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.

```
ld: warning: ignoring file ../lib/mobileRTC.framework/mobileRTC, missing required architecture x86_64 in file ../lib/mobileRTC.framework/mobileRTC (2 slices)
    Undefined symbols for architecture x86_64:

    ld: symbol(s) not found for architecture x86_64
    clang: error: linker command failed with exit code 1 (use -v to see invocation)

```

Why there is no&nbsp;build of the library for x86\_64 architecture? I can’t use a device, need to run it on the simulator at the moment.&nbsp;

Please download the following build: [https://github.com/zoom/zoom-sdk-ios/releases](https://github.com/zoom/zoom-sdk-ios/releases), this build is for both simulator and device. If you downloaded the build directly from github, it is a device only framework, cannot support simulator.&nbsp;

BTW, we have comment this in Github.

_This version is the device-only framework, you can download our Mobile RTC™ Stack with device and emulator framework from the&nbsp;[releases](https://github.com/zoom/zoom-sdk-ios/releases)&nbsp;page as well._
