How to re-sign an iOS app with another developer account

Raw

gistfile1.md

To re-sign an iOS app with another developer account, ensure that the following are in place first.

Distribution certificate of the other developer account
A provisioning profile from the other developer account

Note that the Apple requires bundle IDs to be globally unique. So if you have an app with bundle id "com.example.app" from a dev account, you can't re-use the same bundle ID in another dev account (even though the team id/prefix would be different).

Ensure that the new distribution certificate is in your keychain and the new provisioning profile on your disk.

Unzip the .ipa. This will usually unzip to Payload/<app-name>.app/
Export the entitlements.plist from the app

This didn't work for me, I tried to submit the resigned app with another distro cert/profile and it complained about the app needed to be signed with the original profile.

If you're still having troubles with codesigning your iOS app, I strongly recommend you to check out AirSignApp (https://www.airsignapp.com).

I've followed these excellent steps and am close but I'm getting the error "mapped file does not the same team identifier as main process" for my frameworks Alamofire, etc. Looking closer I can see that have the old identifier. How do I change the frameworks to have the same identifier ?

Duraiamuthan commented Jun 28, 2016

Framework has to be signed along with the app if you are going to use different signer

codesign -f -s "Distribution Certificate Name" .app/Frameworks/*

then sign the app again

codesign -f -s "Distribution Certificate Name" .app

When resigning app by changing it's bundle ID the services which we have been registered using the bundleID like notification services won't work anymore. Is there anyway to resign the application with another account without changing provision profile?

irodkin commented Nov 1, 2017

@niloufarMakhzani You can use 'codesign -s' command without specifying '-i' option. (Execute 'codesign --help' for details.)

Great list.

any suggestions for Step 7, now that PackageApplication has been deprecated for 1y + ?

Blackjacx commented Apr 24, 2020

Can I resign a distribution signed IPA with a development certificate? My app crashe constantly at launch time. I don't get it...

Step 7 can be skipped (at least since PackageApplication is deprecated), just zip up your Payload folder:
zip -r /path/to/new.ipa /path/to/Payload

I successfully re signed an IPA file following the steps above. The IPA file can be downloaded after being placed on my server. But it cannot be opened after the download is completed

As for the most of iOS errors, it's almost impossible to figure out the actual reason from its message. You should observe device logs at the moment when installation is finished or when you first try to run the app.
