I uploaded my project on Google Drive, now it doesn't compile anymore

Hello to all, I hope you are well. I code on a virtual machine (remote use) and I had to put the project in my Google Drive. I downloaded it earlier and I try to compile the file but it shows me these two errors. I read this solution on stack overflow( https://stackoverflow.com/questions/41545658/could-not-determine-generated-file-paths-for-coredata-code-generation ) but I really don't understand it, I'm a beginner, can someone help me please? and I don't know why it tells me that it can't find 'Google Mobile Ads' when I installed it earlier. Please I need help urgently. The application should be ready this Friday.
