iOS Core Graphics PDF: <Error>: replacing +/-infinity

[loon3y]

Ever since iOS 10, I have started having this issue. I had researched and it seems others also have this issue,

Can anyone else confirm this persists in iOS 10.2? Some have said that it was fixed in 10.2 but it still occurs on my source code.
