Generate abb and ipa without certificates

Hi,
I have to compile ipa and abb files that later will be published under my custom developer account.

He wants to use his own certificates in both Android an iOS, and I assume he doesn’t want to share the private with me.

Is this possible in Android and iOS?
Also, what happens with the mobileprovision…

Thanks

Certificates must be added prior to generating a production build. You could add your own certificates, but your customer would not be able to change them to their own once you send the files along. Your customer will need to provide you with the needed certificates.

The same is true for the mobileprovision. The mobileprovision is required to generate all iOS builds.

Hi,
does this apply for Android too?

In Android, could I use VoltSigner to sign with a selfsigned certificate (o even no signing at all), and then my customer can use Play App Signing later?

Thanks

Debug Android builds don’t require certificates, but production builds do. With Play App Signing, the certificate you sign your app with is the upload key. You will want to provide that to your customer. Once uploaded the app is signed by the play store.

Ok, I understand.
my customer needs his certificate to be used, and they can’t provide it to me.

I assume the only workaround will be to compile my source files with his Xcode + Cordova.

Thanks for your help

Unfortunately yes.
