notes from a developer, tutorials, how-to, ideas
Today I want to share a simple way to retrieve user data from a native iOS cache image, automatically generated when your app goes in background.
You can retrieve this kind of informations if your phone was lost or Jailbreaked or connecting it to your pc and open an old backup. You can use tools like iBackup Viewer and more…
Let’s see how it works!

Simple code snippet today that show how to push a UIView and obtain the same effect of a UINavigationController as push action, choosing also the side (.fromLeft / .fromRight).
We can do this using the CATransitionanimations. Very simple:
func push( view: UIView, side: CATransitionSubtype = .fromRight ) {
let transition = CATransition()
transition.type = CATransitionType.push
transition.subtype = side
self.layer.add(transition, forKey: nil)
self.addSubview(view)
}
Enjoy pushing!
Quick memo to get the keyWindow for all iOS versions until now.
KeyWindow is the “key” window of your entire application. The key window receives keyboard and other non-touch related events. Only one window at a time may be the key window.
Use the #available(iOS 13.0, *) keyword to bypass system check:
As personal utility I’ve created a new FlatUIColor Cocoapod framework.
Consist of a simple UIColor extension with a customized set of my favorite flat colors that I use very often.
To integrate in your project, simply add this line in your Podfile:
pod 'FlatUIColors', :git => 'https://github.com/elpsk/FlatUIColors.git'
Install pods from terminal: $ pod install and open your project $ xed .
Every time you upload a screenshot on the App Store for a new app submission, you receive from Apple this error message:

Today I want to introduce an Apple framework, called Multipeer Connectivity.
“The Multipeer Connectivity framework supports the discovery of services provided by nearby devices and supports communicating with those services through message-based data, streaming data, and resources (such as files). In iOS, the framework uses infrastructure Wi-Fi networks, peer-to-peer Wi-Fi, and Bluetooth personal area networks for the underlying transport. In macOS and tvOS, it uses infrastructure Wi-Fi, peer-to-peer Wi-Fi, and Ethernet.”

I want to simplify the coding like, so I use this solution. Easy and simple for me and I want to share:

I want to introduce you to the new “App Icon Maker“, a simple and free utility for macOS that helps you to convert the images in the 3 Apple formats, @1x, @2x, and @3x.
PrivateFrameworks are always a joy.
Today, for a personal project I discovered how to use private Login.framework to lock programmatically via code (Swift or C) the screen of my mac book.
