MacOS High Sierra : Xcode failed to download Use the purchase page Error during installing Xcode 9.3 Yesterday I update MacOS Sierra to MacOS High Sierra than I remove xCode 9.2 after that when I try to install xCode 9.3 from App Store, It gives me below error:

Xcode failed to download, Use the purchase page to try again
I tried below solutions.

1. Remove Account and again add it.

2. https://gist.github.com/ferbass/3ecc06a8ae992365bf73

3. Xcode failed to download. Use the Purchases page to try again (But There's no Debug menu in MacOS High Sierra)

4. Try to install xCode with Different account but facing same error.

5. Other Applications are downloadable but facing error only in xCode installation.

below are screenshots
I had the same issue and finally got this working, however I'm not sure exactly which step made it work, so I'm posting all of them.

From How to fix / Reset App Store app on Mac OSX - El Capitan:

Delete:

~/Library/Caches/com.apple.appstore
~/Library/Caches/storeaccount
~/Library/Caches/storeassets
~/Library/Caches/storedownload
~/Library/Caches/storeinappd


I didn't have some of those folders, but I did have a couple of extras that looked fishy, so I deleted them too:

~/Library/Caches/storeassetd
~/Library/Caches/storedownloadd


Run sudo softwareupdate --clear-catalog [Note: I did this but I don't think it helped]

From http://osxdaily.com/2016/10/08/mac-app-store-temp-cache-folder/ (paraphrasing):


Quit out of the Mac App Store
Open Terminal and run open $TMPDIR../C/com.apple.appstore/
Hit Return and the com.apple.appstore folder will open in the Finder of Mac OS
Delete the contents of this folder


And finally:


Navigate to ~/Applications in Finder and move Xcode to the Trash [Note: This step was necessary for me, but ymmv]
Reboot
Launch App Store. Search for Xcode. Install it fresh.
