May be a nitpick but consider not naming an instance of an array 'array', but instead something like 'numbersToBeSearched' or just 'numbers' can be fine. I'm just learning Swift but have experience in other langs, and that raises an immediate code smell for a few reasons..

Hi Sean Allen. i am a big fan of yours. I just subbed today coz I dont use youtube when I am logged in. btw, I just logged in to request you to post some videos related to app development lifecycle. Like, how to plan the app, how to organize the codes, basically just how you do it.

Thanks. big help. keep it up.

Hi Sean, I was just wondering when I should and should not use global variables and functions. Is it better to just put them in a class and access them using an object?

Hey is it possible to to make a tableview containing a list or an array of Strings and Textfields all In the same table..Instead of having one tableview for an array of Strings or another tableview with just textfields.

would the interviewer likely ask you to make it generic if you got it right for Int's?
