XCode 7, the toInt() is not available?

hi... I'm trying to run through the example in the video but in XCode 7 it wont let me write this statement: if let culprit = (findApt("404"))?.toInt() { sendNoticeTo(aptNumber: culprit)

}

error says 'toInt()' is unavailable: Use Int() initializer

uh yeah, what do i do?

Hello Ian Hicks,

Yes, toInt() is no longer supported. Use Int() instead.

if let culprit = findApt("404") {
    sendNoticeTo(aptNumber: Int(culprit)!)
}

Hope this helps!
