Apple has posted an update to its developer forum encouraging developers to test their apps in an iPhone X simulator ahead of the device’s launch.

The company is touting its accompanying App Store redesign and asking developers to submit new screenshots geared toward the iPhone X’s display size along with updated metadata to include on the new product pages.
Testing the apps is also expected to expose issues with the Super Retina display and adaptive layouts, but we’ll have to wait until users actually get their hands on the new devices before we’ll know if there are any problems with non-updated apps.
