How to tell if an array contains an object
Swift version: 5.0
It's easy to find out whether an array contains a specific value, because Swift has a contains() method that returns true or false depending on whether that item is found. For example:
let array = ["Apples", "Peaches", "Plums"]
if array.contains("Apples") {
print("We've got apples!")
} else {
print("No apples here – sorry!")
}That example array does indeed contain "Apples" so that code will print "We've got apples!" to the Xcode console.
