Exactly what it says on the title. I've downloaded the STTwitter API several times making sure nothing went wrong with my download. I ran my project before importing the library and it runs fine.
I know there is nothing wrong with the STTwitter library because I used it in several projects, but it won't let me create another project with the import.

Please, if anyone knows something about importing the library, let me know :)
This pull request may fix the issue: https://github.com/nst/STTwitter/pull/189
Please checkout the very latest version from head.

All,
I am having trouble compiling an old project I saved to dropbox, and then downloaded to my computer after a hard drive wipe. I believe I have installed all appropriate frameworks again, but am met with the following error:

Your project contains duplicate symbols which means you're trying to compile two identical files which contain the implementation for the same class. Check your project files and eliminate any duplicate .m files (like CustomCell and ViewController)
Maybe _IS_ALREADY_LOGIN, _TRUE_CHECK etc is defined more than once in CustomCell.h/m and ViewController.h/m?

I can't understand what's wrong with my app. I searched on the web to try to understand what's wrong and I found the following solution:
Check if I import .h files and not .m files --> In my app all ok
Check the correct Framework --> In my app I use only the default Framework, so no problem
Check the Library search path --> In my app there are no problem about this
So what's the problem? Can you help me to fix it?
I just started using cocoapods and can't figure out what the heck is going on. I've installed a library for a ViewController and keep getting the following errors:

I've tried removing the Library path in build settings, I've tried reinstalling a pod install and pretty much every other option recommended on the web.
I have no idea where to go from here...
Hope you guys know how to fix this one. I probably just need to add a framework to the link binary but I can't really find which one to add.

You aren't missing a lib but you have 2 C functions called Pressit, Push and SavedData that conflict!
The duplicated symbols are in FirstViewController & SecondViewController.
Solution:
Don't implement the same functions twice:
If they are equal, move them to a third file and include them only.
If they differ, rename them.
I guess, you might have implemented FirstViewController three times in your project.
Search for FirstViewController throughout out the project and keep only one FirstViewController for project.
