My code...
for number in 1...10 { println("(number) * 7 = (number*7)") }
And I get this error...
swift_lint.swift:5:30: error: 'countElements' has been renamed to count let range = NSMakeRange(0, countElements(string)) ^~~~~~~~~~~~~ count Swift.countElements:1:36: note: 'countElements' has been explicitly marked unavailable here @availability(*, unavailable) func countElements(x: T) -> T.Index.Distance ^

Are you putting the slashes before the (number) in the code? Otherwise it looks good and works for me.

11,956 PointsMichael,
I would say to refresh and go back to the quiz and see if it will accept your answer then - Sometimes that has happened to me :)

2,878 PointsA refresh did not work. I also cleared all history and cookies. It seems like someone clobbered the backend.
This is the last module before going on to the next track.
Know any way how to skip it and move on?

2,878 PointsDisregard the last question. I found that I can just take the next course off-track.

2,878 PointsAh, yea, the slashes are there. The formatting of the slashes did not take very well in the forum. I think it's a problem with the backend, since I get the compile error even with a simple var statement.
