Key word 'as' not working the same as in these videos.

Whenever the key word 'as' has been used in these videos I have had to follow it with a '!' operator, otherwise I get an error. Is this due to an update with Xcode or is there something I am doing wrong?

Also, if this is correct, will this lead to the finished app behaving differently?

Hi Ian

I seem to recall having the same issue. I think the reason is just that in the videos, Pasan uses Swift 1 and right now we are using Swift 2 - which is probably the reason for the difference. I did however get through all the videos without any issues when using as!

Happy coding :-)

This is the video I am referring to, and the same situation occurred previously in the same tutorial.

I will link the exact code later on today on my lunch break! :)
