iOS App Development Programming Languages

Swift

Swift is an open-source general-purpose programming language that has been growing fast since it was announced in 2014. It is the official language for iOS and is designed to be easy, fast, and safe. Swift is known for predictable and consistent performance, offering modern features and concise syntax.

Together with Xcode, Swift makes programming powerful. It is hosted under the Apache 2.0 license, and its source code is hosted on Github. It is used on all Apple platforms and integrates with Xcode developer tools. You can migrate Objective-C into Swift. You can start learning by visiting the Swift Playgrounds.

Objective-C

Objective-C was Apple’s primary programming language until Swift succeeded it in 2014. Objective-C is a superset of the C, general purpose with object-oriented capabilities. Objective-C files can coexist with Swift in a project. You can Import APIs, use runtime features, or migrate code into Swift.

Krasamo can modernize your Objective-C codebase and migrate to Swift by replacing pieces gradually and avoiding rewriting the entire code at once. Migrate code by classes and replace them with Swift files, making sure to understand how Swift translates Objective-C features. Also, keep a close eye on the native Swift syntax, customize interactions with Objective-C APIs (macros, selectors, paths), add nullability to control declarations, language interoperability, handling methods, objects, types, functions, etc.                                                 

iOS 15 SDK Key Technologies

1

SharePlay for Developers

2

Focus and Notifications

Communicate important information to your users by generating user-facing notifications from your app (local) or from a managed server (remote). Local notifications triggers delivery by the apps for certain triggered conditions. For remote notifications use Apple push notification service (APN).

3

ARKit

Create Augmented reality (AR) experiences for specific cities and landmark locations anchored to geographic coordinates. Also, supporting improved motion tracking and face tracking features extended to the front-facing camera. Other AR features enable placing virtual objects in their physical surroundings and detection features.

Safari Web Extensions
Create Safari web extensions for customizing and enhancing browser functionality using HTML, CSS, and JavaScript. Use Xcode to repackage extensions to work with other browsers and provide a secure distribution through the App Store and usage model by implementing them as iOS or macOS.

10

ShazamKit
ShazamKit is a framework for audio recognition that finds an audio match using an acoustic signature that captures the audio signal and generates and stores a reference signature with metadata. A query signature matches the catalog of reference signatures captured, creating functionality for music recognition and virtual learning products.

11

MusicKit
MusicKit framework for integrating Apple music into your app or website. Your app can fetch music from the Apple Music catalog using a request feature, allowing filters to load items, work with music attributes and notification messages, set value types, and playback support.

12

Healthkit
The HealthKit framework allows you to access and share data with your app, acting as a central repository of data. Your app can use HealthKit features and focus on custom features, giving users the freedom to pick any device and centralize information from various apps.

13

HomeKit
HomeKit is a framework that allows to use your app to connect smart home automation accessories. HomeKit provides a user-focused interface to coordinate and control accessories. Enabling HomeKit in your app provides seamless connectivity with Matter accessories and third-party home hubs.

14

CloudKit
CloudKit is a framework that stores app and user data in iCloud and synchronizes across devices and platforms. Apps are organized in containers that include databases and siloed app data, information separated by access type or function, and encryption and privacy protection.

15

EventKit
EventKit framework lets you add calendar and reminders to your app, set up alarms, recurring events, and notifications integrated with the user’s events. Your app accesses the users’ calendar events and supports the creation of new events.

Machine Learning Models in iOS App Development

Create ML

Create ML is a Swift framework for building and training ML models with the purpose of integrating them into your apps. A model can be created and trained using Create ML in Xcode or it can be created with other libraries and then converted to Core ML format (models with an .mlmodel file extension).

 

Using Core ML

Your new iOS App can train or improve a Machine Learning model from the data on the user’s device. A model is trained and retrained—or updated—with data from the device and is then used for making predictions. Common data for implementing ML models with Core ML are voice, text, video, and audio files.

Core ML API connects your app and the Machine Learning models inside the device, optimizing responsiveness and keeping data private. Models must be encrypted at compile time.

There are repositories of open-source trained models in frameworks such as TensorFlow and Pytorch. Training libraries and third-party models can be converted to Core ML using Core ML Tools.

A team of experienced Krasamo developers can build and run a Core ML App and integrate a model into your App, as well as create custom workflows or advance use cases.
