I got one error when I run my app. The error is linker command failed with exit code 1 (use -v to see invocation).
The error shows me that there are 2 duplicate symbols for architecture x86_64.
I could not find a solution. How can I fix this?
Please help me for this issue.
It looks to me as if you have both 2.0 and 3.0 AFNetworking in your project. I don't see AFURLConnectionOperation in the 3.0 source but your link log shows it in conflict with AFURLRequestSerialization, which is in 3.0.
In fact, the github migration guide says:
The following classes have been removed from AFNetworking 3.0:
AFURLConnectionOperation
AFHTTPRequestOperation
AFHTTPRequestOperationManager

ld: file not found: linker command failed with exit code 1

I KNOW what this error message
"Linker command failed with exit code 1 (use -v to see invocation"
means. I have duplicate symbols.
What I DON'T know is what "use - v to see invocation" means.
How do I actually use -v? In Terminal or where? Please someone, give me an example of its actual use.
Thanks for your help.
I found a way to get the error info: Control-click on the red error indicator (at left), then select Show Error Log, which gives the complete information.
(Meanwhile the "Use -v" message remains useless.)
What I have done after 2 days of reading stack overflow:
Keywords to problem:
"Apple-Mach-O Linker Error",
"libGGLCore.a(Clientanalytics.pb.o,Icore.pb.o,Jspb.pb.o,LogsAnnotations.pb.o

I Don't use pod. Manually Download files from Github
So I am stuck. How do I solve the problem(s) displayed in the image below:
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Did you download all the dependent pods? To make GCM work, you need Google, GoogleCloudMessaging, GGLInstanceID, GoogleInterchangeUtilities, GoogleIPhoneUtilities, GoogleNetworkingUtilities, GoogleSymbolUtilities, and GoogleUtilities.
There could be various errors in your code as per your description. Some of the possibilities are:
1. Please read this
2. Importing QuartzCore in the project might fix the issue too.
3. Cleaning the project and restarting might help you too.
4. Changing the architecture of the project from armv6 to armv7 or arm64 could help too.
5. Moving the linked library of GCM to another folder also causes this issue. Please check it out too.

Select your Project and choose your "Moip Store Test" - Target, go to "General" and set your Application as Host Application.
I have problems with Swift Compiler:
I created new project for iOs on latest Xcode 6 and tried to build - recieved 2 errors with ViewController.swift and AppDelegate.swift.
<unknown>:0: error: unable to execute command: Segmentation fault: 11
<unknown>:0: error: swift frontend command failed due to signal (use -v to see invocation)
<unknown>:0: error: unable to execute command: Bus error: 10
<unknown>:0: error: swift frontend command failed due to signal (use -v to see invocation)
I can post a full logs if if it is necessary.
What should i do? Thanks.
I have faced a similar issue while working with a swift project. I found this on Apple Support Website. It says that this type of error occurs when you tried to access an non-existent/inaccessible memory address. To solve the issue you can quit unused applications or even restart the mac which will probably help you.
