I have downloaded an App that I need to work on from a colleague, but whenever I try to run it to test on Xcode, the build fails with 53 errors, all pertaining to the "Apple Mach-O Linker Error, X referenced from:" type.
I'm completely new to iOS development and Xcode as an IDE, so maybe I'm missing something incredibly basic.
For more info, I am also working with the Neoflix template.
What can I do to fix these issues?
