While developed primarily by me, nab138, iloader is only possible because of the large community of open-source developers, contributors, users, and more involved with sideloading. Thank you all!

Technical Details

How iloader works

How iloader works

iloader works by essentially pretending to be a Mac running Xcode, allowing it to use Apple's official APIs and tools for sideloading, which are intended for developers to test their apps.

  1. First, iloader aquires information about a fake Mac from an anisette server. This is why a Mac shows up in your Apple ID devices when you use iloader. If iloader hasn't logged in from this computer before, it provisions with the anisette server to get a new fake Mac identity, called an adi.pb, which can be reused for future logins. This is why you have to log in with 2FA the first time you use iloader, but not subsequent times.
  2. Next, iloader uses this information to log in to your Apple ID using Apple's GrandSlam authentication protocol. This is a multi-step process that uses the Secure Remote Password (SRP) protocol to securely transmit your password and 2FA code to Apple.
  3. Once logged in, iloader aquires a token for Xcode, which it can then use to create a developer session.
  4. When sideloading an app, iloader has to register an app ID and app group, assign the app id to the group, and create a provisioning profile for the app. It does all of this using Apple's APIs, just like Xcode would.
  5. iloader also has to acquire a development certificate to sign the app with. If iloader doesn't have one stored, it has to create a new one and send a certificate signing request (CSR) to Apple and have it signed.
  6. iloader then uses the provisioning profile and certificate to sign the app with apple-codesign, at which point it can be transferred to the device and installed using idevice.
