tkrajacic / PropertyObserver.swift
Last active November 4, 2015 19:14
Why is the property observer called if no assignment takes place?
var value : String = "Test" {
didSet {
print("Changed Item Value")
}
}
let newValue = "Test"
private func changeIfNew<T: Comparable>(inout current: T, new: T) {
// This evaluates to false (as current == new) and the loop is skipped yet the property observer is still triggered
if current != new {
