Profiling a blank application on iOS 12.2 and later always seems to contain memory leaks. We've detected lots of memory warnings in our public iOS app as well. This seems to be a problem with iOS's core frameworks. I've submitted a bug report for this issue here: https://bugreport.apple.com/web/?problemID=49962169 but no response from Apple. Has anyone else encountered this? Could it be a problem with Instruments?

I think the latest tools are more chatty w/iOS 12.x. If you think those warnings are actionable, however, your best approach might be to burn a ticket w/DTS via the Member Center, being sure to have a buildable project of your store app they can take a look at.
