Xcode 8 shows error that provisioning profile doesn't include signing certificate

There are many ways to fix this, like enabling automatic signing etc. But if you want to understand the reason for this error you need to look at the error message.

It says that the provisioning profile you have selected in the "General tab", does not contain the signing certificate you selected in the "Build settings" -> "Code Signing Identity".

Usually this happens if a distribution certificate has been selected for the debug identity under "Build settings" -> "Code Signing Identity".

If this happens under "Signing (Debug)" it might also be that the "Signing Identity" -> "iOS Development" is not included in the provisioning profile.

Check your keychain for identities that are missing a private key. I had multiple distribution certificates installed for the same team, one of which was missing the private key. Xcode was only checking the first matching identity in the keychain and automatically using this as opposed to the one that did include the private key.

Removing the matching identity that didn't have a private key made Xcode detect the correct identity again.

To fix this,

I just enable the "Automatic manage signing" at project settings general tab, Before enabling that i was afraid that it may have some side effects but once i enable that works for me.

Hope this helps for others!
