Swift: Determine if array contains array [duplicate]

Question

Im trying to figure out how to check if array contains another array:

var grid: [[Int]]!
grid = []
grid.append([1,1])

if grid.contains([1,1]) {

}

but the line

if grid.contains([1,1]) {

throws the error:

Contextual type '@noescape ([Int]) throws -> Bool' cannot be used with array literal

Swift arrays doesn't conform to Equatable by default. But you can still compare them in the predicate:

if (grid.contains { $0 == [1,1] } == true) {

}
