Hello Kim,
Certainly AB do not full document the Cordova / iOS / General and Signing options. But they can be deduced from the iOS and Apple "worlds", to say like that.
So you need to search for information about what a "Bundle version", means in the Apple "world", as well what is the "App ID", the "Deployment target" and the "Target device". Here are examples for these fields:
The above is for the General options. The signing options are the same, that is, refers to things that we need and are more or less common in the Apple development world: "Code sign identity", "Development team", "Package type" and "Build blags".
The Signing options refers to things that you must have available in your Apple Developer account. So, for example, you must have created a "Code sign identity", and that is what you must place in the "Code sign identity" field.
The same for the other options: you must have one or more "Development teams" in your Apple Developer account, so you must place in the "Development team" field one of the availables. The "Package type" refers also to options provided by Apple: probably in your case you must choose the "app-store" value for this option.
The "Build flags" can contain... specific build flags to take in consideration when compile our apps in XCode. In principle you no need to fill this field, if you no need to use specific build flags. Below you can see a sample of build flags that we can use:
I hope this information can help you in some way. I must admit that there are not very well documented in App Builder, however, these options refers to Apple and iOS things, so they can be found documented in the Apple Developer website, we can find the right values from our Apple Developer account, etc.
Anyway, please, go ahead if you have any other specific question and we will try to help you.
