This question is an exact duplicate:

There is a Cli_DBRead code (1000,48,4, UnsafeMutalabRawPointer!) With UnsafeMutalabRawPointer! It is necessary to consider the variable how to do it. Tell me please. This code reads data from the controller and must write to UnsafeMutalabRawPointer! I cannot read from there and write to a variable

  • usually we assign first a variable of the type let a = int and how to write a variable in the code and assign it a value - Marat Gafarov

Apparently this is a tuple. Access to the elements of the tuple is so

var (_, _, _, yourVar) = Cli_DBRead

for the test

 print(" necessaryVar - \(yourVar)")
