Does Apple optimize (make faster) an app when it is uploaded to the app store?
Does Apple optimize (make faster) an app when it is uploaded to the app store? I believe I had heard or read somewhere after you submit your app to the app store it is made much faster. Is this true?
No... they don't touch your code so there's no way this happens. It might be that locally, on an emulator, or with debugging options on, it feels slower, so when you finally upload it, it's 'faster'.
ok thanks
There are optimisations made to what is packaged when the app is downloaded on a given iOS version. For instance, if you make an app that works across iOS 5-11 and the download is eg 500MB, downloading on iOS11 may only need 100MB because Apple as removed the code required for backwards compatibility with iOS 5-10.
