//Error when try to get .txt file contentsof

Error Domain=NSCocoaErrorDomain Code=264 "The file “somelog-log.txt” couldn’t be opened because the text encoding of its contents can’t be determined." UserInfo={NSFilePath=/var/mobile/Containers/Data/Application/199D8E4D-6DFC-4327-BC57-06957BCC6EA3/Documents/somelog-log.txt}

Solution

  • Specify the encoding explicitly

    let result1 = try String(contentsOf: shareLog, encoding: .utf8)
