Sketch "Browse All Versions" restore: no reliable way to confirm what was actually recovered

Question

After using Sketch's native macOS version history (File > Revert To > Browse All Versions) to roll a .sketch document back to an earlier state, there is no built-in report showing what changed between the restored version and the one it replaced. The goal is a dependable way to verify that a restored document actually contains the expected pages, artboards, symbol sources, and linked libraries before continuing work on it.

The constraints make this harder than it sounds. Versions are captured on explicit saves and at automatic checkpoints whose triggers are not clearly documented, so the nearest restorable point may predate the work I actually need. Restoring also replaces the current state outright, and files stored in iCloud Drive or moved between machines may carry incomplete version metadata, so the available timeline itself is uncertain.

Assuming a recent Sketch release on a current macOS version:

Is there any documented way to compare two versions (or diff the restored document against its pre-restore state) rather than checking pages and symbols manually?
Which events trigger automatic version snapshots, so a predictable recovery interval can be planned around?
Does restore behavior differ for documents managed through Sketch Workspace versus plain local files?

Answer the core question first
Sketch does not ship a UI for comparing two document versions or for reporting what changed after a Browse All Versions restore. The only documented way to confirm that the file now contains the pages, artboards, symbols and libraries you expect is to inspect the restored file manually, or to export it for side‑by‑side comparison.
Why there is no internal diff

Sketch’s version history is a snapshot of the entire .sketch binary, not a line‑by‑line change log.
The app replaces the current file atomically; it does not keep a side‑by‑side diff view.

How to reliably verify a restore

Make a pre‑restore copy

Before you click Browse All Versions, duplicate the file (e.g., File → Duplicate or copy the file in Finder). This preserves the exact binary you are about to replace.

Perform the restore

Use File → Revert To → Browse All Versions and pick the desired point in time.

Export both versions

Open the original copy and export it as PDF (or SVG). Do the same for the restored file.
Exporting forces Sketch to resolve all symbols, artboards, and linked libraries into a single raster or vector document, making visual comparison straightforward.

Compare the exports

Use a visual diff tool (e.g., Kaleidoscope, Beyond Compare, or a command‑line diff -u on the PDF byte streams).
For a quick binary check, run cmp restored.sketch original.sketch or xxd -C restored.sketch | diff -u - original.sketch to spot any binary differences.

Verify metadata

Run mdls restored.sketch and check kMDItemFSContentChangeDate to confirm the file’s last modification time matches the expected restore point.

Cross‑check with backups

If you use Time Machine or another local backup, restore the file from the backup that corresponds to the pre‑restore state and compare it to the restored file as above.

Automatic snapshot triggers
Sketch creates snapshots in three situations (as understood from recent releases):

Explicit Save actions.
After a crash or an unexpected quit—Sketch re‑creates the file on relaunch.
Periodic checkpoints during active editing, roughly every 5 minutes, though the exact interval is not formally documented.

Workspace vs. plain local files
When a file lives inside a Sketch Workspace:

The restore operation still replaces the local copy atomically.
After the restore, the Workspace sync engine may re‑push the latest remote changes, potentially overwriting your restored state if the remote version is newer. Disable Workspace sync temporarily to avoid this race.

What to ask for a more precise recommendation
To fine‑tune the steps above, it would help to know:

The exact Sketch version you are running (e.g., 70.0.2).
The macOS release (e.g., Ventura 13.4).
Whether the file is stored in iCloud, a local folder, or a Workspace.

With that information, you can confirm the snapshot interval and the exact restore behavior for your environment.
