问题
I added a bridge header to my app the other day because I was trying to add Objective-C files to my Swift project. I was having trouble getting the connection to work(and I also did not know how to implement the Objective-C files), so I decided I wanted to start over again. I deleted the Objective-C files and the Bridge-Header file and now I am getting an error saying:<unknown>:0: error: bridging header '/Users/CalebKleveter/Documents/Development/iOS/personal/swift/Projects/Dicey/Dicey/Dicey-Bridging-Header.h' does not exist
回答1:
Go to Build Settings of your project, find Objective-C Bridging Header row and remove its contents.
回答2:
Go to targets file->Build Settings->Swift Compiler - General, delete the contents in the same line as Objective-C Bridging Header
