    the line I was able to get accepted by xcode was:

    tipCalc.amountBeforeTax = Float(amountBeforeTaxTextField.text!)!

    I haven't gotten to the end of the project but it allowed me to continue to the next step.

    Hey guys, thanks for the hard work putting these videos up. It is a really good sequence. I'm having a problem minute 11:00 when you setup the func calcTIp , when i setup the NSString it says "value of optional type SString not unwrapped, did you mean to use '!' or '?'". THen i clicked it to fix automatically, it seemed to world it doesnt build the interface anymore, some error occur and there are a lot of threads in a blue texted screen instead.. What should i do? Would it be because my version of xcode is different? i/m on version 7.2
