Using the VP3300 SDK with Swift requires a bridging header to allow the application to have a mixed-language codebase
First, you will need to create a header file. Right click on your project directory and click "New File...".
On the file creation screen, select Header File and click "Next"
On the following screen, choose a name for your header file and click "Create"
The bridging header file is now created
The header file should look similar to the following:
#ifndef Swift_Bridging_Header_h
#define Swift_Bridging_Header_h
#endif
Next, you will need to link your header file to the bridging header setting. Navigate to Build Settings within Xcode
Type "bridging" into the search bar and double click the Objective-C Bridging Header setting to get an input box
Type the relative path to your project directory and the name of the bridging header file and then click enter to save the setting
