After trying many things I just ended up deleting the view controller in the storyboard and recreating it from scratch and the problem disappeared. I’m not sure what was the issue, maybe some bug in Xcode…

When that function returns, the block becomes unused and can be used the next time a function is … Read more

strtok() divides the string into tokens. i.e. starting from any one of the delimiter to next one would be your one token. In your case, the starting token will be from “-” and end with next space ” “. Then next token will start from ” ” and end with “,”. Here you get “This” … Read more
++ is not an operator. It is two + operators. The + operator is the identity operator, which does nothing. (Clarification: the + and – unary operators only work on numbers, but I presume that you wouldn’t expect a hypothetical ++ operator to work on strings.) Parses as Which translates to You have to use the slightly longer += operator to do what you want to do: I suspect the ++ and — operators … Read more

The splice() method changes the contents of an array by removing existing elements and/or adding new elements. Run code snippet The second parameter of splice is the number of elements to remove. Note that splice modifies the array in place and returns a … Read more
