The iPhone XS Max is a relatively new device and the device setting is not yet available in the predefined list of devices.

One can edit this to add/remove devices from the drop-down list. Only the devices that are ticked in the list shown are visible in the drop-down. All available devices are listed on selecting the Edit button. Only a subset of available devices is shown in the drop-down. You can switch between them to see how the site will render on various devices. In this mode, the devices drop-down list shows all the predefined list of mobile device lists. Use the Chrome DevTools to simulate mobile devices and load the website in mobile view. In this post, we will see how we can use Google Chrome Browser to take screenshots in the different resolution that the App Store requires for app submission. The mobile app is the website packaged as a Cordova application. I had none of the iOS app development related applications setup and had to get this done as soon as possible. I had just moved to a new client and was to push an update for their existing mobile application. When submitting an app to the iOS App Store, it now mandates to upload screenshots for iPhone XS Max or the 12.9-inch iPad Pro.
