我正在尝试过滤字典数组。以下代码是我正在寻找的场景的示例
let names = [
[ "firstName":"Chris","middleName":"Alex"],
["firstName":"Matt","middleName":""],
["firstName":"John","middleName":"Luke"],
["firstName":"Mary","middleName":"John"],
]
最终结果应该是一个具有中间名的数组。
最佳答案
这成功了
names.filter {
if let middleName = $0["middleName"] {
return !middleName.isEmpty
}
return false
}
