Appending elements to an array

Question

Hi all real newbie question here.

I have an array like this:

 var daysInMonth = Array<([MyCustomClass], NSDate)>()

How can I append an element to this?

I am having difficulty doing so. Trying something like this:

daysInMonth.append([MyCustomClass](), someDate)

or

daysInMonth.append(  ([MyCustomClass](), someDate)   )

will not work (i'd like to add an empty array initial above of type MyCustomClass, as well as some date that I have) but these are failing (error missing parameter #2 in call)

Any thoughts on what I am lacking in my syntax?

Thanks!

Answer 1

It looks like a swift bug to me. The swift compiler cannot correctly parse the "( (...) )" as passing in a tuple to a function.

If I break the append operation into two statements, it works.

var daysInMonth = Array<([MyCustomClass], NSDate)>()

let data = ([MyCustomClass()], NSDate()) // assuming MyCustomClass init() taks no parameter 

daysInMonth.append(data) 

note: It was [MyCustomClass]() in your question, which is incorrect.

Answer 2

Try declaring your array using the newer Array syntax instead:

var daysInMonth = [([MyCustomClass], NSDate)]()

Then, this works:

daysInMonth.append(([MyCustomClass](), NSDate()))
