11,033 PointssendNoticeTo() error in Swift 2
rpl.swift:86:19: error: expected parameter type following ':' func sendNoticeTo(#aptNumber:Int) { ^ '
so basically func sendNotice(#aptNumber:Int){ } doesn't work in swift 2

The # for parameter names isn't supported anymore in Swift 2. If you want the function to have the same external name as the local name, you just write the parameter name twice. However, this is only for the first parameter because if no external name is specified - Swift will use the local name as the external name by default.
func sendNotice(aptNumber aptNumber:Int){
}
Good Luck

The biggest difference I have noticed so far is regarding how errors are handled. The Swift 2.0 course on Error Handling is a great course on this topic. I believe that Treehouse also has a Workshop that should answer this question for you in more detail: https://teamtreehouse.com/library/whats-new-in-swift-20
However, I haven't gotten to watch it myself yet. Hope this helps, good luck!
