Texifier’s live typesetter does not support rendering EPS files.
If you want to typeset vector graphics, please export them as PDFs rather than using the EPS format. PDFs can be included the same as any other graphics file, using the graphicx package, and the \includegraphics{} command.
iOS lacks a PostScript interpreter and supporting EPS figures without such support in the live typesetter is a significant undertaking, something we have not been able to schedule thus far.
If you cannot convert your EPS files to PDF, an alternative on iOS is to use the cloud typesetter.
