No visible @interface for ‘Playlist’ declares the selector 'initWithIndex:'

Hello guys,

I'm very new to IOS development. I followed every step of this video and the previous videos. It was working until I typed the following in the "PlaylistMasterViewController.m":

Playlist *playlist=[[Playlist alloc] initWithIndex:0];

It gives me the error message:

No visible @interface for ‘Playlist’ declares the selector 'initWithIndex:'

Any ideas? Thanks in advance!

i can only guess at your exact issue, but i am able to recreate the problem by removing the following from my Playlist.h file:

- (instancetype)initWithIndex:(NSUInteger)index;

for me, intuitively, the key phrase is "No visible @interface…"; this means that your code can't find that thing that you know exists. this "visibility" issue is about something being absent from the header, as the header is how classes "publicize" their contents to other classes.
