The XD team just released awesome improvements to design mode in the March Update with the support for copy and paste from Photoshop and Illustrator.

However, one cannot copy and past type from Photoshop to XD without copying the type as a raster or an SVG.

A similar problem was addressed for Illustrator here:

It would be great if the solution for illustrator - the ability to copy text and paste it in XD as a text element - was made available for photoshop.
