Swift: check empty array

Question

array = [
    “test” = test
    “test1” = test
    “test2” = test  
    “test4” = test  
]

Check if test3 is in the array

I tried to do this:

if let check= userObject[“test3”]{

}

My app crashes and I get this error: unexpectedly found nil while unwrapping an Optional value

You need to have commas separating your objects, and that's a dictionary, not an array.

var dict: [String: AnyObject] = [:]

dict = [
    "test": test,
    "test1": test,
    "test2": test,  
    "test4": test 
]
