### Global configuration

# Enable rules which are not in the default set
opt_in_rules:
  #  - anyobject_protocol                             # Prefer using `AnyObject` over `class` for class-only protocols.
  #  - array_init                                        # Prefer using `Array(seq)` over `seq.map { $0 }` to convert a sequence into an Array.
  #  - attributes                                        # Attributes should be on their own lines in functions and types, but on the same line as variables and imports.
  - block_based_kvo                                   # Prefer the new block based KVO API with keypaths when using Swift 3.2 or later.
  - class_delegate_protocol                           # Delegate protocols should be class-only so they can be weakly referenced.
  - closing_brace                                     # Closing brace with closing parenthesis should not have any whitespaces in the middle.

libdispatch efficiency tips

The libdispatch is one of the most misused API due to the way it was presented to us when it was introduced and for many years after that, and due to the confusing documentation and API. This page is a compilation of important things to know if you're going to use this library. Many references are available at the end of this document pointing to comments from Apple's very own libdispatch maintainer (Pierre Habouzit).

My take-aways are:

• You should create very few, long-lived, well-defined queues. These queues should be seen as execution contexts in your program (gui, background work, ...) that benefit from executing in parallel. An important thing to note is that if these queues are all active at once, you will get as many threads running. In most apps, you probably do not need to create more than 3 or 4 queues.

• Go serial first, and as you find performance bottle necks, measure why, and if concurrency helps, apply with care, always validating under system pressure. Reuse
