I am building a Unity project to my device on Xcode. I started using cocapods to fix another issue.
Now I am getting this error:
The armv7 architecture is deprecated. You should update your ARCHS build setting to remove the armv7 architecture.
What does this error mean and how to get rid of it?

Having an issue building for iOS. Getting "linking for arm (arm64) failed with Undefined symbols for architecture arm64: "____libinfoptr_mergZXing", referenced from: -u command line option
Any ideas what might be wrong? Let me know if you need additional details
When you get linking errors with iOS externals it means it either hasn't been compiled for the SDK or architecture you are building against. In this case it's telling you it hasn't been compiled against arm64. The good news it that there are universal binary builds (armv7 arm64) available for download from mergExt.com for up to iOS 8.2. iOS 8.3 builds will be coming ASAP.
I've recently updated xcode to the last version. So now my simulator have 8.2 ios version. My cocos2d-x projects are still working on devices (tested on ipad2 and iphone5s), but I can't compile them for simulator. I'm getting huge number of linker errors:
Undefined symbols for architecture x86_64:
"_AVAudioSessionCategoryAmbient", referenced from:
-[CDAudioManager setMode:] in libcocos2d iOS.a(CDAudioManager.o)
-[CDAudioManager applicationWillResignActive] in libcocos2d iOS.a(CDAudioManager.o)
...
few hundred lines more
...
ld: symbol(s) not found for architecture x86_64 clang: error: linker command failed
with exit code 1 (use -v to see invocation)
Showing first 200 notices
only Showing first 200 errors only
Generally there are errors of all frameworks I use as well as cocos2d-x library itself. Before getting there most frameworks was highlighted red, but I fixed that making a symlink to:
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs
using this:
sudo ln -s iPhoneOS.sdk iPhoneOS8.1.sdk
I'm of course using cocos2d-x 3.4.
edit:
After migrating to v. 3.5, setting valid architectures to: armv7, armv7s, i386, x86_64, setting build active architecture only to no (in both main and cocos2d_libs project) with various settings variations now I'm getting:
Undefined symbols for architecture i386:
And other's the same. Doesn't work on any simulator. I even downloaded 8.1 simulators and it doesn't work there too. This is some stupid linker error and I can't figure it out.
I've also noticed that fresh project builds fine. In my project I also have few objC classes (for other stuff like admob), which are using ARC. So I had to add "-fobjc-arc" in few places in build phases->compile sources. Problem is it's only simulator-related problem and appeared when I've updated ios sdk from 8.1 to 8.2.

I have an issue while Running my unity project on xcode. I get over 78 Apple Mach-O Linker Errors. I have implemented a bunch of Plugins as well. However I have included all the frameworks that are required for those plugins to run.Now I am not sure why I keep getting these issues. I have attached an image of some of the Mach-o linking errors im getting. Im trying to deploy the build for iPhone 6 running 8.2 and it Xcode 6.2.

So I've had some headaches today trying to solve this one. I have SQLCipher integrated into an iOS application and before I go further, here are my architecture build settings:
As I understand it, this should only build for an armv7s device (such as a iPhone 5), and when trying to run on a armv7 device I quite rightly get this error:
So I try changing the project's build architecture to Standard (armv7s, armv7) and build. This still runs as expected on the armv7s device, but on a armv7 device I get these linking errors:
So naturally I check out the build settings for the library throwing these errors, and they both have armv7 and armv7s in the valid architecture setting, so does anyone know why am I getting those build errors on the armv7 device? I am missing something?
Here are the build settings for the libraries I'm using (openssl-xcode and sqlcipher):
To fix this read the comments above from Stephen and then I did a project clean and rebuilt it.
I'm using xcode 4.5 My Base SDK is 6.0 and my deployment target is 5.1. When I try to build for release or profiling I get this little gem of an error.
ld: file is universal (4 slices) but does not contain a(n) armv7s slice: /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.1.sdk/usr/lib/crt1.3.1.o for architecture armv7s
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Now....
I have seen this message posted on stackoverflow but Im still none the wiser.
What exactly is this crt1.2.1.o thats causing all the fuss?
Can I modify it somehow to kill my error?
And finally it has been suggested that I simply set build for active architectures only. What are the implications of doing this?
Thanks
The crt1.3.1.o file contains the startup code for the C runtime library. This initializes the runtime, calls global initializers and finally calls the main function.
Something must be amiss with your project settings. You are compiling for armv7s as well, but the libraries are being linked from the iOS 5.1 SDK which doesn't support the armv7s architecture yet.
I had this same issue, I removed armv7s from valid architectures in build settings and left only armv7, after that I could archive my project
