Know if an array contains a type of element

I'm working with Swift 3 and Xcode.

I have a class :

class H: SKSpriteNode {...}

And an array :

var array = [H]()

I want to check with the nodes(at:) function if at given point, there is an element of type H. I tried :

if nodes(at: myPoint).contains(H)

But it doesn't work, and I understand that. Is there any way to be able to know if the arrays the nodes(at) function returns contains an element from the class H ?

And an other question, how can I check in all the nodes returned by the function, if the array contains a node with a specific name ?

Solution

  • Try to use .filter({ $0 is H }).count > 0 or .contains(where: { $0 is H })
