How to Resign an iOS App

Let's say you receive an app (e.g. MyApp.ipa) from another developer, and you want to be able to install and run it on your devices (by using ideviceinstaller, for example).

Or your certificates and provision profiles have expired and you want to provide a new build to your clients without having to make a new build on the latest XCode or iOS SDK.

Prepare New Signing Assets

The first step is to attain a Provisioning Profile which includes all of the devices you wish to install and run on. Ensure that the profile contains a certificate that you have installed in your Keychain Access (e.g. iPhone Developer: Some Body (XXXXXXXXXX) ). Download the profile (MyProfile.mobileprovision) so you can replace the profile embedded in the app.
