# TexPad Biblatex citing not working

I just started using TexPad but citing is not working. Everything worked fine in Overleaf. But in TexPad citation just doesnt work. I dont get any errors. This is how the start of my document looks like

\documentclass[11pt]{article}
\usepackage[utf8]{inputenc}
\usepackage{graphicx}
\usepackage[margin = 4cm, top = 2cm, bottom = 2cm]{geometry}
\renewcommand{\figurename}{Bild}
\renewcommand{\contentsname}{Inhaltsverzeichnis}
\setlength{\parindent}{0pt}
\usepackage{url}
\usepackage[section]{placeins}
\usepackage{biblatex}
\bibliography{zitat}

\title{Title}
\author{Jango}
\date {05.02.2019}

\begin{document}


This is how my zitat.bib file looks like
