how to check if a property value exists in array of objects in swift

Question

I am trying to check if a specific item (value of a property) exists in a array of objects, but could not find out any solution. Please let me know, what i am missing here.<

Answer 1

You can filter the array like this:

let results = objarray.filter { $0.id == 1 }

that will return an array of elements matching the condition specified in the closure - in the above case, it will return an array containing all elements having the id property equal to 1.

Since you need a boolean result, just do a check like:

let exists = results.isEmpty == false

exists will be true if the filtered array has at least one element
