Using Xcode to build and clean up my Buildbox project. Seemed to be running fine on my phone. Now it won't build properly. I can't figure out which library is needed to download with the words, "-lbullet". I was told by a friend to re-upload the file and the error will disappear, but it didn't fix it. I'm using Xcode 11.6. I know other similar problems to this were solved by removing and re-downloading the library but I don't know which one it is. Any help would be greatly appreciated. Thank you, Adam
