I am getting below linker errors upon build in an Xamrain Forms iOS project. I have tried from both a Visual Studio for Mac and from Visual Studio Windows paired with a Mac.
I have referenced as many Xamarin.Firebase.iOS.* assemblies as I can see as relevant but no luck.
What am I doing wrong?
Thanks
Regards

EDIT (22/06-21): I went thru all my nugets one by one and found that the extra mtouch args. comes from the Xamarin.Firebase.iOS nugets. Someone over there has made the lib. so that it append some global mtouch flags. (the current stable version appends "-ObjC -lc++ -lsqlite3 -lz")
Since it dont seem to help to open an issue over there i must somehow make my lib. work with those flags. great...
I have a weird problem with building a ios forms app.
We have made a dll of a native library (openCV2) with some functions we need.
we have made a PoC that builds and runs just fine, but when we take it to the "real" app it cant build.
right before the build fails i see in the log:
/Library/Frameworks/Xamarin.iOS.framework/Versions/Current/bin/mtouch #/Users/xxx/Library/Caches/Xamarin/mtbs/builds/xxx.iOS/xxxx/obj/iPhone/Debug/device-builds/iphone11.2-14.6/response-file.rsp -v -v -v -v --gcc_flags=-ObjC
while on the PoC app the same line is:
/Library/Frameworks/Xamarin.iOS.framework/Versions/Current/bin/mtouch #/Users/xxx/Library/Caches/Xamarin/mtbs/builds/xxx.iOS/xxxx/obj/iPhone/Debug/device-builds/iphone11.2-14.6/response-file.rsp
i know the "-v -v -v -v" is from my additional mtouch args. but no where (that i can find) is the gcc_flags set and i cant find a way to remove it.
what i have tried with no luck:
linking Foundation framework in the additional mtouch args. linking
Foundation framework in the LinkWithAttribues.cs file in the binding
project none, sdk-only and all linking. looked at diffrenses in the
project files made all the changes i can think of in the LinkWith
file eg. linker flags, smart linking c++ and the like. tried with and
w/o this linker flag L/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/swift/iphonesimulator/ -L/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/swift/iphoneos -Wl,-rpath -Wl,#executable_path/Frameworks
made sure the code in the implementation and PoC is 100% the same
made the iOS build options 100% the same in project and PoC
installed the xamarin.swift nuget
tried both 4.8 and 5.0 xamarin forms
im running
vs for mac 8.10 (for binding project)
vs2019 16.10.1 (for app building)
xamarin.ios 14.19 on both
does anyone have a idea on what is going wrong here?
Im at the end of my rope, any help or ideas on where to look would be greatly appricieted.
here is the complete "failing" build log:

Can you please check changing the Linker Behavior to "Link Framework SDKs only" :
The application is ready for Xamarin IOS.
Yesterday there was no problem. I did visual studio update for hot restart to 16.7.3.
Today when I turn it on, I am remote to the mac, but when I say build, I get linking failed errors like the following, about 33.
I haven't installed any nuget packages etc.
It took me a day to undo the last changes I made.
It builds when not connected to the Mac but when I connect to the mac I get these errors anyway.
I can't figure it out. Can you help me?
This is the project output while building:
