I have created a very simple bundle library. I am transitioning from a 2018 macbook pro Intel to a 2021 MBP M1 Max. I have the latest xcode installed on both computers. This library just has a single .h and single .mm Obj-C files. I have it set to build both M1 and Intel architectures. When I build this on the Intel mac I can copy my bundle to the M1 mac and use it from the environment that I need it in. When I build the exact same project on my new mac with M1 and try to run it my environment says it can't find the bundle. Is there something I need to know about building on the M1 versus Intel?

Hello Apple Forum friends. We launched an application on app store few years back and its live and running. Now we have created an upgraded version of this app independent to old app's xcode project. We have finished developing our first releasable product and are ready to publish on app store but we do not want to publish it as a separate app, instead we want to publish as an update of old app which is available on app store. These two apps now use different bundle id, so is there any possible way to publish it as an update ?
