We will explore our ways to identify device of user whether it is iPad or iPhone, We will do all this in Swift Programming Language with latest Xcode build.

 
There four ways that iOS device will get identified .phone, .pad, .tv & .unspecified.

 
So code will look like this in swift

 

if (UIScreen.main.traitCollection.userInterfaceIdiom == UIUserInterfaceIdiom.pad) {
    print("It's iPad")
    // Your code here
    
} else if (UIScreen.main.traitCollection.userInterfaceIdiom == UIUserInterfaceIdiom.phone) {
    print("It's iPhone")
    // Your code here
    
} else if (UIScreen.main.traitCollection.userInterfaceIdiom == UIUserInterfaceIdiom.tv) {
    print("It's Apple TV")
    // Your code here
    
} else if (UIScreen.main.traitCollection.userInterfaceIdiom == UIUserInterfaceIdiom.unspecified) {
    print("It's Unknown Device")
    // Your code here
    
}

How to secure macOS – OSX & iOS Wi-Fi Network with recommended settings for Wi-Fi routers and access points

Mandar Apte Apple, Apple iOS, Apple Mac OSX, Tutorials Leave a comment

I will list down steps to secure your macOS & iOS Wi-Fi Network.

 

Step 01: First things first, Update you Macintosh, iPhone, iPad, iPod touch & even AirPort Express, Airport Extreme base stations for latest software using Mac App Store.

 

Step 02: Choose Unique & Safe SSID (Service Set Identifier) Wi-Fi network name

 
Wi-Fi network name is case sensitive. Choose a unique name for your network and that isn’t shared by other nearby networks. If your SSID isn’t unique, Wi-Fi devices will have trouble identifying your network. This could cause network device to fail to automatically connect to your network, or to connect to other networks sharing the same SSID.

Mandar Apte Apple, Apple iOS, Apple Xcode, Tutorials Leave a comment

Here is situation in your Xcode project that you want to call method from another class swift file to your original class of swift file.

 
Let’s call your original swift class file ‘FirstViewController’ which has ‘UIViewController’ as super class.

 
Second swift that you want to call function from we will assume that it has ‘SecondViewController’ as class name & it has ‘UIViewController’ as super class.

 
You have written function called ‘printSomething()’ in your ‘SecondViewController’ that would be triggered when somebody taps on button present on ‘FirstViewController’ as IBAction called ‘printThis(sender: UIButton)’

 
So you will write printThis function as follows:

How to use Disk Utility to partition Hard Disk / Solid State Disk Drive on Mac

Mandar Apte Apple, Apple Mac OSX, Tutorials Leave a comment

Macintosh OSX Disk Utility

 

As Wikipedia Says: Disk Utility is a system utility for performing disk and disk volume-related tasks on the OS X operating system by Apple Inc.

 
Day to day functions supported by Disk Utility are:

 

  • Creation, conversion, backup, compression and encryption of logical volume images from a wide range of formats read by Disk Utility to .dmg or, for CD/DVD images, .cdr
  • Mounting, unmounting and ejecting external disk volumes
  • Enabling or disabling journaling
  • Verifying a disk’s integrity, and repairing it if the disk is damaged
  • Erasing, formatting, partitioning and cloning disks
  • Secure deletion of free space or disk using a “zero out” data, a 7-pass DOD 5220-22 M standard, or a 35-pass Gutmann algorithm
  • Adding or changing partition table between Apple Partition Table, GUID Partition Table and master boot record (MBR)
  • Restoring volumes from Apple Software Restore (ASR) images
  • Checking the S.M.A.R.T. status of a hard disk
  • Disk Utility functions may also be accessed from the OS X command line with the diskutil and hdiutil commands.

 
Now will learn how to partition disk,

 

Important Note:

  • Partitioning a disk erases all the data previously stored on it
  • By using partition feature of disk utility it divides disk into sections called ‘partitions’ which appear on the desktop as separate disks.

 

Precaution: Before moving forward backup all your computer data using Time Machine on different hard drive other than that you are currently partitioning.

 

Here is how to Partition a disk

 
Step 01: Connect External Disk to your Mac using USB / FireWire cable for purpose partitioning it

 
Step 02: Locate ‘Disk Utility App in Applications > Utilities

Introduction:

 
What is Battery life?

 
Battery life is the amount of time your device runs before it needs to be recharged.

 
What is Battery lifespan?

 
Battery lifespan is the amount of time your battery lasts until it needs to be replaced.

 

General Performance Tips & Solutions

 

  • Update your Apple device to the latest software updates & operating system:

    • Apple software updates often include advanced energy-saving technologies, so always make sure your device is running with the latest version of iOS, OS X, or watchOS.

     

  • Avoid extreme ambient temperatures: Your device is designed to perform well in a wide range of ambient temperatures, with 62° to 72° F (16° to 22° C) as the ideal comfort zone. Avoid exposing your device to ambient temperatures higher than 95° F (35° C), which can permanently damage battery capacity.
