If you get the below SharePoint 2013 App Development

Error "App domain must be configured prior to completing this operation"

You need to Configure an Isolated application domain to Install and run SharePoint 2013 App. Ofcourse the application domain has to be added into the bypass list and trusted sites list to avoid authentication prompts.

Also you need to disable loopback check to avoid authetication issues.

Disabling Loopback Check:

1. Backup registry of the target machine.
2. Open registery editor(by typing regedit.exe or regedt32.exe in Start->Search program and files)
3. Add DWORD registry value DisableStrictNameChecking HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\LanmanServer\Parameters and set it to 1 with base type Decimal
4. Add DWORD registry value DisableLoopbackCheck at HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa and set it to 1 with base type Decimal
5. Close registery editor. Restart the machine
6. Deploy the app again.
7. Launch the app locally.
