"I found no \citation commands while reading myFile.aux"

As mentioned in the comments, you should run biber to compile your bib file as you have used biber as the backend.

\usepackage[style=authoryear,backend=biber]{biblatex}

Here are the commands to compile your myFile.tex and your .bib files:

pdflatex myFile
biber myFile
pdflatex myFile

I have the same problem with TeXstudio, and backend=biber does not work for me. If you're using TeXstudio too, you have two options:

1. change the default bibliography tool in TeXstudio settings (Options > Configure TeXstudio > Build > Default Bibliography Tool)

2. add this line at the beginning of the document

   % !BIB TS-program = biber
