Im having Problems , is that due to a new update?

Ive been following the whole video bit by bit and using the same code but an error of " Implicit declaration of function NSlog is invalid in C99 ?

1 Answer

This error might occur due to two reasons:

  1. ObjectiveC is a case sensitive language so use the correct keyword NSLog instead of NSlog
  2. You might not have imported the Foundation Framework in your project.

Hope this will solve the error :)
