Trying to compile the following code snippet causes the compiler error below. The code is part of CorePlot's CPTNumericData.m file.

case CPTComplexFloatingPointDataType:
                switch ( self.sampleBytes ) {
                    case sizeof(float complex):
                        result = @( crealf(*(const float complex *)[self samplePointer:sample]) );
                        break;

                    case sizeof(double complex):
                        result = @( creal(*(const double complex *)[self samplePointer:sample]) );
                        break;
                }
                break;

Error: C-style cast from 'const void * _Nullable' to 'const float' is not allowed
