I'm developing an application with XCode 4.1.1
I added the library from http://sudzc.com/ for consume web services.
When I compile the application, it gives this error:
Undefined symbols for architecture i386:
"_OBJC_CLASS_$_SDZInfo", referenced from:
objc-class-ref in SimpleTableViewAppDelegate.o
objc-class-ref in RootViewController.o
"_OBJC_CLASS_$_SoapFault", referenced from:
objc-class-ref in RootViewController.o
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)
The configuration of XCode is Build 2.4 and Deplo yment Target 5.1.
This solution does not working for me because SimpleTableViewAppDelegate.m and RootViewController.m are added "You can get this type of error if your class' .m file is not listed under the "Compile Sources" step of the "Build Phases" tab of your target. Normally Xcode does this for you, but sometimes it loses the plot and you need to add the .m file manually"
Thanks in advance for your help.
The error is saying that the missing files are the ones that contain SDZInfo and SoapFault. The two .m files you mention must already be in the project because they are listed as the places where those things are required.

I am working on a flutter project. My project includes tflite and amplify packages. it works fine with android but whenever I try to build it in Xcode I am getting this following errors:

Please help me with this. I have been stuck with this issue for more than a week now. Thank you.
I have added a snippet from Xcode which shows the current settings for Architectures. There are past suggestions to add arm64 as a Valid architectures. However, as you see there is no option for that. I added arm64 in excluded architectures as shown in the picture. It didn't work for me.
I am trying to update the DJI SDK of my app to the latest version (i.e. v4.10 for DJISDK/UXSDK and v1.5 for DJIWidget) in order for it to be compatible with Matrice 200 V2 series. I have come across an error which I was able to reproduce as well with the sample application from the DJI Mobile-UXSDK-iOS repo.
Basically when I try to archive the app it have this error showing up:

Before this version everything worked fine, so I guess it is a problem with the newest DJI SDK version.
I am using the ObjectiveC sample code, and the app works fine in debug mode running it on an iPad Pro.
In case anyone is running into this problem, it seems that the new DJI SDK is not compatible with armv7 architectures, so the solution here is to go to the XCode Build Settings tab of your project and remove armv7 under Valid Architectures as it was done by this commit on the DJI Mobile-SDK-iOS repo.
I'm trying to use the MWPhotoBrowser project in my project. I followed the whole installation process and was able to import the MWPhotoBrowser.h file. When I tried to build, I run into this error...
Undefined symbols for architecture x86_64:
"_OBJC_CLASS_$_MWPhotoBrowser", referenced from:
objc-class-ref in PhotoBrowserViewController.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Does anyone know how to resolve this?
Thanks
For anyone getting this issue...Please check if you correctly linked your project to the libMWPhotoBrowser.a file under Build Phases in your target settings !
When I deploy my app to my phone via xcode5 it works find, however when I try to deploy it to one of the simulators I get the following errors.
ld: warning: ignoring file /Users/benpearce/Downloads/MapKit.framework/MapKit, missing required architecture i386 in file /Users/benpearce/Downloads/MapKit.framework/MapKit (2 slices)

Can anyone see what's going on?
The MapKit framework is missing a binary for the Simulator which is i386. The Simulator is a Mac application and needs a code resource compiled for the i386 Intel processor. Where did you get MapKit?
If this is Apple's MapKit you should just be including the framework provided with Xcode. It is added in Xcode by selecting the Project, Build Phases, Link Binaries with Libraries, +, select MapKit.framework.
Also the framework in in your Downloads directory, why?
I use zxing lib in my OS X application. I've included zxing-objc to my project and simply copy-pasted code from zxing demo (zxing-root/objc/examples/demo) to the separate ViewController class. When trying to compile project, I get the following linker errors:

I've carefully checked all code and compared my project properties (including c++ compiler options) to demo project properties, and everything is done right.
You need to add the necessary frameworks to your app target. You can look in the sample app for an example. Select the target in Xcode, select Build Phases, and open the Link With Libraries entry. You'll see that it includes both QuartzCore and zxing-objc-framework. It sounds like you don't have those in your project.
