I am trying to rebuild my xamarin.iOS project in release mode and i am getting following Errors:

1. linker command failed with exit code 1 (use -v to see invocation).

2. error MT5209: Error: warning: ignoring file /Users/admin/Desktop/1DMAPP/MobileApp/MobileApp/MobileApp.iOS/obj/iPhone/Release/mtouch-cache/BEMCheckBox.framework/BEMCheckBox, missing required architecture armv7s in file /Users/admin/Desktop/1DMAPP/MobileApp/MobileApp/MobileApp.iOS/obj/iPhone/Release/mtouch-cache/BEMCheckBox.framework/BEMCheckBox (4 slices) (MobileApp.iOS) Native linking

I am using the latest and stable version of packages.

My Link Behavior is "Don't Link"

My project supports all architectures

I want to build and release my iOS app. Native linking error is not allowing me to do this.
