Hi everyone,
I’m trying to package my iOS game project in Unreal Engine 5.4 using a remote Mac build server (via SSH). The build step completes successfully, but the process fails during the cook stage with the error:
AutomationTool exiting with ExitCode=25 (Error_UnknownCookFailure)
The log doesn’t clearly indicate the root cause, even though all assets and plugins appear to load correctly. Here’s a summary of my setup:
UE Version: 5.4 (Windows host)
Remote Mac: Xcode 16.3
Target: iOS SDK …
Please help me I have the same error while using remote build through mac ios sdk 18 and xcode 16.3. So I need to upgrade atleast to UE5.6 to fix the error?
