Apple Mach-O Linker Error in XCode, after update to IOS 7.1 and XCode 5.1

This is weird problem, I recently updated my iPhone to IOS 7.1 (I wish I waited), because of that Xcode said it too needed to be updated. Did so, but now I'm getting Mach-O linker errors. Reading the description, it said that there was an ignored file the DropboxSDK (from the DropboxSDK.framworks) claiming that it is missing a required architecture arm64 in the file. This is a new one for me, I'm still very new to objective-c programming and XCode so any help would be welcome.

After searching for awhile, it apparently for me was arm64 in my valid architectures. After I removed that the errors went away.

Try this webanswer.

I have gotten the Mach-O error before when adding Crashlytics to a project. It seems to be an issue with the framework being misconfigured. But I could be wrong.

Thanks Patrick! I tried it but it didn't work for my case. Hi Allan, I just updated my iPhone to 7.1 too. Now I'm having the same issue - " Mach-O Linker Error". I will keep looking for solutions, and try different approaches. keep you posted if i find anything useful. Did you use PhoneGap or similar software? Could that be the causes?

I figured it out - you have to set the version of the app to the version that is on the device.

I ran into this issue and needed to double check the frameworks that I imported matched the ones in the video. I noticed that the current parse documentation they say to import libz.dylib however in the video they import the 1.1.3 file.
