Array as a dictionary value in swift language -

-

i have following swift dictionary

var list = [     2543 : [ "book", "pen" ],    2876 : [ "school", "house"] ]

how can access array values ?

println(list[2543][0])

the above code gives error "could not find member subscript"

and should print "book"

note subscript returns optional. have force unwrapping:

println(list[2543]![0])

or use optional chaining

println(list[2543]?[0])
