iOS getting stuck at multiple commands found I am new to iOS programming and many times I get stuck at this error: Multiple commands produce '/Users/**/Library/Developer/Xcode/DerivedData/**-abmytreyrhipzhhcspsondoytpxp/Build/Intermediates.noindex/**.build/Debug-iphoneos/**.build/Objects-normal/arm64/Models.stringsdata' I have checked copy bundle resources no such duplicate entity found. Is there any way I can figure out which string data is duplicate and where ?
