How to Fix Aider Not Editing Files or Failing to Commit in Your Repo

When Aider won't apply edits or commit changes to your iOS repo, the cause is usually git state, file scoping, or a dirty working tree. Here's how to fix it.

The Symptom

You ask Aider to change your Swift code, but nothing seems to happen. Either no files are edited, or the edit is described but never committed.

Sometimes Aider reports that it is not in a git repository, or it refuses to proceed because of uncommitted changes. Other times it edits a file you did not intend.

These problems trace back to how Aider interacts with git and which files you have added to the session. They are configuration and workflow issues, not model failures.

Let's walk through the common causes and their fixes so Aider reliably lands changes in your repo.

Cause 1: You're Not in a Git Repository

Aider is built around git. If you launch it in a directory that is not a git repo, it cannot commit and may refuse to edit safely.

Confirm you are in the root of your project and that a .git directory exists. If your iOS project was never initialized as a repo, initialize one first.

Running Aider from a subfolder that is outside the repo can also confuse it. Launch from the repository root that contains your Xcode project.

Once Aider recognizes a valid git repo, its commit-on-change behavior can work as designed.

Cause 2: The Target Files Aren't Added

Aider only edits files you have explicitly added to the chat session. If you ask for a change but never added the relevant Swift file, it has nothing to edit.

Add the specific files involved before making your request. Aider's repo map gives the model awareness of other files, but edits happen on added files.

If Aider edits the wrong file, it usually means the right one was not added or a similarly named file was. Check exactly which files are in the session.

Scoping the correct files is the fix for most no-edit and wrong-edit situations.

Cause 3: A Dirty or Conflicted Working Tree

If your working tree has uncommitted changes or a merge conflict, Aider's automatic commits can be blocked or behave unexpectedly. It wants a clean state to commit cleanly.

Commit or stash your pending changes before running Aider. Starting clean makes each AI change a distinct, revertible commit.

Resolve any in-progress merges or rebases first. Aider cannot commit sensibly on top of an unresolved conflict.

A clean working tree is the single most reliable way to keep Aider's git integration smooth.

Cause 4: Git Identity or Permissions Not Configured

Git needs a configured user name and email to create commits. If these are missing, commits can fail, which stops Aider from finalizing a change.

Set your git user name and email globally or for the repo. This is standard git setup that Aider relies on.

File permission problems can also block edits. If files are read-only or owned by another user, Aider cannot write to them.

Fix ownership and permissions so your user can write to the project files, then retry.

Cause 5: The Change Was Rejected or Reverted

Sometimes Aider proposes an edit that does not apply cleanly, or you decline it. In those cases no commit lands, which can look like nothing happened.

Read Aider's output carefully. It usually reports whether an edit was applied, skipped, or failed to match the file.

Edits can fail to apply if the file changed underneath Aider, for example if Xcode reformatted it. Re-add the current version of the file and try again.

If you accidentally reverted a change, remember it is recoverable through git history. Nothing is truly lost in a git-backed workflow.

How to Verify the Fix

After addressing the cause, make a tiny test request, such as adding a comment to one added Swift file. Confirm the file changes and that a new git commit appears.

Inspect the commit with your normal git tools to see exactly what changed. Aider's transparency makes verification easy.

Then open Xcode and build to make sure the edited Swift still compiles. Landing a commit is only half the job; the code must also be correct.

Once a small edit works end to end, resume your normal, larger tasks with confidence.

Prevention Tips

Always start Aider from your repository root with a clean working tree. This prevents most git-related friction before it starts.

Work on a feature branch so AI edits are isolated and easy to discard or squash later. It keeps your main branch safe.

Add exactly the files you intend to change, and check the session's file list before prompting. Precise scoping prevents wrong-file edits.

Keep in mind the boundary of the tool. Aider handles editing and committing Swift, while building and shipping the iOS app remain Xcode's job on a Mac.

Understanding Aider's Edit-and-Commit Loop

Many of these problems make more sense once you picture what Aider is actually doing under the hood. It reads the files you added, asks the model for a change, applies the resulting edit to your working tree, and then commits that edit to git with a generated message.

Each link in that chain can fail independently. If the file was not added, there is nothing to edit. If the edit does not match the current file contents, it cannot be applied. If git has no identity or the tree is conflicted, the commit cannot be created even when the edit succeeded.

Seeing the loop this way turns vague trouble into a checklist. Was the file in the session, did the edit apply, and did the commit land? Answering those three questions in order almost always pinpoints the break.

It also explains why a clean tree and a feature branch help so much. They remove ambiguity from the commit step, so the only thing left to reason about is whether the model produced a sensible edit, which you then confirm by building in Xcode.

Handling the Xcode-Aider File Conflict

A subtle source of trouble is that two tools are touching the same files. Xcode may reformat, re-indent, or rewrite a Swift file at the same time you are editing it through Aider, and that can cause edits to fail to apply.

When an edit does not match, it usually means the on-disk file differs from what Aider last saw. The fix is simple: re-add the current version of the file to the session so the model works against the real contents, then reissue your request.

To reduce these collisions, try to let one tool settle before the other acts. Save and let Xcode finish any automatic formatting before asking Aider for changes, and pull Aider's committed changes into your Xcode view before continuing.

Generated project files add another wrinkle. The .xcodeproj can change in ways that are noisy in git, so keep an eye on what gets committed and avoid asking Aider to hand-edit project metadata it does not understand. Let Xcode own the project file, and let Aider own the Swift source. Keeping those responsibilities separate prevents most of the friction between the two tools.

Frequently Asked Questions

Why won't Aider edit my Swift file?

Most often the file was not added to the Aider session. Add the specific file before prompting, since Aider only edits files you have explicitly added.

Aider says it's not in a git repository. What do I do?

Launch Aider from your project's git root, and make sure the project is actually initialized as a git repo. Aider needs git to commit its changes.

Why do Aider's commits fail?

Common causes are a missing git user name and email, a dirty or conflicted working tree, or file permission problems. Configure git identity, clean the tree, and ensure you can write to the files.

Can I recover a change Aider reverted?

Yes. Because every change goes through git, you can recover it from your git history using standard git commands.
