When I tried to use Parse SDK with swift, I just noticed how did I use Parse SDK with swift.
First, I tried to code like Objective-C. Of course, it didn’t work and it only displayed some error, “You can’t do that because you have to import Parse SDK.” After that I googled and did try & error. Finally, I could use Parse SDK with swift. So I’m gonna show you how to use Objective-C library with Swift.

Step1. Create a header file
[Create New file]-[Header file] At that time, you have to name “ProjectName-Bridging-Header.h.” It’s a rule.
If your project name is “ParseTest”, you have to name “ParseTest-Bridging-Header.h”.

Step2. Add Parse header file path
If you finish step1 well, Xcode will create the file like below
