How to Find an Object in an Array with a Specific Property Value

[kjmcneish]

To search for an object in an array with a specific property value, you can use the array's filter method. For example, the following code returns an array of PersonEntity objects whose last name is "Smith":

Code: [Select]

let personEntity = self.personEntityList.filter{ $0.lastName == "Smith"}.first
When searching on a property that contains unique values (one that guarantees a single entity is found), you can use the first property to return a single entity:

Code: [Select]

let personEntity = self.personEntityList.filter{ $0.SSN == "123-45-6789"}.first
All the best!
