Can I Update an Existing App Store App?

Solar2D General Questions/Discussion
#1

I have an app on the app store that uses an sqlite database that stores the users own data. This app was written a couple of years ago using objective-c and Xcode.

Two questions…

Can I rewrite this app using Corona and upload it to the app store as an update of the existing app and if I can then how do I do that?

It’s REALLY important that the users existing sqlite data is NOT overwritten or deleted or replaced so would I have to take any steps to ensure that their sqlite database isn’t altered when the existing app is updated with the new Corona version?

Hey Roddy,

I believe that so long as the app is using the same provisioning profile (as you would do for an update) then it should be fine, however you could test this by installing over the other app on your phone and then checking that database was intact. It’s my understanding if the app is overwritten any databases created by the app shouldn’t be affected. [import]uid: 52491 topic_id: 27883 reply_id: 112863[/import]

Thanks Peach… and I appreciate your prompt reply!

In your experience would I have to set up anything special in the build settings file? [import]uid: 155135 topic_id: 27883 reply_id: 112879[/import]

No worries :slight_smile:

No, you shouldn’t have to modify any code - all your saved files should survive an update AFAIK, although like I said it would be a good idea to run a quick test of this before actually updating the app on the store to be safe. [import]uid: 52491 topic_id: 27883 reply_id: 112933[/import]
