Having trouble with FireBase

I am currently trying to connect Firebase with my app and while in the Terminal I’m not able to navigate to the folder that’s on my desktop. I’ve successfully installed cocoaPods (I think) and I just want to get past this part. Did I give my project a name that Terminal can’t recognize? If so, Can I rename it without messing anything up?

$DDD seems like a very weird name, try naming it without the special character
