You need to link against the SystemConfiguration framework. Select your project in Xcode's project navigator, select your app target, and select the Build Phases tab. Under Link Binary With Libraries, click on the "+" button and choose SystemConfiguration.framework.

There may be other framework dependencies that you need to add in the same way, but adding SystemConfiguration is what fixed the same errors for me.

ETA: I jumped right to the errors and didn't see the ld warning at the top of the paste. If you're already linking to SystemConfiguration, maybe try removing and re-adding it, and if all else fails, update Xcode. The most recent release definitely has the right architecture, so it sounds to me like either your project is looking in the wrong place or something's wrong with the framework itself.

You, my friend, rock. This took 30 seconds and instantly solved it for me. Thanks. – Winterkill

Thanks for this! You just saved me from what could have been a long afternoon :) – Elevated

Worked for me as well. I think this is the right answer. – Pahari

Just realized I'd never actually accepted this as the correct answer. – Tarrant

Sigh. It's 2016. WHY doesn't Xcode help us to get around issues like this, rather than squirting out vague error messages ?! I noticed yesterday that the apple.com/feedback website lets you give feedback on all Apple hardware and software, EXCEPT Xcode. Funny, that... Anyway, thank you - this perfectly fixed my problem !! – Antares

@Siobhan the solution that you point here is deserving more than a plus I'd give 10+ really change my project from uncompilable to compilable. Xcod – Bascom

Happened to me when I was including a framework that was built using Carthage and it's deployment target has been set to iOS 11 but I was building for iOS 9. Therefore the 32-bit architectures (armv7, i386) were missing. I have changed the deployment target for that framework to iOS 9 and that fixed my problem.

Thanks this helped alot! Same issue for me. – Need

This problem is related to the XCode messing up debugging, profile and final release files, when trying to get a shorter build time reusing old files.

That's why an architecture is missing (and it's probably the opposite of what you've already used), because XCode is trying to reuse some previous files that it built for a single architecture.

Clean your project in XCode (⇧ + ⌘ + K) and try to clean all other third-party libraries as well. After that, try to rebuild your app directly in the desired release mode. This worked 100% times without the need to restart XCode.

XCode stinks, what else could I say??

Answer 5

Add army in your project ( Path => Project tittle(select Xcode blue color reject title) -> Build Setting -> ARCHS) in this ARCHS if you don't have armv7 than add it...

Hope,this will help you..

I had the same issue for the framework Twilio Chat client. And when I went into carthage folder and inside it open the Info.plist file for Twilio Chat client framework the minimum deployment target was set to 11.0 but I was developing application for 10.0 so it was missing those architectures.

How I resolved: I downgraded my Twilio Chat Client framework to earlier versions where deployment target was set to 9.0 and boom it works.
