iOS App Signer

iOS App Signer is a macOS utility that takes existing iOS, tvOS or Apple TV application bundles—such as ipa, deb, app or xcarchive files—and re‑signs them with a provided developer certificate and provisioning profile, producing a new ipa ready for installation on a device. The tool handles the signing process and repackaging, allowing users to prepare apps for deployment without rebuilding from source.

The application is intended for developers or power users who have a paid Apple developer account, a signing certificate and a provisioning profile, and who need to install custom or modified apps on iOS or tvOS devices via a physical cable. It works on macOS 10.9 or later with Xcode 7 or newer, and it integrates with Xcode’s device management to load the signed bundle onto a connected device.

What distinguishes iOS App Signer is its support for multiple input formats and its straightforward graphical workflow: select the source bundle, choose the signing credentials, and start the process to generate an installable ipa. The project builds on earlier work from iReSign and provides a stable, macOS‑only solution for app re‑signing and bundling.
