Instead of 1 Theorem. I want to write 1 Theorem in front of the first theorem and analogously in front of succeeding theorems. How can I get rid of the dot?
Here is a MWE:
\documentclass{article}
\usepackage{amsthm}
\swapnumbers
\newtheorem{theorem}{Theorem}
\begin{document}
\begin{theorem}
\end{theorem}
\end{document}

\xpatchcmd{\proof}{\@addpunct{.}}{\@addpunct{:}}{}{}by\xpatchcmd{\theorem}{\@addpunct{.}}{\@addpunct{}}{}{}should do the trick – Romain Picot Sep 22 '15 at 15:25;-)– Romain Picot Sep 22 '15 at 15:32
