Swift 4 Array of Objects contains String Value

Question

I have an dataArray

struct FirebaseDataGlobal {
    let symbol: String!
}

var dataArray = [FirebaseDataGlobal]()

I need to check if this array contains a specific String. Something like below.

if dataArray.contains("string") {
  print("string found")
}

How can i do this? Can i use a function like this if the dataArray is empty?

Use contains(where:):

if dataArray.contains { $0.symbol == "some string" } {
    print("found one")
}

Can this be used if the array is empty?
