Regular distributions of Xcode are now available exclusively from the OS X App Store, but (like many, I expect) my App Store account and developer accounts use different Apple IDs. All my previous installations of Xcode have used my developer account, and I also wonder if there are critical parts of the Xcode configuration (e.g. provisioning profiles, etc.) that rely on Xcode having been installed using the developer Apple ID.
Are there any undesirable consequences to simply installing Xcode from the App Store using my personal account? Or, should I (can I, must I) log in to the App Store using my developer Apple ID instead?
You can use whatever Apple ID you want to download Xcode from the Mac App Store. There’s nothing special about what it downloads. You’ll need to log in to the developer portal though to download beta versions.
