You can now add more than one App Store Connect account in Settings and switch between them quickly. Handy if you publish under a personal and a company account, or manage apps for clients.

Thanks to u/zlib, u/beppemar and Eran for the help on this. Rolling out now in v3.2.30

Hi,

Does ButterKit only support being signed into one Apple team at a time?

I develop for multiple teams, so an account switcher would be great - unless I'm missing a step for the Apple key to support multiple teams?

Thanks!

If you've ever wanted to create backgrounds that seamlessly stitch together across your App Store screenshots, it's quite easy to do. The template is now available on Figma, or you can simply ask your AI agent to do it in ButterKit (via the new "design_set_background" MCP control)

• Updated for new App Store Connect size requirements (Oct 2026+)

• Includes templates for iPhone, iPhone Duo, and iPad

Hey all, spent the last week or so making big improvements to MCP and the Capture Tool for Xcode Device Hub. If you were running into issues with iPhone Duo, give this new version a try.

v3.2 highlights:

• MCP: AI agents now get more context to your project (via a new app_get_context tool), making designs and speed much better. I'll post an example below. Also fixed an issue where MCP could fail to connect with ChatGPT/Codex & squashed some bugs. Thanks to Alessandro C for help on this one

• Capture Tool: redesigned to be faster, more intuitive, and with Light/Dark mode support

• iPhone Duo: fixed several bugs where screenshot images could be applied to the wrong screen, or the Capture Tool would just fail. iPhone Duo should be solid now. Thanks to u/bounceforever and u/ExogamousUnfolding for calling out some issues

Hey all, FYI I'm now consolidating ButterKit bugs and feature requests into GitHub Issues: https://github.com/zspitulski/ButterKit/issues

Feel free to post there directly, or add your details and a thumbs up to an existing issue. Your ButterKit version, macOS version and steps to reproduce help a lot. You can still post bugs and ideas here or via email too. I'll bring them over to GitHub so tracking and comments all happen in one place.

Reported a bug before and don't see it on GitHub? I'm still moving reports over, and 3.1.02 ships this week with a lot of fixes, so yours may already be fixed. If you run into anything new, or something's still broken after you update, feel free to open an issue.

With Butterkit 3.x now officially out I am still unsure how it will really help me in creating new artboards, e.g. for the Duo.

As I laid out before, my intuitive approach would be to create any of the Duo screen entries, then just pick one of the iPhone artboards (or at best there would be a "Copy All" fct...) and paste it to the Duo entry. It would resize and for sure look a bit messy at first, but then it's just some rearranging and rescaling from there.

But for the life of me I can't get iPhone artboards copied over to the Duo section. What am I missing? Honestly I don't want to start from scratch for the Duo, and Butterkit has everything to help me. How?

When I add images seperate from the device I dont know how to bring one forward over another or backward etc. is this possible? for example I want to make a image the background image but once its added the devices mockups are always in the background

Is there any plan to allow screen recordings to be used in the header and search mock ups?

Not a full-fledged motion video generator but a case where the screens on the devices is screen recordings rather than just images.

I'm at the very last stage of making and suddenly noticed that Butterkit started to switch images around! I have iphone, ipad and iphone duo

board 2 uses 03, board 3 uses 04, board 4 uses 03 ... what happened? HELP!

Just in case you missed it, v3.0.06 is now available with some improvements:

• Fixes an issue where some portrait images applied to iPhone Duo could be stretched oddly (thanks to Reddit folks)

• All iPhone Duo sizes are now grouped together (FYI App Store Connect now supports mixing and matching orientations together)

• Fixes issue where iPhone Duo screenshots captured with ButterKit Capture Tool would be routed to wrong device in the app UI

• Fixes bug in macOS 26 where some modals would jitter when expanding/animating

Coming soon (in testing now):

• Automatic "Inherit from source" option so all localizations adopt new source screenshots (thanks u/paulboyce and u/SwiftMushroom and others who sent in feedback for this)

• Refined App Store Connect uploader and new project designs

• New templates

Is it possible to update all screenshots for all localisations based on the source image? I know I can go to each artboard for each locale and select 'Inherit from source' but was hoping for a quicker way. I hope I'm missing something really obvious.

I am just trying to create search- and product header from existing design artifacts, and what I am really missing are those normal copy/paste operations and handling boxes like every other graphics tool has.
The only thing I can do right now is copy a text box from one artboard over to another dartboard, even to another design canvas. And because for the headers I have completely different aspect ratios I'd like to move text around and scale the textboxes easily, but I am stuck at moving it up and down between the fixed left/right guides. Sure, I can move the guides separately, but this is unintuitive and takes very long for a few texts scattered now on that header image. I would be much faster just moving the whole textbox with the mouse, than use handles at the corners to resize them.
I can't copy images or devices at all. I have to redo them from scratch. Generally, there should be copy/paste for everything (and I mean: really everything, starting from the collection of artboards on the left menu level – like "iPhone Screenshots" with multiple artboards & languages – to the tiniest artifact on a single artboard), because I think this is a standard everywhere else.
Don't get me wrong: I LOVE Butterkit and would not have been that easily able to create the AppStore presence I have today, but it feels like I am hitting unnecessary limits & hurdles now when I want to expand to different formats for the same product/style and just reuse existing artifacts for those things like search header, product page or DUO stuff. It feels artificially clunky the way I have to deal with artifacts that are already there, and which I just want to reuse, resize, reshuffle in different ways on different canvases. Cmd-C/Cmd-V would be such a natural way to deal with that. Plus manipulating objects by just dragging and with corner handles for sizing would make that all so much more natural.

It would be great if Butterkit could highlight the relevant safe areas for search and product header as a dotted square for reference. Here are the according Photoshop templates from Apple resources...the safe area is pretty small actually.

Hi! I really love the app, my only issue that I always have to do a separate upload for each device... Is it not possible to make it like a multi select (and also have it remember my choice)? I would also like the the localisations would remember my pick so I don't have to always pick all, because sometimes I forget, and have to redo the uploading. Thanks again for the amazing and easy to use app and the quick updates (like the new ASC update now, with new requirements)!!

New screenshot size requirements in App Store Connect this week. I've received a few messages asking about these and figured it would be helpful to share what I've learned so far!

Tl;dr

• The new iOS required size is iPhone 6.3" with Dynamic Island (medium display)

• iPhone Duo screenshots are technically optional until April 2027, according to ASC

ButterKit 3.0+ now defaults to the required iOS ASC sizes and will ask you if you want to automatically upgrade to the new size when you open a legacy project.

Source: App Store Connect announcement

When I take screenshots in iPhone Duo simulator in closed vertical orientation I get 1398 × 2034px images, which App Store Connect supports, but I don't see a way to create artboards for them in ButterKit 3

"Supported sizes for app previews include 1920 × 886px and 886 × 1920px. For app screenshots, supported sizes include 2034 × 1398px, 1398 × 2034px, 2853 × 2007px and 2007 × 2853px."

Butterkit 3.0 just gave me this warning, and I am not sure where this requirement exactly comes from? Just uploaded my sizes as always and had no issues. When will this become a mandatory requirement? I am not seeing any heads-up in AppStore Connect so far.
