无法从测试目标中看到Swift类

I have an iOS app using both ObjC and Swift code. I tried setting up a test target for it today with no success. I have a single test case class written in Swift. I imported my app's module there. I made sure the classes I am trying to access are public. But I cannot see them from my test target. I can see ObjC code from there though.I have an iOS app using both ObjC and Swift cod
