Looks like you should add "CoreMotion.framework" and "CoreLocation.framework" to the "Linked Frameworks and Libraries" section of your project properties.

I have issue pls tell me anyone

I created one custom framework for social login it's working as debug mode
but whenever I build framework for release mode it gives error like

Undefined symbols for architecture x86_64:
"OBJC_CLASS$_Social", referenced from:
objc-class-ref in ViewController.o
objc-class-ref in DetailViewController.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

I do not understand what is happaning on release mode

I write singleton class of Social
and it has one method as

+(instancetype)methodSocial { }

Hi @khaire1111

Your problem doesn't look like related to g3m. Am I right?

Hi, at first thank you for answer me. I have linked again the coreMotion and CoreLocation and now have a new error
libG3MiOSSDK.a(Downloader_iOS_Handler.o)' does not contain bitcode. You must rebuild it with bitcode enabled (Xcode setting ENABLE_BITCODE), obtain an updated library from the vendor, or disable bitcode for this target. for architecture arm64
If I do that I have again this
Undefined symbols for architecture arm64: "std::_List_node_base::unhook()", referenced from: std::list<FrameTask*, std::allocator<FrameTask*> >::_M_erase(std::_List_iterator<FrameTask*>) in libG3MiOSSDK.a(FrameTasksExecutor.o) "std::_Rb_tree_increment(std::_Rb_tree_node_base const*)", referenced from: std::_Rb_tree_const_iterator<std::pair<std::string const, JSONBaseObject*> >::operator++(int) in libG3MiOSSDK.a(JSONObject.o)
I have 62 issues but only copied the firsts as example.
I created a new project with a menu and some views, I have cocoa too. I don't know if this can help you.

Can anyone help me?
