I was doing some coding in iOS 12.2 Beta 4. I cracked this here on what a new iPod touch 7th generation could look like. HLipod is the 6th generation HLipod2 is a unreleased generation. *Notice no home button and it looks to be a full screen display.* @OnLeaks @stroughtonsmith pic.twitter.com/pXLzif5JMZ— Johnathan Mitchell (@jaymit2090tx13) March 8, 2019
The icon labeled "HLSipod2" on the right is shown beside the existing icon for Apple's current-generation iPod touch, suggesting that an unreleased seventh-generation iPod touch will inherit the design elements of Apple's flagship all-screen iPhones and do away with the Home button.
That said, the device in the icon doesn't have a notch and it also appears to be off-center, which could mean that it's being used by Apple as a placeholder in the iOS 12 beta. Either that, or it's not genuine at all.
In January, developer Steven Troughton-Smith discovered references in iOS 12.2 to an "iPod 9,1," which does not match up with any known iPod touch devices, suggesting it is a new next-generation model. However, the iPod listing in iOS 12.2 does not appear to have Face ID or Touch ID.
Last month, Apple analyst Ming-Chi Kuo said he expects a new iPod touch with a faster processor to launch in 2019, but Kuo made no mention of a possible redesign for the device.
Apple last updated the iPod touch in July 2015, and in July 2017 the company cut prices and reduced the number of storage capacity options.
Update: Developer and frequent iOS beta explorer Guilherme Rambo says "there is no such icon on iOS."
