What is IPA signing?

IPA signing refers to the process of digitally signing an application's IPA file which provides trust and makes the application installable on non-jailbroken iOS devices. It is a critical step for developers, as iOS devices only allow the installation of applications signed with a valid certificate. This guide will walk you through the steps of signing and installing an IPA file.

How to sign an IPA file?

The first step to sign an IPA file is to obtain a valid Apple Developer account. After registering your account, you will need to create a development certificate and a Provisioning Profile. A development certificate enables a developer to sign applications, while a Provisioning Profile contains information about what devices the developer wants to test the application on. Ensure to sign the IPA file with a development certificate that is valid in the Provisioning Profile. The next step is to use a tool like Xcode or a third-party code signing tool to sign the IPA file. Both tools require the selection of the signed certificate and Provisioning Profile of the desired application. After signing, the IPA file will be ready to install on devices.

How to install a signed IPA file?

There are two ways to install a signed IPA file on an iOS device: through Xcode or a third-party software. To install via Xcode, connect the iOS device to the computer and select the "Add Device" option in Xcode. Then choose the "File" menu and select "Devices and Simulators" followed by "Installed Apps" and then click the "+" button in the bottom left corner. Locate the signed IPA file and select the iOS device you wish to install it on. To install via a third-party software, a popular software like Cydia Impactor can be used. Connect the iOS device to the computer, and drag the signed IPA file into the software. Then, enter an Apple ID associated with your Developer account and the installation will start. Once installed, the application is ready to be used.
