Re-implementation of @binding and @State (from SwiftUI) myself to better understand it
/*:
This is a concept re-implementation of the @Binding and @State property wrappers from SwiftUI
The only purpose of this code is to implement those wrappers myself
just to understand how they work internally and why they are needed,
⚠️ This is not supposed to be a reference implementation nor cover all
subtleties of the real Binding and State types.
The only purpose of this playground is to show how re-implementing
them myself has helped me understand the whole thing better
/// `ObjectBinding` used as a way to create a `Binding` from a `BindableObject`. In this case the ViewModel
/// complies with `BindableObject` which is then translated into a `Binding` which is what `Toggle` is expecting
/// NOTE: Since it's a `DynamicViewProperty`, after its value is changed, the body will be updated.
class ViewModel: BindableObject {
let didChange = PassthroughSubject<ViewModel, Never>()
var isEnabled = false {
didSet {
didChange.send(self)

Making efficient use of the libdispatch (GCD)

libdispatch efficiency tips

The libdispatch is one of the most misused API due to the way it was presented to us when it was introduced and for many years after that, and due to the confusing documentation and API. This page is a compilation of important things to know if you're going to use this library. Many references are available at the end of this document pointing to comments from Apple's very own libdispatch maintainer (Pierre Habouzit).

My take-aways are:

  • You should create very few, long-lived, well-defined queues. These queues should be seen as execution contexts in your program (gui, background work, ...) that benefit from executing in parallel. An important thing to note is that if these queues are all active at once, you will get as many threads running. In most apps, you probably do not need to create more than 3 or 4 queues.

  • Go serial first, and as you find performance bottle necks, measure why, and if concurrency helps, apply with care, always validating under system pressure. Reuse

XML Vulnerabilities and Attacks cheatsheet

XML Vulnerabilities

XML processing modules may be not secure against maliciously constructed data. An attacker could abuse XML features to carry out denial of service attacks, access logical files, generate network connections to other machines, or circumvent firewalls.

The penetration tester running XML tests against application will have to determine which XML parser is in use, and then to what kinds of below listed attacks that parser will be vulnerable.
