Invalid numeric value (NaN, or not-a-number) to CoreGraphics API

[DerJojo11]

When I open a PDF in iOS, my Debug Console get a lot of Errors.

It is always the same Error:

CGContextAddLineToPoint: no current point.
CGContextClosePath: no current point.
Error: this application, or a library it uses, has passed an invalid numeric value (NaN, or not-a-number) to CoreGraphics API and this value is being ignored. Please fix this problem._
If you want to see the backtrace, please set CG_NUMERICS_SHOW_BACKTRACE environmental variable.

I start looking for the error and find something from StackOverflow. I tried it out and this fix it.

- (instancetype)initWithFrame:(CGRect)frame
                    arguments:(id _Nullable)args
                    controler:(nonnull FLTPDFViewController *)controler {
    if ([super init]) {
        _controler = controler;
        
        // Adding this CGRect instead of frame solved the problem
        CGRect rect = CGRectMake(0, 0, 100, 100);
        _pdfView = [[PDFView alloc] initWithFrame: rect];
        _pdfView.delegate = self;
