I solve it As a Fedora 32 user, i run those commands in terminal and they solved my problem

1st

sudo dnf install libcurl4-openssl-dev

2nd

sudo dnf groupinstall 'Development Tools' 'Development Libraries'

3rd

sudo dnf install zlib-devel libyaml-devel openssl-devel gdbm-devel readline-devel ncurses-devel libffi-devel curl git openssh-server redis libxml2-devel libxslt-devel libcurl-devel libicu-devel python

then in RStudio i typed

install.packages("swirl", dependencies = TRUE) and it worked successfully

to check##

library("swirl")
