<li>Remove my account at Xcode / Preferences at the top right.</li>
<li>open keychain. At the left "my certificates": Delete the Mac or iPhone etc Developer certificate.</li>

In my case,

1- Open Keychain Access

2- Select login, and click Certificates 

3- Double click Apple Worldwide Developer Relations Certificate Authority

4- Open trust section, and set to "Use System Defaults" from "Always Trust"

5- Clean build folder and run

I too had the same error <code>unable to build chain to self-signed root for signer...</code>

My mistake was that I had changed the trust setting of my distribution / developer cert to <code>always trust</code>. When I changed it back to <code>Use system Default</code> it all worked.

I saw other answers and attempted to delete my intermediate keychains and root certificate. But Apple doesn't allow to remove Root certs unless you're in recovery mode and I didn't want to try that. Likely you don't have to delete anything either as this solution works without it. 

I just thought I'd add an image to clarify things. I ran into this issue when I was poking around in my Keychain and accidentally changed the default settings. 

<h1>Identifying the bad certificate:</h1>

<ol>
<li>From you Keychains select Login</li>
<li>From Category select Certificates</li>
<li>Find any Apple Certificate that has the blue + like <img src="https://i.imgur.com/7ngEYPA.png" width="12" height="12"></li>
<li>Double click on the certificate. You'll see it look like this</li>
</ol>

</ol>

<h1>Fixing the bad certificate:</h1>

<ol>
<li>Just set it to "Use System Defaults" and close it.</li>
<li>You'll get a pop up. Type in your password to update settings. </li>
<li>Close KeyChain. Go back to your project, clean and run. Problem should have gone away. </li>
<li>If that didn't work then go back to Keychain and just double check and see if there are any other Apple certificates that are set to Always Trust and repeat the process. </li>

After struggling one day with many answer on forum. I came up with solution works for me. below are steps for fix:
<ol>
<li>Download below certificate from apple PKI official site <a href="https://www.apple.com/certificateauthority/" rel="nofollow noreferrer">https://www.apple.com/certificateauthority/</a></li>

 Worldwide Developer Relations - G3 (Expiring 02/20/2030 00:00:00 UTC)
</code></pre>
</blockquote>
<ol start="2">
<li>Download all Certificate and profiles, extension profile specific to your app for development and distribution.</li>
<li>Go to Xcode Preferences menu (command+,) and then Accounts tab. Delete all account</li>
<li>Quit Xcode</li>
<li>Open Key chain and go to login section of Certificate tab</li>
<li>Remove all root and intermediate certificates, Developer ID Certification Authority from key chain.</li>
<li>Remove all your app specific certificate</li>
<li>Open finder, go to location (shift+cmd + g) ~/Library/MobileDevice/Provisioning\ Profiles and remove all certificate</li>
</ol>
<blockquote>
<ol start="9">
<li>Relaunch Keychain and go to login section of Certificate tab</li>
<li>Drag drop root certificates to keychain (root certificate will be trusted automatically do not make it manually )</li>
<li>Drag drop intermediate certificates to keychain</li>
<li>Drag drop app specific certificate (.p12) to keychain</li>
</ol>
</blockquote>
<ol start="13">
<li>Open finder, go to location (shift+cmd + g) ~/Library/MobileDevice/Provisioning\ Profiles and add you app specific profiles. Optionally you can login with apple account in Xcode setting and download manually for each profile.</li>
<li>Open Xcode and clean derive data (Shift+ Alt+ cmd+ k), and build it with any device.</li>
</ol>
This issue happens due to apple has introduced new root certificate and intermediate certificate. Read more detail from <a href="https://developer.apple.com/support/wwdr-intermediate-certificate/" rel="nofollow noreferrer">https://developer.apple.com/support/wwdr-intermediate-certificate/</a>

I'm adding the solution that fixed it for me, and is already on <a href="https://developer.apple.com/forums/thread/86161?page=2" rel="nofollow noreferrer">that thread</a>
The key issue here is the root certificate
Export and delete from login/certificate the certifictes named &quot;Apple Worldwide Developer Relations Certification Authority&quot; in your Keychain.
Do the same from system/certificate.
Import in system/certificate only ONE &quot;Apple Worldwide Developer Relations Certification Authority&quot;. I imported the one that has the expiration date set to 2030 (not 2023).
You can also download the latest from:
<a href="https://www.apple.com/certificateauthority/AppleWWDRCAG3.cer" rel="nofollow noreferrer">https://www.apple.com/certificateauthority/AppleWWDRCAG3.cer</a>
That's all.
But again, make sure it is in your Keychain's SYSTEM and you ONLY have ONE root certificate in your Keychain's SYSTEM area, AND NONE in LOGIN area.

You are using Distribution certificate instead of Development Certificate if you are able to install app in debug mode but it closes automatically once installation completed.

It is also important to note that the physical device you are trying to deploy to must be listed in the allowed devices list for that provisioning profile -> you can see this here in the tooltip that pops up from your cert information -> you want to make sure that your device is listed in the "Devices" section. 

You can add / remove devices when you create the provisioning profile on the apple developer portal website.
