Inline adoc files when they are included exactly once. Also fix language tags because this inlining gives us better information on what language the code is written in.

== Why is this an issue?
|
|
|
|
If you only want one instance that matches certain criteria out of a collection, it's far more efficient to grab the first matching item than it is to fully filter the collection for your criteria and then only use a single value.

=== Noncompliant code example
|
|
|
|
[source,swift]
|
|
----
|
|
let one = arr.filter { $0.containsString("yo") }.first // Noncompliant

|
|
|
|
=== Compliant solution
|
|
|
|
[source,swift]
|
|
----
|
|
let one = arr.first(where: { $0.containsString("yo") })
