Because force casting (``as!``) does not perform any type safety validations, it is capable of performing dangerous conversions between unrelated types. When the types are truly unrelated, the cast will cause a system crash.

== Noncompliant Code Example

----
foo as! MyClass  // Noncompliant
----

== Compliant Solution

----
foo as? MyClass
