Swirl: Swirl not updated yet! Couldn't find contains() in "purrr" package.
There's a problem in the following course:
Mastering Software Development in R
Course 2: Advance R Programming.
Week 2: Quiz Portion.
OS: macOS Sierra 10.12.6
R Version: 3.4.1
Swirl Version: 2.4.3
One of the quiz questions (in the completion of 69% of the total quiz) in the above mentioned swirl course still asks to answer the question regarding contains() which we cannot find in purrr package anymore. I am not able to proceed further. Every time, I try to solve the problem, I stuck there by getting an error saying:
Error in contains(random_ints, 45) : could not find function "contains"
Could anyone please help me proceed this question?

This should now be fixed if you reinstall the course.

I've just bumped into the same problem. I didn't want to lose all the previous swirl work so I just defined a function like this:
has_element <- function(x,y){contains(x,y)}
and then used it as swirl expected it:
has_element(random_ints, 45)
and passed ... :)
