I am trying to compile the Vuforia Core Samples and I am getting the following error message in Xcode. I have attempted to clean the build folder, deleted the Derived Data folder, disabled the Metal Editor Support, but still the problem persists.
ld: can't open output file for writing: /Users/gmead/Library/Developer/Xcode/DerivedData/Unity-iPhone-albzhtibxamjymdddgixlcwzwsws/Build/Products/ReleaseForRunning-iphoneos/vuforia.app/vuforia, errno=21 for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
The above happens with both of the following configurations...
MacOS 10.14.5, Unity 2018.4.3f1, Vuforia 8.3.8, and Xcode 10.2.1
MacOS 10.14.5, Unity 2019.1.9f1, Vuforia 8.3.8, and Xcode 10.2.1
Any help would be greatly appreciated, thanks in advance.
