Let’s learn how to remove the title bar from your Mac Catalyst app.
We are using Swift Programming Language.
The code will look something like this:
(more…)Apple macOS
OS X (originally Mac OS X) is a series of Unix-based graphical interface operating systems (OS) developed and marketed by Apple Inc. It is designed to run on Macintosh computers, having been pre-installed on all Macs since 2002.
With the release of macOS Big Sur & macOS Monterey, the user cannot format External Hard Disk to ‘Mac OS Extended (Journaled, Encrypted)’ format as there is no option to do the same.
With the release of the macOS Big Sur Mac Operating System, Apple has removed the option under Disk Utility to allow users to format External Hard Drive to Mac OS Extended (Journaled, Encrypted) format.
Now there is only one option for Mac OS Extended (Journaled) but no option with encryption. It only allows users to format Hard Disk with Apple File System APFS without encryption, with encryption & with case sensitivity.
Here is how to apply UIVisualEffectView & UIBlurEffect to UITableView, UITableViewCell, UICollectionView, UICollectionViewCell, UIView / View in your Apple iOS / iPadOS or macOS Catalyst App.
As Apple describes UIVisualEffectView & UIBlurView in its support document as follows:
Depending on the desired effect, the effect may affect content layered behind the view or content added to the visual effect view’s contentView. Apply a visual effect view to an existing view and then apply a UIBlurEffect or UIVibrancyEffect object to apply a blur or vibrancy effect to the existing view. After you add the visual effect view to the view hierarchy, add any subviews to the contentView property of the visual effect view. Do not add subviews directly to the visual effect view itself.
So in simple words, you don’t have to use Adobe Photoshop to get blur effect and fake superimpose on your UIView rather you can get the same effect programmatically for every situation without any hassle.
Note: If you are using UIVisualEffectsView in your app I would strongly suggest you use a system setting called ‘Reduced Transparency’ to condition code it. If the user doesn’t want transparency or Blur or Vibrancy effect for all of the apps in his iPhone or iPad or Mac he can just do it with a single switch in the settings app. Another note view that you are applying effect should preferably be the Popover View Controller. Another thing is to remember to replace the below blue color with the UIColor of your choice with alpha channel transparency.
For UITableView and UITableViewCell, use following code in your UITableViewController’s viewWillAppear function:

Programmatically get iOS, iPadOS, macOS Catalyst Operating System Name and Version and a model identifier of iPhone, iPad, Mac devices.
Here is a simple way to programmatically get the operating system name and version of your iOS, iPadOS and macOS.
The below code will also return the value of iPhone, iPad and Mac Model identifier to help you know if it’s MacBook or iMac in Mac’s case or iPhone 11 Pro or iPhone 13 Pro etc.
Step 01: First import IOKit, It is only required for macOS Catalyst app-specific code.

Before we jump into implementing WKWebView I would first introduce you to why you want to use it. WKWebView helps you when you want to load a webpage inside your app without throwing users to a third party browser outside of your app.
Let’s start coding,
Step 01: First Import WebKit
import WebKit
Step 02: Add ‘WKNavigationDelegate’ to your declaration of ViewController Class
WKNavigationDelegate
It will look something like this:
class ViewController: UIViewController, WKNavigationDelegate {
}
Step 03: Now create two variables for loading webView and one for button which will close webView
var webView: WKWebView! var closeWebViewUIButton = UIButton(type: .system) as UIButton
Step 04: Now naviagte to your ViewDid Load method
override func viewDidLoad() {
super.viewDidLoad()
}
Step 05: Now in your ViewDidLoad method add the following code, Which will load WKWebView. You can change the URL as per your preference.
