# 通过自动创建的Bridging header 导入的Obj-C 类，Bridging header 似乎找到了但Swift 类不会

Question

1. I added the files directly to my project from finder to Xcode.
2. Bridging header was automatically created by Xcode.
3. #import the Class into the Bridging header - no issues on the Bridging Header.

4. I try to instantiate Class var into swift class - " use of undeclared type " error shows up.

   • Notes: When I try to COMMAND + click on the #import I get the message "Symbol Not Found".

Answer 1

You need to have your bridging filename set to the "Objective-C Bridging Header" field under the Swift Compiler section in Build Settings for it to be included by the Compiler.

"Symbol Not Found" is just an Xcode bug, I get that but I have no issues using bridged files.

Answer 2

Turns out that file ( A.swift ) that was trying to reference the "other file" ( B.swift ) had " test target membership " selected! So I either had to add the "other file"( B.swift ) to the test target membership or remove file ( A.swift ) from the test target membership. I hope that makes sense and that it is of help to someone.
