Apple has removed support for older 32-bit applications in the new iOS 11, which was to be expected after the 10.3 update added the ability to detect apps that are still running 32-bit processes on your iPad, iPhone, or iPod touch. Apple even excluded restore images for 32-bit devices such as the iPhone 5 and iPad (4th gen) in the iOS 10.3.2 beta 1 update for developers, so this shouldn't be a surprise.
In iOS 10.3, when you try to open a 32-bit app, you'll get the message: "This app will not work with future versions of iOS. The developer of this app needs to update it to improve its compatibility." You'll still be able to use the app (if it even works because it's so old), but in iOS 11, it won't even open the app. The message will read: "The developer of this app needs to update it to work with iOS 11."
Thankfully, there's a hidden tool in iOS 10.3 and higher that lets you find all of the 32-bit apps on your device. So before your favorite apps become obsolete (or if they already are), I'll show you how to see which ones are outdated, and even how to contact the developer to get them to update their apps to the new 64-bit architecture.
iOS 10.3 has made it easy to check for any outdated 32-bit apps. Simply head to the "General" menu in Settings, then tap "About," and choose "Applications." A list of outdated apps should now automatically show up to give you notice.
All hope is not lost for 32-bit app lovers, as apps that are not optimized for 64-bit will still likely work with older iPads and iPhones whose firmware versions max out at or below iOS 10.3. The iPad 2 and iPad mini (1st generation), for example, will only go up to iOS 9.3.5. The iPhone 5 and 5c, the last 32-bit phones made by Apple, are not included in the iOS 11 update.
To check, open Settings. Tap on General. Tap on About, and select Applications. This brings up a list of the installed apps that are 32-bit.
The identification tool now in Settings in iOS 10.3 is a good start. However, Apple needs to be more forthcoming about this in the App Store, as well as giving users a clear identification of which apps are 32-bit in iTunes before the support is fully dropped.
Since 2015, apps have been required to run on 64-bit systems to be approved for the App Store, hinting that Apple plans to eventually drop support for 32-bit applications altogether in favor of the 64-bit architecture that was introduced with the iPhone 5s. iOS 10.3 leaves no doubt that this is Apple's intention, as it comes with a tool that identifies 32-bit apps and explicitly says, "these apps may slow down your iPhone and will not work with future versions of iOS if they are not updated. If no update is available, contact the app developer for more information." A warning will also pop up any time a 32-bit app is launched. For now you can continue using these apps, but chances are they will not work on iOS 11 which will likely debut this fall with the new iPhone and only run on 64-bit devices which include:
Aside from the imminent obsolescence of 32-bit apps, running them can also slow down your iPhone running the current iOS. iOS comes with system framework (kernel, libraries, etc.) for both 64-bit and 32-bit processors. A 64-bit device will automatically run on the 64-bit framework, but if a 32-bit application is launched, the 32-bit framework will load as well, putting more strain on system resources. So unless you are really attached to your 32-bit apps, you probably want to get rid of them, especially if you plan to update to iOS 11 when the time comes. Here's how to identify your 32-bit apps in iOS 10.3:
To assign categories, visit the Pricing and Availability section for your app in App Store Connect. If a category applies to your app, select it at the app level to apply it to the app and its associated in-app purchases. You can also manage each in-app purchase individually. Your selections will be applied to future transactions. If you choose not to make any changes, your apps and in-app purchases will be assigned the App Store software category at the same tax rate used today. Adjust these settings at any time as the characterization of your apps or in-app purchases evolve or as tax legislation changes.
As the owner of two iPhones, an iPhone 6 and an iPhone 5c both on iOS 10.3.3, both containing the same apps, I have seen App Compatibility function on the iPhone 6 and saw compatibility warnings for some apps, but cannot get it to work on the iPhone 5c for those same apps.
iOS 11 is on the way later this year, and many believe its release will spell the death-knell for 32-bit apps. Especially since iOS 10.3 offers up a powerful hint that the end is within sight. (As seen below.)
Apple announced iOS 10 on June 13, 2016, at its annual Apple Worldwide Developers Conference (WWDC) event, and it was released to the public on September 13, 2016, alongside the iPhone 7 and iPhone 7 Plus. With this release, Apple dropped support for devices using an A5 or A5X processor: the iPhone 4S, the iPad 2, iPad (3rd generation), iPad Mini (1st generation), and iPod Touch (5th generation) due to hardware limitations, ending software support for iPhones and iPads with 30-pin connector and 3.5-inch display. iOS 10 has limited support on devices with 32-bit processors: the iPhone 5, iPhone 5C, and iPad (4th generation). However, the iPhone 5S onwards, iPod Touch (6th generation), iPad Air onwards, and the iPad Mini 2 onwards are fully supported. The release of iOS 10.2.1 brought support for the iPad (5th generation), and iOS 10.3.2 brought support for the iPad Pro (10.5-inch) and the iPad Pro (12.9-inch, 2nd generation). iOS 10.3.3 is the final supported release for the iPhone 5C and the Wi-Fi-only iPad (4th generation). iOS 10.3.4 is the final supported release for the iPhone 5 and the Wi-Fi + cellular iPad (4th generation). iOS 10 is the final iOS version to run on 32-bit processors. It is also the final version of iOS to run 32-bit apps. It was succeeded by iOS 11 on September 19, 2017.
2. Check if your apps are supported. iOS 11 won't support every app that runs on iOS 10, because it's a 64-bit operating system, and some apps haven't been updated and are still 32-bit. If your iPad is running iOS 10.3 or later, you can check to see if you've got any 32-bit apps installed by opening the settings app, tapping General, tapping About and tapping Applications.
This release uses guzzle 7. The complete bundle contains several app updates that were migrated from guzzle 5 to guzzle 7. When using the minimum bundle, those apps can be downloaded from the marketplacte. Please check any non-standard apps for guzzle 7 compatibility. If in doubt, disable these apps before upgrading.
With ownCloud 10 the File Drop feature has been merged with publiclink permissions. This kind of public link does not give recipientsaccess to any content, but it gives them the possibility to dropfiles. As a result, it might not always be desirable to enforcepassword protection for such shares. Given that, passwords for publiclinks can now be enforced based on permissions (read-only, read &write, upload only/File Drop). Please check the administration settings`Sharing` section and configure as desired.
If you don't have the option to tap into the "Applications" section, then you're in a good spot, as it means all your apps are 64-bit and will work with iOS 11. Most people will probably see at least a few apps here. In my case, 60 of 337 apps were listed as being incompatible with iOS 11 when I checked the list in July.
where --extra-arch selects only those checks which depend onthe installed code and not those which analyse the sources. (Ifmultiple sub-architectures fail only because they need differentsettings, e.g. environment variables, --no-multiarch may needto be added to the INSTALL lines.) On Unix-alikes thearchitecture to run is selected by --arch: this can also beused on Windows with R_HOME/bin/R.exe, but it is more usualto select the path to the Rcmd.exe of the desiredarchitecture. 2b1af7f3a8
