Version ( CFBundleShortVersionString) must be in ascending sequential order.The pair ( Version, Build number) must be unique.Whereas the android:versionCode is enforced to be an incrementing-on-release integer.Īs noted in the newly accepted answer, Apple has recently published a Technical Note that details their version and build number scheme:Īpple Technical Note TN2420 - Version Numbers and Build NumbersĪpple Technical Note TN2420, Version Numbers and Build Numbers Summary: string, or as any other type of absolute or relative version identifier.ĭifference between versionName and versionNumber in Android The value is a string so that you can describe the application version as a. The android:versionName can remain the same between releases, upgrade, downgrade, or be any random string rather than something that appears to be a valid 'version number'.Īndroid:versionName - A string value that represents the release version of the application code, as it should be shown to users. The discussion prompting this question is that the public 'version' of an Android app in the Google Play Store does not need to be incremented and is in no way validated. Which version/build numbers are required to be incremented when a new version of the app is uploaded to iTunes Connect and/or released to the App Store?Ĭan either 'version' CFBundleShortVersionString or 'build' CFBundleVersion remain the same between app updates?Įxtra points for Apple sources or the exact error messages iTunesConnect displays upon uploading an invalid version/build number. 'iTunes Connect Version Number': version number you specify when creating a new version of the app on iTunes Connect. Leading zeros are truncated from each integer and will be ignored (that is, 1.02.3 is equivalent to 1.2.3). The string should only contain numeric (0-9) and period (.) characters. The build version number should be a string comprised of three non-negative, period-separated integers with the first integer being greater than zero. 'Build' CFBundleVersion (String - iOS, OS X) specifies the build version number of the bundle, which identifies an iteration (released or unreleased) of the bundle. The release version number is a string comprised of three period-separated integers. 'Version' CFBundleShortVersionString (String - iOS, OS X) specifies the release version number of the bundle, which identifies a released iteration of the app.

Version/build fields for an iOS app include:
