Sharapie tool does not generate C# code properly.

Hi Folks,

I want to print receipts using EPSON TM-T88V thermal POS printer through mobile on Android and iOS platform.
For Android, I downloaded EPSON SDK from here.
For iOS, I downloaded it from here.

Epson SDK for android contains two .jar files named ePOS2.jar and ePOSEasySelect.jar and two libraries with extension .so named libepos2.so and libeposeasyselect.so which were referenced to Xamarin.Android project successfully, printing receipts on android went well.

For iOS, I refereed this walk-through on Xamarin documentation.

I used the following command to generate the c# files where my header and binary files were located:

sharpie bind --output=ePOS --namespace=ePOS --sdk=iphoneos12.0 *.h -scope ePOS

The generated files have too many syntax errors, which I don't know how to resolve at the moment. Below is the Structs.cs file with errors like "Identifier expected".

public struct
{
    [FieldOffset(0)]
    public long double __f;

    [FieldOffset(0)]
    public ulong __u;
}

Kindly help, and suggest whether I'm going in right direction.
