-#ifndef slds_bridging_header_h
-#define slds_bridging_header_h
-
-#import <DesignSystem/SalesforceDesignSystem.h>
-
-#endif
+To use the SLDS library in Swift, import the library:
 
 ```
-  
-1. Create `slds-bridging-header.h`.
-2. In your build settings find the “Swift Compiler – General” section.
-3. Next to “Objective-C Bridging Header” add the header file (e.g. `slds-bridging-header.h`).
