<h2><a class="anchor" name="reproducible-builds-for-ios" href="#reproducible-builds-for-ios"><i class="anchor-icon"></i></a>Reproducible Builds for iOS</h2>
|
||
<p>The verification process for iOS builds is, unfortunately, a lot more complex than for Android. The two main issues with Apple's current policies and infrastructure are as follows:</p>
|
||
<ol>
|
||
<li><p>Apple insists on using <strong>FairPlay</strong> encryption to “protect” even <strong>free</strong> apps from “app pirates” which makes obtaining the executable code of apps impossible without a jailbroken device. To solve this issue, Apple would simply need to allow submitting unencryptable binaries to the App Store. This would not affect security since the code would still be signed – and would enable anyone to check the integrity of apps supporting reproducible builds without endangering the integrity and security of their devices.</p>
|
||
</li>
|
||
<li><p>Building your own reproducible binaries is difficult because macOS doesn't support containers like Docker. If Apple followed in the footsteps of Linux (and even Microsoft!) and added container support, it would eliminate the need for steps 1-3 in the guide below.</p>
|
||
</li>
|
||
</ol>
|
||
<blockquote>
|
||
<p>As things stand now, you'll need a <strong>jailbroken device</strong>, at least <strong>1,5 hours</strong> and approximately <strong>90GB</strong> of free space to properly set up a virtual machine for the verification process.</p>
|
||
</blockquote>
|
||
<p>To provide a stable and easily reproducible environment, Telegram iOS builds are compiled on a virtual machine. Parallels is used to verify the builds.</p>
|
||
<blockquote>
|
||
<p>Due to recent changes introduced in <strong>XCode 14</strong> by Apple, the instruction below doesn't work at the moment. <strong>We will update this page as soon as Apple resolves the issue.</strong> <a href="#troubleshooting-ios">Read more about the issue</a> </p>

<li><p>You will get a warning if the archive created in <a href="#step-7-building-the-app">Step 7</a> contains encrypted files. If all these files are in the <code>PlugIns</code> subfolder, they represent various system extensions (e.g. external sharing, Siri, 3D touch). Decrypting such files using existing ways of receiving app archives via Jailbreak is non-trivial (but we're working on resolving this issue). If you do manage to decrypt them, e.g. on iOS 8, they will be matched.</p>
|
||
</li>

<li><p>You will be notified if the archive includes an <strong>Apple Watch app</strong>. The watch app will soon no longer be included in the archive.</p>

<li><p>Files with the <code>.car</code> extension are app resource archives (images, sounds) which were compiled and processed specifically for the target device. The App Store processes them in non-trivial ways, we're planning on getting rid of them in future versions.</p>
