== Why is this an issue?

When a method doesn't match it's ``++super++`` method in visibility (``++public++``, ``++protected++``, ...), malicious callers could take advantage of the over-broad access offered by the child class to undermine the application.


=== Noncompliant code example

[source,swift]
----
public class Parent {

  protected void foo() {
    //...
  }
}

public class Child extends Parent {

  public void foo() {  // Noncompliant
    // ...
    super.foo();
  }
}
----


=== Compliant solution

[source,swift]
----
public class Parent {

  protected void foo() {
    //...
  }
}

public class Child extends Parent {

  protected void foo() {
    // ...
    super.foo();
  }
}
