11:28 could also use count from the array and just -1 if you have many items :)

Hi, ive been watching your vids and ive followed step by step with no issues till now... for some reason, my screen looks exactly like yours and im positive ive followed everything properly, but for some reason, when i was trying to test the app out on my simulator it wouldnt work... and the only differences i can spot is that my 4 dots on lines "13, 14, 15&16" are still highlighted, but yours arent.. ive gone back to see if i missed any steps but it all seemed correct, please help

Chris, how to I get angle and how to get curly braces on Mac? Thanks!

[chisomodimmegwa]

ok i already solved the disappearing card issue. now problem is, as i press the deal button, sometime one of the card will disappear

[tipfertilizer]

Could you help to check why my code got error? (just want to try a new way)

var cardNames = ["ace", "jack", "queen", "king"]

for item in 2...10 {
cardNames =
}

[yonitbousany]

Thanks for these videos! I had an idea to, rather than type each card number separately in the array, do something like this:
let Number = arc4random_uniform(9)+2
let cardNames = ["ace", "card\(Number)", "jack", "queen", "king"]

But I'm getting an error: "Cannot use instance member 'Number' within property initializer; property initializers run before 'self' is available". Can you explain?

[fiores]

hi Chris, I got this message when I change "card\(leftNumber)" to (cardNames[leftNumber])



Cannot subscript a value of type '[String]' with an index of type 'UInt32'


what do you think the problem?

[ProCodMinecraft]

Any one know how to fix the problem when I deal the cards and one side becomes blank with no card?

[iankalter]

I've been following along on my computer and when I ran my code I would occasionally have no card show up on either the left, right, or both sides as I kept hitting the Deal button. I can't figure out why.

[chisomodimmegwa]

when i clicked the deal button, my cards disappeared

[chisomodimmegwa]

alright i saw the problem. card1 doesnt exist and then i out it there XD
