Hi there,
We recently hit this problem, and after a lot of head-scratching have solved it.
To be clear you don’t need a Mac or XCode to get blueprint projects onto an iOS device.
What we think caused our problem was changing the Display name in the iOS settings.
To fix it for us, we:
- deleted Saved, Intermediate, Build and Binaries folder
- Tracking down changes behind the scenes, we found a couple of extra lines in Config/defaultengine.ini (under ios runtime settings). BundleDisplayName and BundleIdentifier had been set.
- Deleting those two lines fixed the issue for us, in addition to deleting the folders listed above
Hope that helps!
