So let's say I have a class like this:
class Employee: NSObject {
var id: String?
var someArray: [Employee]?
}
I use reflection to get the property names:
let employee = Employee()
let mirror = Mirror(reflecting: employee)
propertyNames = mirror.children.flatMap { $0.label }
// ["businessUnitId", "someArray"]
so far so good! Now i need to be able to figure out the type of each of these properties, so if I do the employee.valueForKey("someArray")
, it won't work because it only gives me the AnyObject type. What would be the best way to do this? Specially for the array, I need to be able to dynamically tell that the array contains type of Employee
.
You don't need to inherit from NSObject
(unless you have a good reason to).
class Employee {
var id: String?
var someArray: [Employee]?
}
let employee = Employee()
for property in Mirror(reflecting: employee).children {
print("name: \(property.label) type: \(type(of: property.value))")
}
Output
name: Optional("id") type: Optional<String>
name: Optional("someArray") type: Optional<Array<Employee>>
This also works with Structs
