swift 如何在swift中制作一个二维数组

Posted 2021-05-19

struct twodarray {
    
    static func intarr(width:Int, height:Int)->[[Int]] {
        var twod = [[Int]]()
        var row = [Int]()
        for _ in 1...width {
            row.append(0)
        }
        for _ in 1...height {
            twod.append(row)
        }
        return twod
    }
}
