I can not upload my app on Apple Store because of Xamarin.google.ios.Signin Nuget

[Luismimultimedia]

Hello,

Right now im facing a problem with the new politics of Apple Store with the UIWebView that the library Xamarin.google.ios.Signin i using, i can not upload my app into Apple Store because it use the deprecated UIWebView, the version that im using is 4.4.0.

i noticed that the problem was the library because i used the grep command in my .ipa to know what was happening, i try to update Xamarin.google.ios.Signin in to the lastest but when i try compile my app show me the next error:

/Users/alejandro/Desktop/Ventazer/App/02_CodigoFuente/Ventazer.iOS/MTOUCH: Error MT2002: Failed to resolve "Google.SignIn.ISignInUIDelegate" reference from "Google.SignIn, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" (MT2002) (Ventazer.iOS)

So i tryed to desinstall the nuget but when i clean my project and build it, it show me 3 new errors that are:

/Users/alejandro/Desktop/Ventazer/App/02_CodigoFuente/Ventazer.iOS/error MT5209: Error: file not found: /Users/alejandro/Desktop/Ventazer/App/02_CodigoFuente/Ventazer.iOS/obj/iPhoneSimulator/Debug/device-builds/iphone 11-13.3/mtouch-cache/GoogleSignIn (Ventazer.iOS) Native linking

/Users/alejandro/Desktop/Ventazer/App/02_CodigoFuente/Ventazer.iOS/clang: Error: linker command failed with exit code 1 (use -v to see invocation) (Ventazer.iOS)

/Users/alejandro/Desktop/Ventazer/App/02_CodigoFuente/Ventazer.iOS/MTOUCH: Error MT5201: Native linking failed. Please review the build log and the user flags provided to gcc: -ObjC -lc++ -lsqlite3 -lz -ObjC -ObjC -ObjC -lc++ -lz -ObjC -lc++ -lsqlite3 -lz (MT5201) (Ventazer.iOS)

i really dont know what to do, because if i update it, it doesnt work and if i desinstall it still not working, i would be so glad if someone can help me!

@Luismimultimedia I had the same problem
Apple does not accept because that version of Xamarin.google.ios.Signin has UIWEBVIEW deprecated
I Updated Xamarin.google.ios.Signin to latest version 5.0.2.1 and xamarin.google.ios.core too 3.1.0.4 when I did that I got the following error
/Users/alejandro/Desktop/Ventazer/App/02_CodigoFuente/Ventazer.iOS/MTOUCH: Error MT5201: Native linking failed. Please review the build log and the user flags provided to gcc: -ObjC -lc++ -lsqlite3 -lz -ObjC -ObjC -ObjC -lc++ -lz -ObjC -lc++ -lsqlite3 -lz (MT5201) (Ventazer.iOS)
then I tried to add Mtouch argument that recomend me but does not work
then I Update all my firebase packages to latest version works for me(compile) and apple accept my release on Testfligth

but my google sigin implementation crash with this line SignIn.SharedInstance.SignInUser();
:(
this is the exception
Unhandled managed exception: Objective-C exception thrown. Name: NSInvalidArgumentException Reason: presentingViewController must be set.

@stanleywailers Thank you for your reply, unfortunately i still facing the issue, i try to do what you did but i didnt get good results.
im working with a macbook pro 2013 and has Catalina 10.15.14, XCode 11.3.1 so at the moment i cant update xcode to the last version, i have read that updating xcode and other stuff could helps the library.
My characteristics of the visual studio are:

• Visual Studio Community 2019 for Mac Version 8.5.6 (build 11)
• Xamarin.Mac Version: 6.16.0.13
• Xamarin.iOS Version: 13.14.1.24
  I really dont know what to do :( because im stuck with this, i cant uninstall the nuget because it breaks my project and if i update it cant resolve Google.SignIn.ISignInUIDelegate.
  i hope fix this issue soon.
