CodePudding user response：

For a given dictionary, use the removeValue(forKey:) method.

E.g.

var d = ["hello": "world", "foo": "bar"]
print(d)
// ["hello": "world", "foo": "bar"]
d.removeValue(forKey: "hello")
print(d)
// ["foo": "bar"]

Pair this with a for loop to (for example) remove the "name" key from every element in student.

for var s in student {
  s.removeValue(forKey: "name")
}
