Can someone help? I can't figure this out. Thank you so much.

// Enter your code below
var results: [Int] = [] 

for multiplier is 1...10 { 
   results.append(multiplier*6)
   }

The keyword with fast enumeration (for-in loops) has to be ´in´ not ´is´.

for multiplier in 1...10 { 
   results.append(multiplier*6)
}

Check the preview in Treehouse, it should indicate this syntax error. Moreover, I strongly recommend testing your code in a playground in Xcode. It makes life so much easier. Talking about code completion, inline error descriptions and warnings ;)

Hope that helps :)
