pushback

From the gate to the App Store, in one command. Ship an iOS app to TestFlight from your laptop — no CI, no Ruby, no Fastlane setup tax.

pushback            # auto-detects: open PR → merge & ship, else ship current branch
pushback --dry-run  # rehearse the whole thing — no merge, no upload, no push

pushback is a single, dependency-light bash script that does the entire release in one pass:

verify build → QA gate → (merge PR) → bump version → archive → upload → commit & push.

The name is the joke and the spec: in aviation, pushback is the tug easing the plane off the gate — the first move of departure. And it's what you do to ship: git push, then watch it go.

Why not Fastlane?

Fastlane is great — for teams of three sharing certificates (match), for automating App Store metadata and screenshots, and for running inside CI. If that's you, use Fastlane.

pushback is for the other case: one app, one person, shipping from a laptop, no CI. There, Fastlane is mostly setup tax for features you don't use, and you still end up writing glue for the parts it doesn't cover — like merging the right PR or running a smoke test before main is touched. pushback is that glue, made first-class:

• PR-aware. Detects the open PR for your branch, checks your local HEAD matches it, and verifies the build before the squash-merge — a broken iOS build can't land in main.
• Ships from main too. No PR? Already merged? It ships the current branch's actual state, including uncommitted changes if you want.
• Pre-merge QA gate. Unit/snapshot tests, plus Maestro smoke flows if installed, before anything irreversible happens.
• Smart rollback. Knows the one thing you must never do — revert a build number after the upload burned it in App Store Connect — and never does it.
• One command. Laptop → TestFlight, no context-switch to a CI dashboard.

It deliberately does not try to be Fastlane. It drives xcodebuild, git, gh, and xcodegen directly. iOS-focused today; the merge → bump → ship skeleton would extend to other targets, but pushback doesn't pretend to be multi-platform until it is.

Install

curl -fsSL https://raw.githubusercontent.com/tshiv/pushback/main/install.sh | bash

Or grab the one file and put it on your PATH:

curl -fsSL https://raw.githubusercontent.com/tshiv/pushback/main/pushback -o /usr/local/bin/pushback
chmod +x /usr/local/bin/pushback

Requires: git, gh, xcodegen, Xcode (real xcodebuild, not Command Line Tools), and an App Store Connect API key.

Optional, auto-detected, gracefully skipped if missing:

• xcbeautify — prettier build output (brew install xcbeautify)
• maestro — UI smoke flows in the QA gate

Set up an App Store Connect API key (App Store Connect → Users and Access → Integrations → Keys), download the .p8, and place it at ~/.private_keys/AuthKey_<KEYID>.p8. Put the key id + issuer id in .env.local (or export them):

APPSTORE_CONNECT_API_KEY_ID=XXXXXXXXXX
APPSTORE_CONNECT_API_ISSUER_ID=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx

Your ExportOptions.plist must set destination=upload so the single -exportArchive step both packages and uploads (no altool follow-up).

Setup

Copy the sample config to your project and edit it:

curl -fsSL https://raw.githubusercontent.com/tshiv/pushback/main/.pushbackrc.example -o ios/.pushbackrc

.pushbackrc is sourced shell (no YAML parser needed). In most projects you only need PUSHBACK_SCHEME; everything else derives from it or has a default:

PUSHBACK_PRODUCT_NAME="my app"
PUSHBACK_APP_DIR="ios"
PUSHBACK_SCHEME="MyApp"

Then run it (point --config at your .pushbackrc, or drop a .pushbackrc next to the binary / in the working directory):

pushback --config ios/.pushbackrc --dry-run

A common pattern is a tiny wrapper script checked into your repo:

#!/bin/bash
set -euo pipefail
DIR="$(cd "$(dirname "$0")" && pwd)"
exec pushback --config "$DIR/.pushbackrc" "$@"

Usage

pushback [options] [PR_NUMBER]

Invocation	What happens
pushback	Auto-detect. Open PR for the branch → PR mode. Else → from-main mode.
pushback 37	Merge + ship PR #37.
pushback --from-main	Force from-main mode (ignore any PR). Alias: --no-merge.
pushback --dry-run	Run everything reversible; stub merge, archive, upload, push; revert the bump.
pushback --skip-qa	Skip the unit-test + Maestro gate.
pushback --yes	Don't prompt. A dirty tree is included wholesale.
pushback --config <path>	Point at a specific .pushbackrc (default: ./.pushbackrc).

Modes

PR mode — there's an open PR for the current branch (or you passed a PR number). pushback verifies the build on the PR branch, runs QA, squash-merges, pulls main, then ships. Requires a clean working tree (you're shipping the PR's code).

From-main mode — no open PR; you're on main (already merged) or a local branch. pushback ships the current branch's current state and pushes the version bump to that branch. If the tree is dirty it asks what to do:

Ship these changes?
  i  include them in the version-bump commit and ship
  s  stash them, ship committed HEAD only, restore after
  d  show full diff
  a  abort

include folds your uncommitted work into the bump commit (the build already reads your working tree, so this is literally "ship what I see"). stash ships only committed HEAD and restores your changes afterward — and never drops the stash on a conflict.

Both modes show a one-line summary and ask for confirmation before the irreversible archive+upload. --yes skips the prompts.

The build-number invariant

Once -exportArchive succeeds, the bumped build number is burned in App Store Connect — reusing it fails validation. So pushback's failure handler:

• reverts the bump if it failed before the upload,
• leaves the bump in place and tells you to commit manually if the upload succeeded but the commit/push failed,
• tells you to just push if the commit landed but the push failed.

It never reverts a burned build number.

Configuration

.pushbackrc is sourced shell. See .pushbackrc.example for every key. Minimal config needs only PUSHBACK_SCHEME; everything else derives from it or has a default.
