duplicate symbols for architecture i386 [closed]

Question

I am using GTL framework for using google GDrive. I copied all the files from the GTL.xcodeproject into my application after getting failed many times in importing that framework into my application. But still i am getting below mentioned error. I have searched all but found no duplicate files or anything. Please help here.

Answer 1

Make sure you check the "Compile Sources" in your "Build Phases" section as well. Sometimes they get doubled in there (but appear only once in the project file explorer)

Answer 2

Try to delete all the files/folders from your project location and also remove references from XCode project.

Then, copy library folder to project location and in XCode, click on "Add files ..." and choose the new added folder in project location.
