I am trying to upload an app that was originally developed in obj-c with swift.
ERROR ITMS-90037 error while uploading identifier.
I also checked to see if there is a special character in Info.plist, but I did not enter it.
Is there any other way?

It's not about what chars you may have entered, it's about how that file itself was created/edited.
Did you create or at any time manually edit that Info.plist file, outside of Xcode? If so, what did you use for a text editor?
Did it originate with that project, and was the project created from an Xcode template?
