In Swift

@import frameworkname

If your using cocoa pods try to make sure you have use_frameworks! in your cocoa pods pod file, otherwise the Swift Framework wont work. Also look at this for any other issues that may pop up: link

For making the bridging header visible to your compiler you need a little setup

1. Go to your Project Build Settings
2. Search for bridging header
3. Add the path to your .h file (usually ProjectName/ProjectName-Swift.h)
