iOS - GoogleSignIn sdk integration in Objective-C project using pod is resulting in link error

Question

After integration of GoogleSignIn sdk, i am getting the following link error -

Undefined symbols for architecture i386: "_OBJC_CLASS_$_GIDSignIn", referenced from: objc-class-ref in xxx.o objc-class-ref in xxx.o ld: symbol(s) not found for architecture i386 clang: error: linker command failed with exit code 1 (use -v to see invocation)

I tried the following setting changes but still the issue persists 1. framework search path, library search path = $(inherited) other linker flag = -ObjC 2. Added SafarServices.framework, security.framework, systemconfiguration.framework, addressbook.framework, libz.dylib 3. build active architecture only = false 4. valid architectures = (armv7, arm64, i386, x86_64)

The problem is the binary is getting created with i386, x86_64 architecture after checking with lipo -info command but still this linking coming.

Any help is really appreciated.

Answer 1

Try manual integration instead of CocoaPods. It's not difficult and can be more reliable for binary dependencies in my experience.

Add the SDK your Xcode project

1 Extract the SDK archive you downloaded and copy the following files to your Xcode project:

 GoogleSignIn.bundle GoogleSignIn.framework GoogleSignInDependencies.framework 

2 Add GoogleSignIn.bundle to your Xcode project's Copy Bundle Resources build phase.

Link dependent frameworks to your Xcode project

1 Link the following frameworks to your Xcode project:

 SafariServices.framework SystemConfiguration.framework 

2 Add the ObjC linker flag to the app target's build settings:

• Other Linker Flags: $(OTHER_LDFLAGS) -ObjC

This should get you at least far enough to build. Also try cleaning your DerivedData folder.
