Answer 1

The error message is a bit misleading but try initializing the array before assigning it:

var c: Array<PostCategory> = []

...or...

var c = Array<PostCategory>()

Answer 2

I bet your PostCategory is a struct. Apparently struct arrays aren't convertible to an Any array. This is weird because all types conforms to the Any protocol.

If you change the PostCategory to a class instead, it should work fine. You might need to create a new initializer for the class though, since classes doesn't give you the same default initializer as a struct does.

Yes, PostCategory is a struct, Is there anything equivalent of Any for struct – Derbyshire
