Undefined symbols for architecture arm64

[amishra]

Hi,

I am using Xcode 10.1and GStreamer iOS latest version. I created a project
by using "GStreamer single view template". However, I got error messages
when I tried to build the app. 
The error messages are as below. Please help me figure out how to fix this
problem Thanks.
