Undefined symbols for architecture i386 - All items from podfile

Question

I am getting the below error for Restkit, however reskit is added using cocoapods. I have tried a lot of solutions and can not seem to find the correct one. Does anyone know what I am doing wrong?

Error Message:

Edit: I am also receiving the following warnings which is the files that are missing.

d: warning: ld: warning: ld: warning: ignoring file /Users/ME/Library/Developer/Xcode/DerivedData/MYWORKSPACE-bceskqnbpsdarjfijbrjozdfciem/Build/Products/Debug-iphonesimulator/libPods-RewoIOSCore-ISO8601DateFormatterValueTransformer.a, file was built for archive which is not the architecture being linked (i386):

If things have ended up messy, I would try doing a fresh install of your CocoaPods dependencies, using the following steps:

• Check that your Podfile refers correctly to your app's target.
• Open the Build Phases tab of the target and find "Link Binary with Libraries". Remove CocoaPods.

• Delete the .workspace file
• Delete the Pods/ directory
• Run pod install again.
