10 Best Design Principles of iOS app development?

Posted on by Jay

In the ever-evolving world of mobile app development, creating an iOS app that not only functions flawlessly but must also provide an exceptional user experience.

Users have come to expect intuitive and aesthetically pleasing interfaces, making design principles a fundamental aspect of iOS app development.

In this blog post, we will explore the key design principles that can help developers create user-friendly iOS apps that users love to interact with.

  1. Simplicity is Key

“Simplicity is the ultimate sophistication.” – Leonardo da Vinci

When it comes to app design, simplicity reigns supreme. Users should be able to navigate your app with ease, and clutter-free interfaces are more inviting.

Avoid overwhelming users with excessive features and elements. Keep the user interface clean, uncluttered, and intuitive.

Every screen should have a clear purpose, and the app’s functionality should be readily apparent.

  1. Consistency for a Familiar Experience

Consistency is the backbone of good design. Users should feel at home when using your app. Maintain a consistent design language throughout the app, including color schemes, typography, and layout.

Use standard navigation patterns like tab bars, navigation bars, and modal views to provide a familiar and intuitive user experience.

  1. Intuitive Navigation

Navigation is a critical aspect of an app’s design. Users should never feel lost or confused when moving through your app.

Implement clear and logical navigation paths, and ensure that users can easily return to previous screens.

iOS provides well-established navigation components, so make sure to use them effectively.

  1. Feedback and Responsiveness

Users need feedback to understand their actions’ outcomes. Implement immediate and meaningful feedback mechanisms, such as animations, tooltips, or progress indicators.

This helps users understand the system’s response to their interactions and reduces uncertainty.

  1. Accessibility for All

Accessibility is not just a design principle; it’s a legal requirement and a moral obligation. Make your app accessible to everyone, including users with disabilities.

Use accessible design elements, provide alternative text for images, and support VoiceOver for visually impaired users.

  1. Touch Targets and Usability

Design touch targets (buttons, links, etc.) with an appropriate size to accommodate different screen sizes and finger sizes.

A minimum tap target size of 44 x 44 points is recommended.

Ensure that the app’s elements are spaced adequately to prevent accidental taps and enhance usability.

  1. Loading and Performance Optimization

Users expect apps to be responsive and fast. Optimize loading times and overall iOS app performance.

Minimize unnecessary animations and use lazy loading for content. A snappy and efficient app is more likely to retain users.

  1. Error Handling and Clarity

Errors are bound to happen. When they do, your app’s error messages should be clear and helpful.

Guide users on how to resolve issues and avoid using technical jargon in error messages. Keep user frustration to a minimum.

  1. Orientation and Layout

Ensure that your app works seamlessly in both portrait and landscape orientations.

Design responsive layouts that adapt to different screen sizes and orientations, providing a consistent experience in all situations.

  1. User Testing and Iteration

Finally, no design is perfect from the get-go. Conduct user testing and gather feedback to identify pain points and areas for improvement.

Regularly iterate on your app’s design based on user feedback, evolving it to meet changing user expectations.

Learn How To Create An IOS App Development

Posted on by Sameer Mehta

Apple’s App Store had 2.184 million apps and games in 2022, an increase of 21.4% on the previous year. (source: businessofapps.com).

Newbies in the field of app development prefer to be iOS app developers for the following reasons:

  • Highly developed standards and practices
  • Better income/app revenues
  • Tech-savvy user base
  • Quality UX/UI
  • Safer enterprise development
  • Cloud integration/iCloud
  • Swift 5 and Swift Libraries
  • Faster migration to IoT apps

In 2023, Apple will open its latest store in the Battersea district of London, United Kingdom, adding to its 526 stores across 26 countries and regions.

But all that glory demands great efforts and for aspiring iOS app developers to taste the success promised by Apple’s growing tech fiefdom, a strong foundation must be laid in the form of solid practice and hands-on approach to coding and development.

If you’ve made it this far, we’d like to assume that you have some workable knowledge of the iOS app ecosystem. Even if you don’t, it’s not too late to get started.

Concept Idea and Research

A killer idea starts with identifying a problem or need. Create an app sketch with its components and dive into the market research process.

With thousands of apps being launched in the Apple Store daily, it’s likely that your idea may already have live applications. Develop strategies to incorporate new elements in your app that no other existing app offers.

Get suggestions from friends and/or app developers at the ideation stage to understand the user and expert feedback. If the stars align on all of the above, you have a winning app waiting to be made.

Technical Requirements

Get a Mac and an iPhone/iPad.

If that’s too much of an investment in new devices, get a couple of used pieces. Even if you don’t want to immediately purchase an iPhone/iPad, you can develop your app on the iOS simulator.

Install Xcode

Xcode is a free Integrated Development Environment that provides SDK (Software Development Kit) for Apple users. It’s used by beginners and experienced programmers.

You can start learning from a beginner’s manual. Start with your coding, debugging, configuring elements, and storyboard creation. You will need Xcode as it’s the only official tool for creating iOS apps and frankly, the only one you need.

Learn Programming

While you’re learning how to code for the iOS platform on Xcode, you could start learning Objective C, the old school program for C-based functions, and C APIs. However, Swift, Apple’s new open-source language is easier to learn and read, and almost all apps on Apple Store are migrating to Swift.

Learning both sides by side will give you unique advantages.

In fact, SwiftUI, a user interface framework, is Apple’s attempt to simplify coding even further (low code) where numerous lines of codes can be managed in simplified workflows and at a faster speed.

Even though it’s slated to be the future for app development, if you’re designing now, you need to learn UIKIT as existing codebases use it and it’s well supported since it’s been around for ten years.

Mock-ups and wireframes

Mock-ups are visual representations of your app while a wire-frame is the (un-clickable) structure of the app in black and white with simple lines and boxes.

There are dozens of helpful prototyping and mock-up tools available for iOS apps that offer easy to use drag and drop, shared user functionalities, let you add annotations and interactive mock-up designs with which the potential customers can interact.

App design

Below are the major factors you need to consider for your app design: one page should take you 4-5 days, longer if you’re a complete beginner.

  • Choosing the right artboard size as per screen sizes of different devices
  • Measuring the size of elements in points correctly
  • Figuring out page layout design, colors, themes, and styling by using sketch templates, including status bar, nav bar, tab bar, home screen indicator, etc.
  • Incorporating navigation and search within different pages
  • Text boxes, table views, buttons, content formatting, touch controls, resolution, alignment, distortion
  • Typography, caption styling, squircle, dark mode guidelines

Even as a beginner, if your strengths lie in development or programming, you can certainly think about outsourcing the design to a specialist.

While creating the actual UX/UI design, you’ll have to familiarize yourself thoroughly with Apple’s Human Interface Guidelines that let developers maintain standardized design and development rules for macOS, iOS, watchOS, and tvOS.

App development

This is divided into front-end and back-end development, the former for UX /UI, the latter for the app’s function with the server. Free online tutorials are widely available for every aspect of iOS app programming.

Understanding architectural design patterns for iOS should be on a developer’s radar for organized modules and seamless code with fewer bugs. One of the main functions of app architectures is to make code testability simpler.

Four common architectures are

MVC – Model View Controller, most commonly used architecture with View, Controller, Model Components

MVP – an improvement adds another main component- Presenter

MVVM – an evolved and trending architecture, Model-View-View Model

VIPER – is a clean architecture for iOS so that is simple and well suited for large projects.

As a beginner, you could consider starting with MVC and MVP and then upgrade to more complex architecture patterns.

It’s also recommended that you work in sprints (Agile Methodologies), dividing work into portions and then reviewing it for corrections before moving on.

Testing the app and deployment

Apple offers TestFlight Beta Testing before you release your app on the Apple Store. As a developer, you can invite testers to test builds and give feedback.

You’ll need to test your app to see if:

  • It installs quickly
  • Doesn’t crash too frequently
  • Launches all screens as expected
  • Is compatible with different iOS devices
  • Is secure and doesn’t leak data and information
  • It supports landscape and portrait modes
  • If it can go on sleep mode or send push notifications

You can actually test the app manually on a device or try open-source test automation frameworks. Make the required corrections and debug after testing.

If all’s well, you can apply to publish your app on the Apple Store. An annually renewable developer’s account costs $99.

However, you’ll have to comply with Apple’s restrictions on App Store Review Guidelines before your app can be published. For codesharing, version controlling and project collaboration, publish your code on GitHub.

Upgrades and Maintenance

You’ll have to consistently monitor app usage on analytics platforms, fix bugs and other issues as and when they arise, add new features and updates, and provide support for new and diverse hardware.

If you don’t update your app often, it loses its relevance and appears dead. The better the user experience, the less the uninstalls. In the long run, you can start to monetize your app (in case if you launch it as a free app in the beginning).

Even before getting started, it’s necessary that you scour the internet for research on the tutorials and guides and get advice from experts or experienced developers who can guide you practically throughout the process.

Finally, patience and perseverance will be your best allies as an app developer.

How To Enhance Image Processing With Core Image In IOS Apps

Posted on by Jay

Core Image is a powerful framework for image processing and analysis technology designed to provide real-time processing for still and video images. This helps you easily apply filters to images, such as modifying the hue, exposure or vibrant. It uses the GPU or CPU rendering path to process the image data very fast.

Core Image can be chained with multiple filters to an Image or video frame at once by creating custom effects. Core Image provides us more than 90 built-in filters on iOS and over 120 on OS X. You can set up filters by supplying key-value pairs for a filter’s input parameters. You can use the output of one filter as the input of another filter, to create amazing effects.

Here is how the Core Image is related to the iOS operating system

core-image-1024x415

Before going into Core Image, let’s know about the classes used in the Core Image framework:

CIContext:

The CIContext is a class which provides an evaluation context for rendering a CIImage object. CIContext class is used to take advantage of the built-in Core Image filters while processing an image.

CIImage:

The CIImage is a class which represent an image or holds an image data which may be created from a UIImage, from an image file, or from pixel data.

CIFilter:

The CIFilter class produces a CIImage object as output. A filter takes one or more images as input. The filter class has a dictionary that defines the attributes,so the parameters of a CIFilter object are set and retrieved through the use of key-value pairs. This helps us to add some beautiful effect on the input image.

Sample example:

In this example local image path is used in resource file to apply effects.

// 1 Retrieving the localimage.png path from resource bundle

NSString *filePath =
  [[NSBundle mainBundle] pathForResource:@"localimage" ofType:@"png"];
NSURL *fileNameAndPath = [NSURL fileURLWithPath:filePath];

// 2 Converting the normal image to CIImage object by passing the URL of original localimage.png

CIImage *beginImage =
  [CIImage imageWithContentsOfURL:fileNameAndPath];

// 3 Adding the filter SepiaTone effect to the localimage.png

CIFilter *filter = [CIFilter filterWithName:@"CISepiaTone"
                              keysAndValues: kCIInputImageKey, beginImage,
                    @"inputIntensity", @0.8, nil];
CIImage *outputImage = [filter outputImage];

// 4 showing the output image in the UIImageView

IImage *newImage = [UIImage imageWithCIImage:outputImage];
self.imageView.image = newImage;

Note : Here we can change the value of the CIFilter value which is given 0.8 by using a slider which min value is 0 and max value is 1.

Here we have not used the CIContext to perform an CIFilter as said earlier. It helps us to make it easier.

Lets change the above code to include the CIContex:

CIImage *beginImage =
[CIImage imageWithContentsOfURL:fileNameAndPath];
 
// 1
CIContext *context = [CIContext contextWithOptions:nil];
 
CIFilter *filter = [CIFilter filterWithName:@"CISepiaTone"
keysAndValues: kCIInputImageKey, beginImage,
@"inputIntensity", @0.8, nil];
CIImage *outputImage = [filter outputImage];
 
// 2
CGImageRef cgimg =
[context createCGImage:outputImage fromRect:[outputImage extent]];
 
// 3
UIImage *newImage = [UIImage imageWithCGImage:cgimg];
self.imageView.image = newImage;
 
// 4
CGImageRelease(cgimg);

Let’s see what happened here:

Here we set up the CIContext object. The CIContext takes an NSDictionary that specifies options including the color format and whether the context should run on the CPU/GPU. Here the default values are fine and so you passed as nil for that argument.

Here we used an method on the context object to draw a CGImage. Calling this method createCGImage:fromRect: on the context with the supplied CIImage will give us an output as CGImageRef.

Next, we converted the CGImage to UIImage using “imageWithCGImage”.

At last we release the CGImageRef as CGImage. CGImage is a C API which need to free memory even it runs with ARC.

Note: To know about all available filters write the following code and call the method in viewDidLoad / onLaunch. The filters are written on the console log.

-(void)logAllFilters {
NSArray *properties = [CIFilter filterNamesInCategory:
kCICategoryBuiltIn];
NSLog(@"%@", properties);
for (NSString *filterName in properties) {
CIFilter *fltr = [CIFilter filterWithName:filterName];
NSLog(@"%@", [fltr attributes]);
}
}

How To Make Static Framework IOS Device Independent?

Posted on by Jay

In our previous post, we had mentioned the steps to create a Static Library or Framework for iOS. Here, we will illustrate the steps to make it device independent, i.e. the library can be used to develop app for all iOS devices, instead of recreating the code for each device.

Step 1: Create an Aggregate Target

  • Click File >> New Target and create a new Aggregate target in Other menu.

  • Name your aggregate target – like ‘Framework’

xcode_image

 Step 2: Adding the Static Library as a Dependent Target

  • Add the static library target to the ‘Target Dependencies’.

framework-image

Step 3: Build the ‘Other’ Platform

  • To build the ‘Other’ platform, use a ‘Run Script’ phase.

  • Add a new ‘Run Script’ build phase to your ‘Aggregate’ target and paste the following code.
set -e
 
set -e
 
set +u
 
# Avoid recursively calling this script.
 
if [[ $SF_MASTER_SCRIPT_RUNNING ]]
 
then
 
   exit 0
 
fi
 
set -u
 
export SF_MASTER_SCRIPT_RUNNING=1
 
  
 
SF_TARGET_NAME=${PROJECT_NAME}
 
SF_EXECUTABLE_PATH="lib${SF_TARGET_NAME}.a"
 
SF_WRAPPER_NAME="${SF_TARGET_NAME}.framework"
 
  
 
# The following conditionals come from
 
# https://github.com/kstenerud/iOS-Universal-Framework
 
  
 
if [[ "$SDK_NAME" =~ ([A-Za-z]+) ]]
 
then
 
   SF_SDK_PLATFORM=${BASH_REMATCH[1]}
 
else
 
   echo "Could not find platform name from SDK_NAME: $SDK_NAME"
 
   exit 1
 
fi
 
  
 
if [[ "$SDK_NAME" =~ ([0-9]+.*$) ]] then
 
   SF_SDK_VERSION=${BASH_REMATCH[1]}
 
else
 
   echo "Could not find sdk version from SDK_NAME: $SDK_NAME"
 
   exit 1
 
fi
 
  
 
if [[ "$SF_SDK_PLATFORM" = "iphoneos" ]]
 
then
 
   SF_OTHER_PLATFORM=iphonesimulator
 
else
 
   SF_OTHER_PLATFORM=iphoneos
 
fi
 
  
 
if [[ "$BUILT_PRODUCTS_DIR" =~ (.*)$SF_SDK_PLATFORM$ ]]
 
then
 
   SF_OTHER_BUILT_PRODUCTS_DIR="${BASH_REMATCH[1]}${SF_OTHER_PLATFORM}"
 
else
 
   echo "Could not find platform name from build products directory: $BUILT_PRODUCTS_DIR"
 
   exit 1
 
fi
 
  
 
# Build the other platform.
 
xcodebuild -project "${PROJECT_FILE_PATH}" -target "${TARGET_NAME}" -configuration "${CONFIGURATION}" -sdk ${SF_OTHER_PLATFORM}${SF_SDK_VERSION} BUILD_DIR="${BUILD_DIR}" OBJROOT="${OBJROOT}" BUILD_ROOT="${BUILD_ROOT}" SYMROOT="${SYMROOT}" $ACTION
 
  
 
# Smash the two static libraries into one fat binary and store it in the .framework
 
lipo -create "${BUILT_PRODUCTS_DIR}/${SF_EXECUTABLE_PATH}" "${SF_OTHER_BUILT_PRODUCTS_DIR}/${SF_EXECUTABLE_PATH}" -output "${BUILT_PRODUCTS_DIR}/${SF_WRAPPER_NAME}/Versions/A/${SF_TARGET_NAME}"
 
  
 
# Copy the binary to the other architecture folder to have a complete framework in both.
 
cp -a "${BUILT_PRODUCTS_DIR}/${SF_WRAPPER_NAME}/Versions/A/${SF_TARGET

Step 4: Build to verify

  • Now  you have set up an environment to build a distributable <project_name>.framework

  • Build the ‘Aggregate’ target

  • Expand the Products group in X-Code, right click the static library and click ‘Show in Finder’

Note: If this doesn’t open Finder to show the static library, then try opening

~/Library/Developer/Xcode/DerivedData/<project name>/Build/Products/Debug-iphonesimulator/.

  • In this folder you will find your <project_name>.framework folder.

You can now share the <project_name>.framework among other iOS app developers.
