iOS automatic version script
#!/bin/sh
###
# Version: $Major.$Minor.$Commit
#
# How it works:
# 1. To roll minor number, tag each App Store release with a message.
# 2. To roll major number, create an additional tag on the last App Store
# release (e.g. "2.17.9") with new major number (e.g. "3").
# 3. `Release` builds require a clean working directory.

Draft of Swift Evolution Proposal for Case Blocks

Enum Case Blocks

  • Proposal: SE-XXXX
  • Authors: Tim Shadel
  • Review Manager: TBD
  • Status: TBD

Motivation

Add an optional syntax to declare all code related to a single case in one spot. For complex enums, this makes it easier to ensure that all the pieces mesh coherently across that one case, and to review all logic associated with a single case. This syntax is frequently more verbose in order to achieve a more coherent code structure, so its use will be most valuable in complex enums.

Here are some things you can do with Gists in GistBox.
// Use Gists to store code you would like to remember later on
console.log(window); // log the "window" object to the console

Empty Pod For Watch Extension

* If your watch extension doesn't need any of it's own exclusive pods,
* it won't have its header search path set to see any of the dependencies
* of embedded frameworks it relies on. This fixes that without duplication.

A Facebook post in HTML and hyper+json.

Compare & Contrast

HTML, Hyper+JSON, and Data as JSON

OK. Everyone's got LOTS of questions and emotions around how to use hyper. I want to answer them, but first I want to walk you through a comparison exercise.

  1. Take a look at the screenshot below of a typical Facebook post.

    Think about the ways you could navigate or interact with this FB post, based only on what you see. Any kind of interaction you take either moves the view to another object, or it alters the data of this object.
