SinchService integration using Cocoapods failing
<p>I'm new to Sinch service, currently I'm trying to use 'SinchService' along with 'SinchRTC' via Cocoapods but Xcode is giving me this error:</p>

<p><strong><em>Undefined symbols for architecture x86_64:<br/>

<p>When I remove 'SinchService' from my Podfile no error is throw by Xcode. Help with this issue would be appreciate.</p>

<p>My podfile:
