It looks like Xcode 27.1 is needed to test the iPhone Duo resizability - and that hasn’t been uploaded yet.<\/p>\n<\/blockquote>\n\n

Cupertino and Friends™️ dropped six new videos over developing, designing, and crafting great apps for the nascent device:<\/p>\n

  2. Prepare your app for iPhone Duo<\/a><\/li>\n
  3. Raise the bar with iPhone Duo<\/a><\/li>\n
  4. Strike a pose with adaptive layouts on iPhone Duo<\/a><\/li>\n
  5. Leverage multiple displays and scenes on iPhone Duo<\/a><\/li>\n
  6. Build a great camera experience for iPhone Duo<\/a><\/li>\n<\/ol>\n<\/blockquote>\n\n

    In the Duo dev video, they describe how text buttons can’t be moved to the new vertical sidebar, as opposed to icon buttons.<\/p>\n

    I wonder if that’s one of the reasons Liquid Glass pushed hard for icon buttons, even though these are harder to understand; they make the vertical layout possible at all.<\/p>\n<\/blockquote>\n\n

    Totally confusing to me how the toolbar is ordered completely different between both modes here.<\/p>\n<\/blockquote>\n\n

    I think the problem with the iPhone Duo for developers is mostly that it does not create any new opportunities in the form of a new market or a new audience.<\/p>\n<\/blockquote>\n\n
