I have done a lot of research but i didn't find any helpful thing.
I have following problem.
I am trying to make an app for school. till now it is working fine on simulator and on my iPhone 4 and on my iPad 3. i have imported the 'RestKit' project to use it for the connection with my restful web service. (imported it with cocoa pods)
now i wanted to test it on the simulator on the 64-bit device (iPhone 5S)
but since i have added an open source project (ZBarSDK) for an QR-Code Reader i am getting this error.
