I would like to publish a series of Ionic apps that share the same code and differ only for some resources (eg the icon and the background image) and the title. Each of these apps must contain an identifier to download the appropriate data from the Cloud. Is there a way to automate this process or do I have to manually modify the config.xml file, create certificates, deploy, etc.? Apps must be published on both Google Play and iTunes.
Yes, you will have to adjust those elements yourself. Maybe create a batch script to assist.
Note: Apple is cracking down on apps that are clones of one another. Your apps may not have this problem, but something to be aware of.
