An asset catalog is a pile of folders and JSON. Resors turns your colours, images and SF Symbols into a design system you can actually see, change and reuse. Visually, from first import to shipped catalog.
Xcode previews your assets one catalog at a time, inside the project that owns it, at thumbnail size. Resors keeps every colour, symbol and image you have in structured grids and groups, across every project you ship, at a size you can actually judge.
Nothing is converted or migrated. Import your catalogs by drag and drop, from the file browser, or through catalog sync.
A colour four projects share is four separate colour sets, one in each catalog. Changing it means opening four projects, making the same edit four times, and they drift the moment one gets missed. In Resors it is a single asset. Export it into any catalog, or connect a group and let it sync, so one edit reaches every project without a manual pass through Xcode.
Four copies of one decision, with nothing keeping them in step.
Edit once, then export into any catalog or let a connected group sync it out. New assets are created here too, with every appearance and exact values in reach.
A custom SF Symbol is more than artwork. It carries leading and trailing margins and a scale that decide how it sits beside text. Resors edits those against live guides and previews the result. Xcode exposes none of it, and the SF Symbols app sends you back to a vector editor and another export.

Colours land on type, buttons, toggles and the shapes you fill with them. Symbols sit in menu rows, cards and buttons at the weight and scale you ship. Images fill the rows and cards they were made for. A field tells you the value; this tells you whether it works.

Save a set of assets as a group and it becomes the starting point for whatever you build next. No copying folders between repositories, and no slowly drifting duplicates of the same blue.
The system is only useful if it lands in the project. Export assets and groups in one action, straight into the asset catalog. Or set up sync between a group and a catalog, and assets import and export on their own, both directions.
Select one asset or an entire group and write a catalog Xcode reads directly. Appearances, colour spaces and symbol margins all land intact in one pass, with no folder plumbing and no JSON to hand-edit.
A group is paired with one asset catalog and stays paired with it. Sync runs when you launch it, never behind your back, and a single pass covers the lot: whatever landed in Xcode comes in, validated on the way; your edits go out to the catalog; and anything that diverged on both sides is settled by the rule you set. No re-export, no drag and drop, no second copy to keep straight.
Sync will not stop to interrogate you. Set how divergence is settled for a paired group and Resors applies it as the sync runs, asset by asset. Keeping Resors, keeping Xcode and keeping the newest edit all work today. Handing the call back to you, asset by asset, arrives in v1.4.
The most recent edit wins, whichever side made it. Here that is Resors, at 14:22.
Colours, images and SF Symbols from every project in one place, at a size you can actually judge, with system and custom groups down the side.
Every part of an asset is editable in place: its appearances, its exact values, the artwork behind it and the way it renders, with the result on screen as you go.
Sort assets into system and custom groups, and let one asset belong to several. Select a whole run and export, duplicate or change what it belongs to in one go.
Launch a sync on a paired group and it tells you what it did: the assets it moved, how many operations that took and how long it ran.
See an asset on live text, buttons, toggles, shapes and symbols before it reaches your project.
Everything that makes the system is free. Resors+ covers getting it back out to Xcode.
Free on the Mac App Store, and the catalog you already have works the moment you drop it in.
