I found many questions on here asking for the same thing. I have tried all of them but I am still getting this error. I created everything from scratch again and was running well until I deleted the data from "DerivedData" folder and now this permissions alert error came back.I have been trying following things for a week now:I have tried copying this project to a new folder. Didn't work.I changed every permission to my folder structure to be read & write to every user.Product -> Clean.Renaming the app.Compiler for C, C++, Objective-C is "Default compiler Apple LLVM 8.0)Build Settings > Architectures -> to Standard ArchitecturesReplaced Info.plist from a newly created project.Xcode version 8.1.I see that one of the similar questions were tagged as a duplicate. But I am really stuck here for a week. I have tried everything from this answer in the StackOverflow.And a lot of others that I found online.I would really appreciate any help on this. I couldn't finish my project because of just this permission issue.Thank you in advance!
