ios - 从控制台读取行作为 Swift iOS 中 2D 数组的输入

Question

尝试从控制台读取由单个字符空格分隔的整数行到二维数组中。我尝试过使用 split(separator:maxSplits:omittingEmptySubsequences:) ，但不能转换为整数。

必须从控制台读取作为输入的二维数组如下所示

1 1 1 0 0 0
0 1 0 0 0 0
1 1 1 0 0 0
0 0 2 4 4 0
0 0 0 2 0 0
0 0 1 2 4 0

这是我尝试过的代码

var arr = [[Int]]()
for i in 0 ... 5 {
    var a = readLine()?.components(separatedBy: " ")
   var arr[i] = [a?.split(separator: " ", maxSplits: 1, omittingEmptySubsequences: false)] as? Int

}

错误是

cast from '[ArraySlice]?' to unrelated type 'Int' always fails

Answer 1

for i in 0...5 {    
  var aux = [Int]()

  readLine()?.split(separator: " ").map({
    aux.append(Int($0)!)
  })
  arr.append(aux)
}
