Swift Bharat – The conference like never before in India

September 30, 2025 by Ashish Kakkad

So, two months ago, I saw that a big conference was taking place in Bangalore which was named “Swift Bharat”. Also, I checked that the speaker lineup was so good. I was discussing it with my wife, as she is also an iOS Developer. She said yes yes, it’s your passion. You definitely have to go. Then I booked tickets quickly in the early bird along with some of my friends from Swift Ahmedabad (Gujarat, India).

Also, there was one other event that was taking place together, which was “Meet with Apple” in Bangalore too!!! And it’s about “Build delightful visuals and animations with SwiftUI”. I had registered for that too.

So, let me drive to that day directly.

iOS Lifecycle: Handling willEnterForeground in AppDelegate and SceneDelegate

June 1, 2025May 31, 2025 by Ashish Kakkad

Hope you guys already know that we need to migrate to scene-based life cycle in near future.

Below lines are written in this reference document provided by Apple.

In iOS 18.4, iPadOS 18.4, Mac Catalyst 18.4, tvOS 18.4, visionOS 2.4 and later, UIKit logs the this message for apps that haven’t adopted the scene-based life-cycle.

This process does not adopt UIScene lifecycle. This will become an assert in a future version.

Soon, all UIKit based apps will be required to adopt the scene-based life-cycle, after which your app won’t launch if you don’t. While supporting multiple scenes is encouraged, only adoption of scene life-cycle is required.

Here I am discussing about the methods applicationWillEnterForeground and sceneWillEnterForeground actually work same or not? As there are key differences let’s discuss in detail.

How to prevent screenshot for UIView in iOS?

April 23, 2023July 18, 2022 by Ashish Kakkad

iOS – Apple provides screenshot detection notification but not providing direct solution for prevention.

Here I found solution for preventing screenshot taking from the UIView. It’s a simple extension of the UIView that allows to hide it from screen-capturing and also from screen recording. The solution uses ability of UITextField to hide a password from capturing.

	extension UIView {
	func preventScreenshot() {
	DispatchQueue.main.async {
	let field = UITextField()
	field.isSecureTextEntry = true
	self.addSubview(field)
	field.centerYAnchor.constraint(equalTo: self.centerYAnchor).isActive = true
	field.centerXAnchor.constraint(equalTo: self.centerXAnchor).isActive = true
	self.layer.superlayer?.addSublayer(field.layer)
	field.layer.sublayers?.first?.addSublayer(self.layer)
	}
	}
	}

view raw PreventScreenshot.swift hosted with ❤ by GitHub

Usage:

viewSecure.preventScreenshot()

So, when you take screenshot the logic of text field secure entry (password text field) will not allow to take screenshot of that part.

ScrollView Screenshot Prevention

Update: Here is recursive function for preventing screenshot.

	extension UIView {
	func preventScrollViewScreenshotRecursive() {
	guard superview != nil else {
	for subview in subviews {
	subview.preventScrollViewScreenshotRecursive()
	}
	return
	}
	let guardTextField = UITextField()
	guardTextField.backgroundColor = .red
	guardTextField.translatesAutoresizingMaskIntoConstraints = false
	guardTextField.tag = Int.max
	guardTextField.isSecureTextEntry = true

	addSubview(guardTextField)
	guardTextField.isUserInteractionEnabled = false
	sendSubviewToBack(guardTextField)

	layer.superlayer?.addSublayer(guardTextField.layer)
	guardTextField.layer.sublayers?.first?.addSublayer(layer)

	guardTextField.centerYAnchor.constraint(
	equalTo: self.centerYAnchor
	).isActive = true

	guardTextField.centerXAnchor.constraint(
	equalTo: self.centerXAnchor
	).isActive = true
	}
	}
