Function to Read short text file into Swift

I need a Swift 4 function in OSX to read in text files with the following format: 8 Fill Level 0% 8 0 0.1 0.2 0.3 0.5 0.7 0.8 1 0.05 0.04 0.04 0.035 0.03 0.03 0.02 0 10% 9 0 0.1 0.15 0.2 0.3 0.5 0.7 0.9 1 0.4 0.4 0.4 0.25 0.26 0.26 0.25 0.25 0 ... Here is the ~~ c# code that read it in. You don't need to follow this code but it shows the structure. Hopefully there is an easier way to read this in with Swift. var NFL: Int var NP: [Int] var FLEV: [Double] var GNU: [[Double]] var LAM: [[Double]] init() { var type = 4 } /// <summary> /// Read Fluid Curves /// </summary> func ReadFluidCurves() -> Bool { var fileName = "[login to view URL]" StreamReader input = new StreamReader(fileName); NFL = [login to view URL]( ReadJunk( input)); FLEV = new double[NFL]; NP = new int[NFL]; GNU = new double[NFL][]; LAM = new double[NFL][]; for (int i=0;i<NFL;i++) { FLEV[i] = [login to view URL]( ReadJunk( input)); NP[i] = [login to view URL]( ReadJunk( input)); GNU[i] = new double[NP[i]]; for (int j=0;j<NP[i];j++) { GNU[i][j] = [login to view URL]( ReadJunk( input)); } LAM[i] = new double[NP[i]]; for (int j=0;j<NP[i];j++) { LAM[i][j] = [login to view URL]( ReadJunk( input)); } } return true } func ReadJunk(StreamReader input) -> String { char[] buffer = new char[10]; String buildup = ""; [login to view URL](buffer, 0, 1); while (buffer[0] == ' ' || buffer[0] == (char)13 || buffer[0] == (char)10 ) { [login to view URL](buffer, 0, 1); } buildup = new String( buffer[0], 1); [login to view URL](buffer, 0, 1); while (buffer[0] != ' ' && buffer[0] != (char)13 && buffer[0] != (char)10) { buildup = buildup + new String( buffer[0], 1);; [login to view URL](buffer, 0, 1); } return buildup; }
