detecting fundamental frequency of human voice in iOS

I make a wide search about this , I found many useful code examples but they did not gave me the exact result

I need to detect fundamental frequency (F0) of human voice while someone fonating a: vowel.

then I look up these code examples;

https://github.com/krafter/DetectingAudioFrequency from krafter https://github.com/syedhali/EZAudio

but none of them gave me the fundamental frequency , all of them gives the strongest frequency so this usually equals to F2 or F3 harmonics. I need help to calculate the fundamental frequency with this code examples by modifying the code.

You can't modify an FFT peak detector for correct voice pitch estimation. It's the wrong algorithm. Instead, try autocorrelation, or one of the answers to this question: how to know the fundamental frequency is right detected by fft/lomb-scargle?
