I am trying to run the sample project of zoom api.

[https://github.com/zoom/zoom-sdk-ios](https://github.com/zoom/zoom-sdk-ios)

I double checked all the instructions and looked for everywhere about “Apple mach-O linker error.” All the results were about linking the frameworks. I have all the frameworks included in Link Binary With Libraries. Then above all the errors I noticed this warning which says about ignoring the framework because of missing architecture. Here is the list of warning and errors.

Undefined symbols for architecture arm64:  
“\_OBJC\_CLASS\_$\_MobileRTC”, referenced from:  
objc-class-ref in libRNMobileRTC.a(RNMobileRTC.o)  
“\_kMeetingParam\_IsAppShare”, referenced from:

I doubt that you used wrong iOS SDK framework, please have a verify with this release package:&nbsp;[https://github.com/zoom/zoom-sdk-ios/releases](https://github.com/zoom/zoom-sdk-ios/releases), which was mentioned in github.

Thanks!
