The short version

  • Each has a real cost: Firebase spark plan limited to 1 GiB storage, 50,000 daily reads, 20,000 daily writes; Xcode slow build times, particularly in Xcode 13 with builds 10-20 times longer than Xcode 12
  • They diverge on capability: Firebase covers Real-time Database, Xcode covers Source code editor.
  • Prices and features above were last checked on 30 August 2026.
