefthand browser.
- Click on your test target in the Project's
General
tab. - Disclose "Testing". In my project the "Host Application" pulldown button was blank. Select your appropriate host application.
- 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.
