What is Algorithm? Algorithm Basics Algorithm means “a process or set of rules to be followed in calculations or other problem-solving operations”. Therefore Algorithm refers to a set of rules/instructions that step-by-step define how a work is to be executed upon in order to get the expected results. In mathematics and computer science, an algorithm […]
Frameworks of IOS listed as follows MediaAccessibility Coordinate the presentation of closed-captioned data for your app’s media files. JavaScriptCore The JavaScriptCore Framework provides the ability to evaluate JavaScript programs from within Swift, Objective-C, and C-based apps. You can use also use JavaScriptCore to insert custom objects to the JavaScript environment. SpriteKit SpriteKit is a graphics […]
A file or file reference URL (as determined with fileURL), this property’s value is suitable for input into methods of NSFileManager or NSPathUtilities. NSFileManager or NSPathUtilities The NSFileManager class provides convenient access to a shared file manager object that is suitable for most types of file-related manipulations. A file manager object is typically your primary […]
Passing data between view controllers in Objective-C Passing data between view controllers,When designing an app that makes use of multiple view controllers it may become necessary to pass data back and forth between the view controllers. Passing data to the next view controller as well as passing data back to the previous view controller. There […]
Structures and classes in swift are general-purpose, flexible constructs that become the building blocks of your program’s code. You define properties and methods to add functionality to your structures and classes using the same syntax you use to define constants, variables, and functions. Structures and Classes properties to store values methods to provide functionality subscripts […]
Control Flow in Swift, These include while loops to perform a task multiple times; if, guard, and switch statements to execute different branches of code based on certain conditions; and statements such as break and continue to transfer the flow of execution to another point in your code. For-In Loops for-in loop to iterate over […]
Concurrency in Swift has built-in support for writing asynchronous and parallel code in a structured way. Asynchronous code can be suspended and resumed later, although only one piece of the program executes at a time.Suspending and resuming code in your program lets it continue to make progress on short-term operations like updating its UI while […]
Time complexity in DSA is the computational complexity that describes the amount of computer time it takes to run an algorithm. Time complexity is commonly estimated by counting the number of elementary operations performed by the algorithm, supposing that each elementary operation takes a fixed amount of time to perform. Thus, the amount of time […]
In the Objective-C programming language, Objective-C data types refer to an extensive system used for declaring variables or functions of different types. The type of a variable determines how much space it occupies in storage and how the bit pattern stored is interpreted. What are the main objective of data types?Answer: A data type constrains […]
If you want to convert jpg to word, then you have certainly landed in the right place. In this post, we are going to tell you about the best ways that you can use to change an image into ms word format. Along with the perfect way to convert jpg files to word, you will […]
In programming, as in life, you have to make decisions and act on them. Objective-C provides control statements and loops to help your program take action. You may want to repeat a set of instructions based on some condition or state, for example, or even change the program execution sequence. Here is the basic syntax […]
Objective-C Operators , Objective-C also provides a set of so called logical operators designed to return boolean true and false. The OR (||) operator returns 1 if one of its two operands evaluates to true, otherwise it returns 0 sizeof Operator Conditional Expression Address Operator Pointer * operator Arithmetic Operators Operator Description + Adds two […]
Functions and Methods in Objective-C,A function is a named block of code that can be called upon to perform a specific task. It can be provided data on which to perform the task and is capable of returning a result to the code that called it. The function can be programmed to accept the values […]
Swift Functions are self-contained chunks of code that perform a specific task. You give a function a name that identifies what it does, and this name is used to “call” the function to perform its task when needed. A Swift 4 function can be as simple as a simple C function to as complex as […]
How to Troubleshoot the Scanner of an all-in-one printer is a straightforward process of elimination. You begin at the most basic level, striking off those issues that are not the problem and work your way up the ladder of complexity until you have a working scanner. The computer does not recognize a scanner Verify the […]
Troubleshooting your Mac, The first things I’d try are to reset both the NVRAM and SMC in that order. Before following the steps below, ensure you have no external hardware connected and make sure you use the built-in keyboard. Reset the NVRAM Shut down your machine. Yes, a full shut down, not just logging out. […]
An optional in Swift is basically a constant or variable that can hold a value OR no value. The value can or cannot be nil. It is denoted by appending a “?” after the type declaration. An optional in Swift is basically a constant or variable that can hold a value OR no value. The […]
Increasing Productivity,Are you tired of always not being able to meet your deadlines? Do meetings scare you now? Is there anything you feel you need to change in your routine to put your best foot forward? Well, these are a few questions that all of us have asked ourselves at least once in our entire […]
Characters and Strings in Swift, A string is a series of characters, such as “hello, world”. Swift strings are represented by the String type. The contents of a String can be accessed in various ways, including as a collection of Character values.The syntax for string creation and manipulation is lightweight and readable, with a string […]
As a coder, you want to have a computer that makes your work comfortable. After all, you sit in front of a screen typing on a keyboard for eight or more hours every weekday, and it is not great for your health. The situation becomes even worse when you have extra worries about dealing with […]
