I'm not quite sure how to troubleshoot this and was hoping for some insights. I've got a Xamarin Forms solution that uses an iOS binding library I created from a 3rd party. I got new files and was able to bind it and create a dll. The only thing different was this time I had to use Xcode 9.4.1. When I brought the dll back into my xamarin forms solution I get the errors below by running against an iOS simulator with the following Additional mtouch arguments
--registrar:static --gcc_flags -stdlib=libc++ -v -v -v -v
In the iOS binding library my native reference libMyChart.a has the following settings:
Force Load: True
Frameworks: WebKit HealthKit CoreGraphics Foundation UIKit CoreLocation MediaPlayer SystemConfiguration MobileCoreServices QuartzCore EventKitUI EventKit OpenGLES AudioToolbox CoreVideo CoreMedia AVFoundation Security CoreText CFNetwork
Linker Flags: -ObjC -lstdc++ -lxml2
Smart Link: True
