Definitely this is a bug.

The UAT file /Engine/Source/Programs/AutomationTool/IOS/IOSPlatform.Automation.cs

line 1137 may be a mistake

The engine was downloaded from Epic and the code has been modified, but it doesn’t work. How can I continue.

Hi,
This does appear to be legitimate bug as pointed out by @akbot48. One alternative is to migrate the project to ‘Automatic Signing’ to avoid this path in Unreal AutomationTool. However, if manual code signing is necessary, you would need to patch $UE_ROOT/Engine/Source/Programs/AutomationTool/IOS/IOSPlatform.Automation.cs:

  1. string AllText = File.ReadAllText(MobileProvisionDir.FullName);

with

  1. string AllText = File.ReadAllText(MobileProvisionFile.FullName);

and rebuild UAT. If you are running on a Launcher build, you would need to drop the contents of the attached Zip into $UE_ROOT/Engine/Build/BatchFiles and run

  1. sh $UE_ROOT/Engine/Build/BatchFiles/BuildUAT.sh

    Best regards
