Undefined symbol errors on Archive

[PachydermSoftware]

• DJI iOS SDK version 4.10
• iOS system version iOS 12.2
• iOS device type iPhone X
• Xcode version 10.2.1

When I try to archive the sample app I get a bunch of Undefined symbol errors. For example:

:-1: Undefined symbol: _DJILightbridgeLinkParamBandwidthAllocationForLBVideoInputPort
:-1: Undefined symbol: _DJILightbridgeLinkParamBandwidthAllocationForHDMIVideoInputPort
:-1: Undefined symbol: _OBJC_CLASS_$_DJIAirLinkKey
:-1: Undefined symbol: _OBJC_CLASS_$_DJIGimbalAttitudeAction

... (over 90 of these)

Steps to reproduce: Build and run the app in debug mode and all is well. Choose Product->Archive and the errors appear.

I realize I don't need to archive the sample app but I am also running into this issue with my app so this was the easiest way to repeat and explain the issue.
