Staged Build Directory Invalid, Unable to Build for IOS via Remote Build

[NoahBeggs]

Am unable to package for IOS via remote build due (at least in part) to a problem with the staged build directory. Specifically, the directory is being called invalid. Steps to reproduce below:

1. Create any default AR project (appears to work with any project that requires remote build, but tested most with fresh AR projects)
2. Upload provisioning profile and certificate in project settings → IOS (development and distribution provisioning profiles have same effect)
3. Set up remote build SSH key
4. Package for IOS
5. Build fails with warning “UATHelper: Packaging (IOS): WARNING: To run, you must have a valid staged build directory”
6. Create directory manually on apple machine (Project settings no longer includes a way to set the staging directory, so cannot set from there). Package for IOS. During build, directory is deleted automatically, resulting in same error.

Feel this may just be a bug, but, UAT and remote building for IOS are weird. Maybe something has just changed that I’m unaware of?

Any help, even pointing me in the right direction, is appreciated!

Found a workaround!

Problem seems to stem from using modern Xcode.

To change this:

1. On your Windows machine, go to your engine install location and find BaseEngine.ini (e.g. “Program Files\Epic Games\UE_5.4\Engine\Config\BaseEngine.ini”).
2. Open the file, find “[/Script/MacTargetPlatform.XcodeProjectSettings]”, and underneath change “bUseModernXcode=true” to “bUseModernXcode=false”.
3. Save BaseEngine.ini
4. Open your project, package for IOS

Of note, this was the same solution for some other IOS problems during 5.3, see forum post here
