reload mmpk file internal error

Question

I'm trying to keep the latest updated version of the mmpk file to my iOS app. Loading for the first time of that mmpk file is fine. After downloading the mmpk file using the network request and try to load the mmpk file, it fails and gives back an internal error. That happens only when the new mmpk with different size. Any suggestion or solution for this internal error message?

Previously, I thought it's the file incomplete issue, but it seems that is a memory problem.The below code is the popups are contained popups item and even I call dismiss to close up the popup window and reload the file, it throws an internal error. But if the popups are an empty array the mmpk file reloads successfully. Also, I try to call the clearAllPopups() to clean up the popups the app is crash. Any idea why the self?.popupsVC = nil is not working?

self?.popupsVC = AGSPopupsViewController(popups:popups, containerStyle: .navigationBar)

I found the issue, The file is not 100% download during the download process, that might cause the app gives an internal error. Thanks for your help.

Thanks, Divesh. The app has a checkForUpdate function to check for file update every 5 minutes, if there is a newer version, then I'm trying to delete the old file and replacing it with the new MMPK file. then load it into the map view. But I got an internal error message whenever the new MMPK is smaller than the older file.Is that a memory allocation issue? I only get an internal error from the load completion function, and I don't know what exactly is that mean.
