Describe the bug

DiscouragedDirectInitRule should apply to NSError(). Directly initializing NSError results in a runtime warning:

-[NSError init] called; this results in an invalid NSError instance. It will raise an exception in a future release. Please call errorWithDomain:code:userInfo: or initWithDomain:code:userInfo:. This message shown only once.

  If so, paste their relative paths and respective contents. no

• Do you have a sample that shows the issue? Run echo "[string here]" | swiftlint lint --no-cache --use-stdin --enable-all-rules

  complex, you can use swiftlint lint --path [file here] --no-cache --enable-all-rules.
