== Why is this an issue? Shared coding conventions allow teams to collaborate efficiently. This rule checks that all enumeration member names match a provided regular expression. === Noncompliant code example With default provided regular expression: ``++^[a-z][a-zA-Z0-9]*$++`` [source,swift] ---- enum SomeEnumeration { case SomeMember // Non-Compliant } ---- === Compliant solution [source,swift] ---- enum SomeEnumeration { case someMember } ---- ifdef::env-github,rspecator-view[] ''' == Implementation Specification (visible only on this page) include::../message.adoc[] === Parameters .format **** ---- ^[a-z][a-zA-Z0-9]*$ ---- Regular expression used to check the enumeration value names against. **** endif::env-github,rspecator-view[]
