at first you need to understand that. https://docs.unity3d.com/Manual/IL2CPP-BytecodeStripping.html

to prevent stripping.

• using [Preserve] attribute
• or using link.xml

for example.

Person.cs with [Preserve] attribute

namespace HelloWorld.Nice.To.Meet
{
    [Preserve]
    public class Person  {

    [PrimaryKey, AutoIncrement]
    public int Id { get; set; }
    public string Name { get; set; }
    }
}

link.xml under directory Assets/ or Assets/'s subdirectory

<linker>
    <assembly fullname="HelloWorld.Nice.To.Meet" preserve="all"/>
</linker>%

I use SQLite4Unity3d for some time and I've never entered

using [Preserve] attribute or using link.xml

is it necessary to do it for encryption of SqlCipher4Unity3D?

thanks

unity's IL2CPP build not only stripping unused code. sometime stripping class name. for example

db.sqlite

Hello

id	value
1	val

Hello.cs

class Hello
{
  int id { get; set;}
}

you can't find name by Hello so It will be failed without prevent stripping db.Get<Hello>(x => x.id == 1);

but this also happens with SQLite4Unity3d?

[netpyoung]

I think also happen in SQLite4Unity3D if ios building with.

[cabanel]

I've been using SQLite4Unity3d for years to develop apps for ios and I've never used

[Preserve] attribute or link.xml

um.. I don't know exactly. but In my case It needed. If that's work what you said, It also good.
