This code work till Swift 3.2. But I'm using Swift 4 and it's giving me an empty Array[String].
You can get `properties like below :
class ClassTest {
var prop1: String?
var prop2: Bool?
var prop3: Int?
}
let mirror = Mirror(reflecting: ClassTest())
print(mirror.children.flatMap { $0.label }) // ["prop1", "prop2", "prop3"]
You can use this:
extension NSObject {
func propertyNames() -> [String] {
let mirror = Mirror(reflecting: self)
return mirror.children.compactMap{ $0.label }
}
}
