Awesome iOS for Agents

Name: awesome-ios-for-agents
Author: jeffy-w

Pick iOS open-source libraries by data, for people and for AI coding agents.

Every library shows the same facts: stars, latest release, last commit, minimum iOS and Swift tools version. The top pick in each category comes from a fixed rule. Data refreshed 2026-11-04 and every week by GitHub Actions.

For agents

Install the ios-starter skill, then ask your agent to start a new iOS app. It asks what the app needs, picks libraries from this catalog by the rule below, creates the project with a verified recipe, and builds and launches it in the Simulator.

Agents can also read the data directly: catalog.json · llms.txt

How the top pick is chosen

Status is based on releases: the date of the latest GitHub release. Only repos that have never published a GitHub release use their last commit date instead. Both dates are shown in the tables.
Status: 🟢 active (< 1 year) · 🟡 slowing (1–2 years) · ⚪ inactive (≥ 2 years) · 🗄 archived.
🏆 Top pick = the most-starred 🟢/🟡 entry in its category. Add-ons of another entry are not ranked. Categories of provider SDKs (backend, payments, analytics, crash reporting, sign-in) are not ranked: pick by service.
Min iOS and Swift tools come from Package.swift at the latest release tag (or the highest version tag when the release tag is not a version number; otherwise the default branch).
Apple native lists the system API for the same job and its minimum OS.
Categories and descriptions are written by hand and only say what a project does. Notes quote a source. Status and rank are computed by scripts/build.py.

Start a new project

Four ways an agent can create an iOS app from nothing. Each was run end to end on Xcode 27.2 on 2026-11-03.

Recipe	Project defined in	Add a package	Verified
XcodeGen	`project.yml`	`packages:` in YAML	create, add package, build, launch
Tuist	`Project.swift`	`Tuist/Package.swift` + `tuist install`	create, add package, build, launch
MobileBuildMCP	Xcode project + local Swift package	local `Package.swift`	create, add package, build, launch
Xcode MCP	Apple's Xcode template	in Xcode (no MCP tool in 27.2)	create, build, launch
