Seems like you're importing the same (virtually) library - one ARC, one NON ARC. Remove one of them

Struggling with RestKit & AWSSDKiOSv2 and linker flags

I'm trying to use RestKit and AWSSDKiOSv2 together on an iPhone project.
RestKit wants me to have these linker flags: -ObjC -all_load but the AWS SDK would rather I didn't. Are these two libraries incompatible with one another? I've looked around but I haven't seen much on both of them together which seems surprising.
Here is the linker error I get when I try to keep them:

Found this link:
https://stackoverflow.com/a/5095793/1082660
and updated my linker flags to: -force_load $(BUILT_PRODUCTS_DIR)/libRestKit.a
and all seems to be working.
Note, I also double checked my imports. I originally had the commented out lines below but changed them to the uncommented lines. That may have been a confounding factor.
//#import "AWSiOSSDKv2/AWSCore.h"
//#import "AWSiOSSDKv2/AWSS3.h"
#import <AWSiOSSDKv2/AWSCore.h>
#import <AWSiOSSDKv2/AWSS3.h>

I don't understand why reason. Everything is normal until I add 'Edit View Controller' to my app. I have tried to delete 'Edit View Controller'. However it does not work. Can you please help me if you know solution for this issue? Thanks
You have something called a AddTransactionViewController. In it, you're including storage for your EditViewController. This may be because you're including a .m file instead of a .h. Or, it might be because of something in EditViewController.h that shouldn't be there.
Check your include/import lines in AddTransactionViewController.m and .h.

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.

Duplicate Symbols for Architecture in XCode with Qt5.1.0

This is the output from XCode when I try to compile. I have thoroughly checked my header files to verify that I am not including something twice. Does anybody see what else could possibly cause this issue? I've even deleted the project and regenerated it. I don't know what I did that could make this happen. Thanks in advance!
