iOS Device Summary: September 2016 Updates

I’ve updated my iOS Device Summary with hardware announced at the Apple event on September 7, 2016.

Check out the iOS Device Summary page for more info about the idea behind the summary as well as PDF downloads—including optimized files for printing.

A few notes:

Sometimes fall brings new iOS hardware across all product lines. This year, only new iPhone versions were released.

In terms of legacy hardware support, iOS 10 drops support for devices running the A5 and A5X processor. This includes iPhone 4S , which means that there are no devices with a 3.5-inch screen that support iOS 10.

.Don’t feel badly for devices with the A5 chip—they have had a very good run. The iPhone 4S debuted running iOS 5 and iPad 2 debuted with iOS 4.2.1. Both were supported up through iOS 9.

Time will tell if the next version of iOS drops support for A6 and A6X devices. When support for those devices is dropped, iOS devices will be 64-bit only.

In the meantime, of course, it is important to test on older devices running the oldest version of iOS that you support.

I hope you find this version of the chart helpful. •

tvOS and watchOS Device Summary: April Edition

After updating the popular iOS Device Summary in March, it seemed the beginning of April would be a good time to introduce summaries for devices running the most recently introduced Apple operating systems: tvOS and watchOS.

I hope you find these as useful as I have. •

iOS Device Summary: March 2016 Updates

I’ve updated my iOS Device Summary with hardware announced at the Apple event on March 21, 2016.

Check out the iOS Device Summary page for more info about the idea behind the summary as well as PDF downloads—including optimized files for printing.

A few notes on the newly introduced hardware:

The introduction of the 9.7-inch iPad Pro means even more users will be putting the Apple Pencil and Smart Keyboard through its paces. Even if your app is not a drawing or text-centric, you might consider having at least one size of iPad Pro with these accessories for development and testing.

The iPhone SE brings paris a well-established iOS screen resolution with a faster processor. From a testing perspective, apps that perform well on previous 4-inch devices should perform even better on the new hardware.

Only the display of the 9.7-inch iPad Pro has the new True Tone feature.

The Night Shift feature introduced in iOS 9.3 is available to devices using at least an A7 chip—every device on the 64-bit side of the divide on the summary chart.

I hope you find this version of the chart helpful. •

iOS Device Summary: Fall 2015 Updates

I’ve updated my iOS Device Summary with hardware announced at the Apple event on September 9, 2015. This edition drops iOS 5 and A4-based devices to make way for iOS 9 and the A9 and A9X.

(This update has taken a little while—I’ve been busy helping to build a new cloud computer at Upthere.  I’m excited to say that we launched yesterday. I encourage you to learn more and join the beta at upthere.com.)

Check out the iOS Device Summary page for more info about the idea behind the summary as well as PDF downloads—including optimized files for printing.

The biggest news this fall is the iPad Pro, which introduces the largest iOS screen size ever, but also two new Apple accessories that may be important to test your app with: the Apple Pencil and the Smart Keyboard. On the other new devices, iPhone and iPad screen resolutions remain the same and get faster processors. From a testing perspective, things that perform well on last year’s models should perform even better on the new hardware.

It is also interesting to note that all of the devices that can run iOS 6 are on the 32-bit side of the processor divide.

I hope you find this version of the chart helpful. •

iOS Device Summary: A8 iPod Touch Update

I’ve updated my iOS Device Summary with the newly announced iPod touch.

You can check out the iOS Device Summary page for more info about the summary plus PDF downloads—including optimized files for printing.

For developers, the iPod touch has been a useful, relatively inexpensive compact device for testing. The previous model was released almost four years ago and sits at the very low end of devices that support iOS 8 and iOS 9.  The new sixth generation iPod touch is a welcome addition as a more affordable testing device with a recent 64-bit processor.  Like previous generations, the new iPod touch has a 4-inch display, so an iPhone is still needed for on-device testing of larger screen resolutions.

It is interesting to note that every iOS device that Apple currently sells, except the iPhone 5c, has a 64-bit processor.

This also means that if you need to acquire older models for testing iOS 8 and iOS 9, you will need to turn to refurbished or used devices.

I hope you find this version of the chart helpful. •

iOS Device Summary: iOS 9 Update

I’ve updated my iOS Device Summary with the iOS 9 info Apple has publicly posted.

Check out the iOS Device Summary page for the rationale behind the summary plus PDF downloads—including optimized files for printing.

Some things to note from WWDC announcements and Apple product lineup changes:

All devices that support iOS 8 will also support iOS 9.

Apps are currently required to support both 32-bit and 64-bit processors. With iOS 9, the App Store will also accept apps that are 64-bit only. This allows developers to limit deployment of an app to more recent devices with faster CPUs and GPUs. The device summary now has a line showing where 32-bit ends and 64-bit begins.

Finally, devices for testing:

  • At $199, the 16 GB, 5th generation iPod touch is still the most affordable compact iOS 9 device
  • At $299, the 16 GB, WiFi iPad mini 2 is now the most affordable iOS 9 iPad
  • As of 6/19/15, the original iPad mini is discontinued—try used and refurbished devices for low-end iPad testing.

I hope you find this version of the chart helpful. •

Where I’ll be at WWDC 2015

I’ll be doing a few things next week at WWDC and wanted to pass along my schedule. Hope to see you at one or more of these happenings!

Monday: NeXTEVNT Fundraiser for the Cartoon Art Museum

NeXTEVNT Logo
I’ll be doing a short set of James Dempsey and the Breakpoints songs at this fundraising event at the Cartoon Art Museum.

This event has been a lot of fun each year, always with great speakers and plenty of time to meet and mingle with very interesting folks. If you are a fan of comics, cartoons, or animation — or have an interest in where the technology we use every day comes from — this is a great event for a great cause.

I highly encourage you to check out the details and come to the event.

I’ll be closing out the week at AltConf 2015 again this year with an easy-going look back at the announcements of WWDC 2015 and their possible implications in a session entitled So, That Just Happened.

This session is a talk about the week in review and not a set of James Dempsey and the Breakpoints songs.

However, there may also be a bit involving a ukulele.

A Busy WWDC 2015 Week

It will be a busy WWDC week as we walk around with our heads swimming trying to soak in all of the new announcements.

I hope you can make it out to one or more of these events!  And if you do, please say hello! •


Going Upthere

I’m very happy to announce that I have joined the team at Upthere.

Here’s the gist from upthere.com:

Our team is hard at work in Palo Alto, CA, building out the future of the cloud. We can‘t wait to tell you more, but right now we‘re working very quietly. Some really great engineers and designers who‘ve built some of the world‘s most successful products are already here.

Even though I’m now at a stealth mode startup, I’m not dropping completely out of sight.

I’ll still be speaking at conferences and James Dempsey and the Breakpoints will continue performing and writing new songs whenever inspiration strikes.

In fact, I’m gearing up for a spring tour that starts in England and then criss-crosses the USA. At each stop I’ll be speaking and performing in a Breakpoint Jam — a set of songs from our iTunes chart-topping album Backtrace.

I hope you are able to make it out to one of these excellent conferences. If you do, please say hello! •

Learning More About Xcode Build Settings with BuildSettingExtractor

Last week I posted about BuildSettingExtractor, a utility that makes it easy to pull the build settings out of an Xcode project file and into xcconfig build configuration files. (The post also mentions some xcconfig file benefits with links to ‘how to’ information. Read the earlier post here.)

I also wanted BuildSettingExtractor to be useful for anyone who wants to learn more about the build settings in their projects. To that end, the latest version, available on github, generates build setting descriptions gleaned from the installed version of Xcode.

For example:

// Framework Search Paths
// 
// This is a list of paths to folders containing frameworks to be
// searched by the compiler for both included or imported header
// files when compiling C, Objective-C, C++, or Objective-C++, and by
// the linker for frameworks used by the product. Paths are delimited
// by whitespace, so any paths with spaces in them need to be
// properly quoted. [-F]

FRAMEWORK_SEARCH_PATHS = $(DEVELOPER_FRAMEWORKS_DIR) $(inherited)
	

// Info.plist File
// 
// This is the project-relative path to the plist file that contains
// the Info.plist information used by bundles.

INFOPLIST_FILE = BuildSettingExtractorTests/BuildSettingExtractorTests-Info.plist

Inline Build Setting Info

To learn more about build settings, Apple provides the Build Setting Reference (Apple developer documentation links are notoriously fragile, just search for the document) as well as Quick Help in Xcode when a build setting is selected. (In Xcode choose View > Utilities > Show Quick Help Inspector (Cmd-Opt-2))

In addition to these ways of learning more, BuildSettingExtractor gleans the build setting info from Xcode and puts it inline in the generated xcconfig files. This has a few benefits:

  • Read about each build setting without selecting setting one by one in Xcode
  • Read about only the build settings currently set in your project and targets
  • Information about build settings is available wherever you are looking at the xcconfig file: github, text editors, diff tools, etc.

What if I don’t want this lovely but verbose feature?

If you want BuildSettingExtractor to generate pithy xcconfig files without the build setting info, Choose BuildSettingExtractor > Preferences… (Command-,) for the new preferences sheet and turn it off.

BuildSettingExtractor Preferences Sheet

Happy Building! (and a call for help)

I hope you find BuildSettingExtractor useful, either as a learning tool, or to get rolling with xcconfig files. If you do find it useful, please spread the word about it: https://github.com/dempseyatgithub/BuildSettingExtractor.

As for the call for help, if you would like to help out with a basic app icon for BuildSettingExtractor, the utility can emerge from the primordial world of the generic app icon. Contact me if you are interested. •
