MbientLab has an SDK for iOS that I want to integrate into Xamarin.iOS, however it's not working.
I did the following:
On a mac I've initialized MetaWear from CocoaPods using Objective Sharpie
sharpie pod init ios MetaWear
It downloaded all files needed for MetaWear correctly. Next I tried command:
sharpie pod bind
Which seemed to be working fine at first (both Bolts and FastCoding are build correctly) but at the end it fails:
Parsing 1 header files...

Because of this I tried binding the .h-file generated while building, like so:
sharpie bind build/Release-iphoneos/MetaWear/MetaWear.framework/Headers/MetaWear.h -sdk iphoneos
Which doesn't work either:
Parsing 1 header files... /Users/vans/Documents/MyMetaWearSDK/build/Release-iphoneos/MetaWear/MetaWear.framework/Headers/MetaWear.h:36:9: fatal error: 'MetaWear/MBLAccelerometer.h' file not found #import <MetaWear/MBLAccelerometer.h> ^ Binding... 1 error generated.

As a workaround I opened MetaWear.h (and the other header-files) and altered all import-statements from
#import <MetaWear/MBLFILENAME.h> to
#import "MBLFILENAME.h". After trying above Command again both ApiDefinitions.cs and StructsAndEnums.cs were generated. These cannot simply be copy-pasted into VS2017 (Xamarin.iOS Binding Library) because a lot of compilation errors occur.
The type or namespace name 'MBLCalibrationAccuracy' could not be found. Are you missing an assembly reference? The type or namespace name 'MBLBarometerBoschOversample' could not be found. Are you missing an assembly reference? ...
What am I doing wrong? How can the MetaWear-SDK be integrated into a Xamarin.iOS-project?
