My unity File Struct:
\Plugins\iOS\xatlas.cpp
\Plugins\iOS\xatlas.h
\Plugins\iOS\xatlas_c.h

edit xatlas.cs:
[DllImport ("xatlasLib", CallingConvention=CallingConvention.Cdecl)]
to
[DllImport ("__Internal", CallingConvention=CallingConvention.Cdecl)]

than compile unity project in xcode,print 12 errors blow:

try compile xatlas.cpp with two .h files to ios static library xatlasLib.a ,and unity call .a file.compile unity project show same 12 errors too.

can you help me slove this problem? thanks very much.

Random crash on some meshs.
In some cases,crush on program generated mesh.(generated by arkit).
In this exampleMesh, xatlas crash on random loop.
Is this problem cause by single chart? or angything?
ExampleMesh.zip

public class TestAtlas : MonoBehaviour
{
    public Mesh targetMesh;
    Mesh meshCopy;
    uint count;

    void Start()
    {
        meshCopy = Instantiate(targetMesh);
    }

    void Update()
    {
        if (!xatlas.Unwrap(targetMesh, 0))
            Debug.LogError("error");
        count++;

        Debug.Log(count + "success");
    }
}

This library is awesome!
but when I load 16 bit model, I got this error:
Unwrap failed: original mesh (Natural ar0(Clone)) has 16 bit indices, but unwrapped requires 32 bit.
Thanks for you sharing!
