Says SwiftLM Not Installed

[brianmrobertson]

It keeps telling me that SwiftLM isn't installed, and I'm not sure how to fix it. I have tried following all hte GitHub instructions without any success.

Hi @brianmrobertson, thanks for the report! To help narrow this down, could you share a bit more detail:

1. OS and hardware — macOS version and chip (Apple Silicon M1/M2/M3/M4, or Intel)?
2. What you're running — are you using the SharpAI Aegis desktop app, or a manual/CLI setup?
3. Exact error — the precise error message/text (or a screenshot) of where it says SwiftLM isn't installed?
4. Steps taken so far — which install instructions you followed, and at what step this message appears?
5. Logs — if you're using Aegis, any logs from its install/setup step would help a lot.

SwiftLM currently targets Apple Silicon Macs, so if you're on an Intel Mac or a different OS, that would explain it. It's also possible this is a macOS Gatekeeper/permissions issue blocking the downloaded binary from running — let us know your setup and we can pin it down.

Thanks for the report, Brian — sorry for the trouble.

Two things:

1. The screenshot and log you mentioned in your email reply didn't make it into this thread (email replies to GitHub notifications strip attachments) — could you attach them directly here on the issue page instead? Click "Add your comment" at the bottom of Says SwiftLM Not Installed #207 and drag the screenshot/log file in (or paste the log text in a code block). Without the actual error text we can't pin down which specific check is failing.

2. In the meantime: you're on an Apple Silicon Mac (M1 Pro) on macOS Tahoe 26.6.2, using the Aegis desktop app — that's a fully supported configuration, so this isn't a "your hardware/OS isn't supported" message, it's something specific to your install that we need the log to diagnose. A couple of things worth trying while we wait on the log:

   • Fully quit the Aegis app (not just close the window) and relaunch it — the install-status check runs at startup, and a stale check from an earlier session can sometimes report the old state.
   • If you have Settings → AI Engine open, check whether it shows different status in different places (an install badge vs. a running-status indicator) — if so, a screenshot of that screen specifically would help.

We'll dig further as soon as we have the actual log text.

I have tried completely closing the app and restarting it.

I don’t think I see different statuses in different places.

I sent the logs and screenshot yesterday. Just let me know if you need anything else to help troubleshoot.

Thank you for your help.

[solderzzc]

Thanks for your patience, Brian, and for confirming you've already tried a full quit/restart.

Update on our end: we dug into the app's own code and found a real gap — right now, when the SwiftLM install fails, the app doesn't actually capture or show WHY it failed (network issue, a corrupted download, a disk problem, etc.) — it just shows the generic "Binary installation failed" message you saw. That's a real bug we're fixing on our side regardless of your specific case, but it also means we can't yet tell from your screenshot/log alone what actually went wrong — the log you sent was for a different component (the Llama Server), not the SwiftLM install attempt itself.

Two things that would help narrow it down while we get that fix in:

1. Could you click the INSTALL button on the SwiftLM card one more time and let us know what happens — does it succeed this time, fail the same way, or show anything different?
2. Roughly how much free disk space does your Mac have? (Settings → General → Storage) — a failed extraction from low disk space is one plausible cause.

Sorry this is taking a few rounds — we want to actually fix the root cause for you, not just guess.

[brianmrobertson]

1. When I click INSTALL again, it just gives me the Binary Installation Failed message.
2. I have 101GB of free disk space.

I have also tried the following in Terminal:

• Clone the repository with recursive submodules: git clone --recursive https://github.com/SharpAI/SwiftLMMove into the project
• directory: cd SwiftLM
• Run the build script to compile Metal kernels and the binary: ./build.sh
• Here is everything that was produced in termina from these commands. Not sure if it will help at all.

Really appreciate the extra effort here, Brian — that manual build is genuinely useful, even though it doesn't directly explain the app's error. Two things from it:

1. Your build actually succeeded ("Build complete!", produced both the SwiftLM binary and mlx.metallib) — the failure you hit after that was just at runtime, when running the binary directly from .build/release/SwiftLM, it couldn't find mlx.metallib because that file landed in a different build output folder (.build/arm64-apple-macosx/release/) than the binary itself. That's a path issue specific to running a manual build directly, not a sign anything's broken on your machine — this at least confirms your Xcode/build toolchain itself is fine.
2. Unfortunately this doesn't tell us why the Aegis app's own download-based install is failing — that's a completely different path (Aegis downloads a pre-built binary+metallib pair as a matched archive, it doesn't compile from source), so the two failures aren't the same mechanism.

Honest status: with 101GB free (ruling out disk space) and a full quit/restart already tried, we're genuinely out of quick things to check on your end. The real fix is on us — right now the app doesn't capture/report why a SwiftLM install actually fails, so we can't see it even when it happens right in front of us. That fix isn't shipped yet.

One thing NOT worth trying: manually copying your self-built binary into Aegis's expected folder won't work — the app verifies installed binaries against a pinned checksum for security, so a self-built one (different bytes than our official release) would just get rejected the same way, not accepted.

We'll follow up here once the improved error-reporting lands and can actually tell us what's failing on your machine. Sorry this is taking a while — thanks for sticking with it.

How can I clear ALL data from the app? I delete the app and the folder under Application Support, but when I reinstall the app, it remembers all my settings, cameras, etc. I want to delete absolutely everything and start from the beginning, but I can't figure out where the other files are.

Thank you.

[solderzzc]

Good question — there are actually two separate data locations, and the one you're missing is a hidden folder:

1. ~/Library/Application Support/sharpai-aegis — this is what you already deleted (Electron's own app data).
2. ~/.aegis-ai — a hidden folder directly in your home directory (not under Application Support), which is where the app actually stores its real config, cameras, and settings. Since it starts with a dot, Finder won't show it unless you press Cmd+Shift+. (period) to reveal hidden files, or use Terminal.

To fully wipe everything:

rm -rf ~/.aegis-ai
rm -rf ~/Library/Application\ Support/sharpai-aegis

Then reinstall/relaunch and it should be a true clean slate.

Not directly related to your original issue, but if you're already wiping things — this is a good opportunity: after this reset, try the SwiftLM install fresh and let us know if it behaves any differently (same failure, different failure, or works). Not expecting it to fix things, but worth knowing either way.

[solderzzc]

Quick update, Brian — we found and fixed the actual root cause on our end: the app genuinely had no way to capture or report why a SwiftLM install fails (it was always just showing a generic "Binary installation failed" no matter what actually went wrong).

We're building a targeted 0.2.10 version right now with that fix (plus a related one) specifically so we can finally see the real error on your machine. I'll post a download link here once it's ready — should be within the next while. Thanks again for all the detail you've provided, it made tracking this down much faster.

[brianmrobertson]

That is what I was looking for. I appreciate the quick reply.

I did try a fresh install, but I still receive the SwiftLM error. I figured it was worth a shot to see if it changed anything.

That's great news that you were able to get it corrected on your end, and I look forward to receiving the download link for the update so we can hopefully figure out what is causing the SwiftLM installation failure.

Thank you.

[solderzzc]

Brian — here's the 0.2.10 build with the fix:

Download: https://releases.sharpai.org/releases/SharpAI-Aegis-0.2.10-arm64.dmg

This isn't a public release yet (it's a targeted build for your case specifically), so please don't share the link, but it's the same signed app either way.

What changed: we found the actual root cause — a stale hardcoded fallback version in the SwiftLM installer that pointed at a build whose download file had been renamed, causing a 404 on any fresh install (unrelated to your machine specifically — this would have affected any first-time installer). We fixed the underlying resolution logic and verified it end-to-end ourselves before sending this to you.

To test:

1. Quit the current app completely and install this build over it (or do a full data wipe first per the earlier instructions, if you'd like a completely clean test).
2. Go to Settings → AI Engine and click INSTALL on the SwiftLM card.

It should now install successfully. If it doesn't, whatever error message appears should now be a real, specific reason instead of the generic "Binary installation failed" — please share exactly what it says if so.

Thanks again for your patience and all the detail through this — it made finding the real cause possible.

[brianmrobertson]

Yes, it did install successfully and I am not receiving the error anymore.

Do you know why Telegram and Aegis would provide a Fetch error when I try to use it? I thought it might be related to the SwiftLM error earlier, but it didn’t go away once that installed.

[solderzzc]

That's great news on SwiftLM, Brian — glad that one's finally sorted, and thank you for sticking with all the back-and-forth on it.

The Telegram issue is a separate thing (not related to SwiftLM) — it's the notification/messaging integration, not the local model. To help us track it down, could you share a bit more:

1. Exact error text — the precise message you see (screenshot is great if easy).
2. Where it happens — is this when you click "Test" on the Telegram channel in Settings, or when it actually tries to send you a notification?
3. Network setup — are you on a network that uses a VPN or proxy to reach the internet? Telegram's servers are blocked in some regions/networks, and that can look exactly like a generic fetch failure.

While we wait on that, we already found something worth fixing on our side regardless: right now, if the connection to Telegram's servers fails for any reason, the app doesn't capture the actual reason (network unreachable, blocked, bad token, etc.) — it just shows a generic, unhelpful error. We're going to fix that so this kind of thing is diagnosable from the error message itself next time, instead of needing a back-and-forth like this.

Thanks again for all the detail you've given us throughout this thread — it's genuinely made a difference in tracking both issues down.
