swift - Compiler error: could not find member 'subscript' with && - 


 var card:[[int]] = bank[numberofmarked].card;    if ((card[0][0] == 0) && (card[1][1] == 0) && (card[2][2] == 0) && (card[3][3] == 0) && (card[4][4] == 0))     {      return true;      }

i getting error "could not find member 'subscript' , compiler pointing last &&.

i'd file bug -- i'm getting error well: note: expression complex solved in reasonable time; consider breaking expression distinct sub-expressions. nothing wrong expression, use in swift right you'll need break couple bool variables:

let firsttwo = card[0][0] == 0 && card[1][1] == 0 let lastthree = card[2][2] == 0 && card[3][3] == 0 && card[4][4] == 0 if firsttwo && lastthree {     return true }
