Match filename pattern with -f

Hello All,
I have two issues.
1).I want to check if directory exists and inside that if file exists with today's date minus one. I can check directory exists but how can i check only a pattern of filename in that directory.Name of file is files-20170105-09.gz.
2).Also i want to exit immediately if directory is not present. Is exit 0 correct. Please help.
Code:
dir=`date "+%Y%m%d"`
filename="files-`date -d '-1 day' '+%Y%m%d'`"
echo "$filename"

[[ -d "$dir" ]] && echo "Dir exists $dir" || echo "dir $dir doesnot exists" ||  exit 0

[[ -f '$dir/$filename*' ]] && echo "Filename $filename is correct" || echo "Filename is not correct"
