I downloaded the xcode from web and installed after that i cant find any update regarding xcode on App Store. How to make the app store show updates about the xcode in app store.
Usually even after I update the MacOS to latest it still doesn't show the Xcode update in app store when in Update section. So what worked for me was pressing the "Reload Page" button in the Store in the toolbar menu. Make sure you're in the update section and you'll suddenly see xcode with update button pop up there. See image below.
If you manually downloaded Xcode from https://developer.apple.com/downloads/, then the App Store app isn't aware that there's an Xcode that needs to be automatically updated. The App Store app only keeps track of store apps it downloaded and installed itself.
You need to either download Xcode from the Mac App Store directly or you need to keep watching the http://developer.apple.com/xcode page to get informed of updates.
