When you’re unboxing a new iPhone, it’s time to think about how you’ll move your digital life from your old iPhone to the new one. If your old iPhone is running iOS 11, you can use Quick Start, a new iOS 11 feature that makes the transfer easy. Just turn on the new iPhone, set it next to the old one, and tap Continue when asked whether you want to use your Apple ID to set up your new iPhone. An animation appears on the new iPhone for you to scan with the old iPhone—once you’ve done that, follow the rest of the instructions to enable Touch ID or Face ID and then restore your data and settings from your most recent iCloud backup (you can update the backup first if necessary). Leave the two iPhones next to each other while data is being transferred, and if possible, keep the new one plugged in and on Wi-Fi after setup so it can download your apps, photos, and music from Apple’s cloud-based services.
An extremely welcome under-the-hood change in iOS 11 and macOS 10.13 High Sierra is that Photos facial recognition syncs across iCloud Photo Library. Previously, people you identified on one of your devices remained unidentified on others. But what if Photos now identifies the same person twice, such that they have two separate entries in the People album? Just drag one entry on top of the other, in either the Mac or iOS version of Photos, and agree that they’re the same person when Photos asks.
You’ve undoubtedly seen those odd-looking square QR codes on product packaging, a business card, or a flyer. In the past, you needed a special app to scan a QR code to see what Web URL, contact card, Wi-Fi network, or other piece of information it held. In iOS 11, though, you can just point your iPhone or iPad camera at a QR code—no need to take a picture! Then tap the notification that appears at the top of the screen to display whatever data was encoded by the QR code.
