Why isn't xcode updating?

I have used Xcode for a while, but, I decided to update Xcode. I did this because Xcode didn't support iOS 9.3. I have tried and tried to update Xcode directly from the app store but have had no success. Does anyone know why Xcode won't update from the app store? 😢

I have the same issue. Have you found a solution?
