Note

Apple will reject apps that are using private url schemes (Ugh, Apple....) if they are pretty much obvius. Some apps are rejected and others are not, so, be aware of this issue before implementing any of those URL's in your app as a feature.

Updates

  • [UPDATE 4] iOS 10 update: apparently settings now can be reached using App-Pref instead of prefs
  • [UPDATE 3] For now you just can use url schemes to open your apps's settings with Swift 3.0 (Xcode 8). I'll keep you informed when OS preferences can be reached
  • [UPDATE 2] The openURL() method of UIApplication is now deprecated. You should use application(_:open:options:) instead
  • [UPDATE 1] Not yet tested in iOS 10. It will fail because of policies changes in URL scheme handling.

A composable pattern for pure state machines with effects (draft v3)

A composable pattern for pure state machines with effects

State machines are everywhere in interactive systems, but they're rarely defined clearly and explicitly. Given some big blob of code including implicit state machines, which transitions are possible and under what conditions? What effects take place on what transitions?

There are existing design patterns for state machines, but all the patterns I've seen complect side effects with the structure of the state machine itself. Instances of these patterns are difficult to test without mocking, and they end up with more dependencies. Worse, the classic patterns compose poorly: hierarchical state machines are typically not straightforward extensions. The functional programming world has solutions, but they don't transpose neatly enough to be broadly usable in mainstream languages.

Here I present a composable pattern for pure state machiness with effects,

New stuff from WWDC 2016

Following the tradition from last year, here's my complete list of all interesting features and updates I could find in Apple's OSes, SDKs and developer tools that were announced at this year's WWDC. This is based on the keynotes, the "What's New In ..." presentations and some others, Apple's release notes, and blog posts and tweets that I came across in the last few weeks.

If for some reason you haven't watched the talks yet, I really recommend watching at least the "State of the Union" and the "What's New In" intros for the platforms you're interested in. The unofficial WWDC Mac app is great way to download the videos and keep track of what you've already watched.

If you're interested, here are my WWDC 2015 notes (might be useful if you're planning to drop support for iOS 8 now and start using some iOS 9 APIs).

iOSでデータを永続化する方法

How to save data in iOS

この投稿では、iOSのファイルシステムについて理解し、データを永続化(iCloud含む)する方法を紹介する。尚、サンプルコードは動かない可能性もあるので参考程度にして下さい。

iOS File System

アプリがファイルシステムとやり取り出来る場所は、ほぼアプリのサンドボックス内のディレクトリに制限されている。新しいアプリがインストールされる際、インストーラーはサンドボックス内に複数のコンテナを作成し、図1に示す構成をとる。各コンテナには役割があり、Bundle Containerはアプリのバンドルを保持し、Data Containerはアプリとユーザ両方のデータを保持する。Data Containerは用途毎に、さらに複数のディレクトリに分けられる。アプリは、例えばiCloud Containerのように、実行時に追加のコンテナへのアクセスをリクエストすることもある。

Using iOS 15 devices with Xcode 12.5 (instead of Xcode 13)
# The trick is to link the DeviceSupport folder from the beta to the stable version.
# sudo needed if you run the Mac App Store version. Always download the dmg instead... you'll thank me later :)
# Support iOS 15 devices (Xcode 13.0) with Xcode 12.5:
sudo ln -s /Applications/Xcode-beta.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/15.0 /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport
# Then restart Xcode and reconnect your devices. You will need to do that for every beta of future iOS versions
# (A similar approach works for older versions too, just change the version number after DeviceSupport)

Loading a Cocoa Framework in a Sketch Plugin

This is what Craft does:

function loadFramework(pluginRoot) {
  if (NSClassFromString('PanelsManager') == null) {
    var mocha = [Mocha sharedRuntime];
    return [mocha loadFrameworkWithName:'Panels' inDirectory:pluginRoot];
  } else {
    return true;
 }

Elegant handling of localizable strings in Swift. Note: This code is in Swift 2 and would need updates to be used in modern Swift.
let color = "blue"
let num = 42
localized("Colorless green ideas sleep furiously.")
localized("Colorless \(color) ideas sleep furiously.")
localized("\(num.formatted("%05d")) colorless green ideas sleep furiously.")
