PBXCp Error No Such File or Directory Error for Certain Fonts

[MaxwellGover]

I'm trying to build my react native project onto my actual device but these errors are causing the build to fail.

CpResource /Users/maxwellgover/Desktop/nimbus/node_modules/native-base/Fonts/Arial\ Black.ttf /Users/maxwellgover/Library/Developer/Xcode/DerivedData/nimbus-dwhroufdxzvgkcajekmlbluemoyy/Build/Products/Debug-iphoneos/nimbus.app/Arial\ Black.ttf
    cd /Users/maxwellgover/Desktop/nimbus/ios
    export PATH="/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin:/Applications/Xcode.app/Contents/Developer/usr/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin"

Going to resources folder in xcode and deleting all the fonts highlighted in red solved the issue.
