Looking at the set of methods in a class, struct, enum, or extension and finding two methods
that differ only by capitalization is confusing to users of the class. It is similarly confusing to have a method and a field or a case which differ
only in capitalization.
Code examples
Noncompliant code example
class SomeClass {
var lookUp = false
func lookup(){ } // Noncompliant; method name differs from field name only by capitalization
func lookUP(){ } // Noncompliant; method name differs from field and another method name only by capitalization
}
Compliant solution
class SomeClass {
var lookUp = false
func getLookUp(){ }
}
