Suppose my app's Ready for sale version is - 1.0.13. Then an issue came to this version. I've fixed it from Xcode. Everything is fine. Now how'll I update these changes in "Ready for Sale" version? I used to do it in the following way - Archive from xcode Distribute to Testflight Create new version in app store connect select the build Submit for review But these process took so much time. Are there any shortcut so that the changes can be reflected instantly?? Or this is the only procedure to update the app? Suggestions are welcome...
