Existing signed IPA
ProductionAn IPA is a compiled, signed iOS application. Its embedded bundle ID and native code cannot be rewritten by LaunchLayer.
What you need
A valid signed IPA, matching App Store Connect application, Apple credentials, and an acceptable version/build number.
What LaunchLayer does
Inspects embedded identity and version, enforces exact bundle-ID matching, runs deployment preflight, uploads through the configured workflow, and monitors Apple processing.
What you still need to do
Rebuild from source for native-feature or embedded-icon changes, complete TestFlight testing, listing details, review submission, and Apple requirements.
Common problems
Invalid IPA, bundle-ID mismatch, expired signing assets, duplicate build number, App Store app mismatch, or Apple processing delays.
