How to work with Multi-Line String Literals in Swift

Submitted by matt_eaton on Sat, 06/03/2017 - 09:18 AM

With the release of Swift 4 next week and the implementation of proposal 168 now up and running in the Swift 4 toolchain I thought it would be nice to get in and get my hands dirty with multi-line string literals to provide some examples on how standard string manipulation practices now work with multi-line string literals in Swift 4. This tutorial will focus on some of the general operations developers use in working with and string manipulation for day to day tasks in development.

How to Find a Substring in a String with Swift

If you have ever wondered how to find a substring inside another string in Swift then hopefully this tutorial will help walk you through how to do that. As an example, in Swift 3 or above, if you have ever wondered how to determine if the substring "Agnosticdev," is part of the parent string "Hello Agnosticdev, I love Tutorials," then this tutorial will show you how to indicate, with a boolean value, the existence of the substring.

Looking ahead to the rollout of Swift 4 on Jun 5th at WWDC I have been scanning the Swift Evolution Github page to get a feeling of which of the proposals will make the cut for Swift 4 and which proposals will push ahead to later version of Swift 4.*.

The Swift Programming Language

How and why Swift started at Apple is still a bit of a mystery to the outside world and has been the focal point of many rumors and speculation over the years. If I had to pick one place where there is solid evidence of Swift’s roots at Apple, it would have to be with Chris Lattner. Chris Lattner is the internal founder of the Swift language at Apple, with a claim from Lattner on his personal website that the language dates back to 2010 internally at Apple.

A topic that I have been hearing a lot about lately is the MVVM design pattern. MVVM stands for Mode-View View Model and is intended to solve some of the concerns that have resulted from using the MVC design pattern - specifically in the context of iOS.

Swift Linked List Data Structure

Submitted by matt_eaton on Sun, 10/02/2016 - 01:24 AM

Today I was analyzing a potential bottleneck in some computation I was doing with Swift and thought I would try a basic linked list data structure to store data instead of an array. It soon dawned on me that I have never created a linked list in Swift before and thought this might be a good opportunity for a Swift Playground to test out my idea.

Last week I started building an iOS application in Swift 3.0 and Xcode 8 and was able to get a good portion of the application completed. Towards the end of last week I became aware of the need to integrate a Unity / Vuforia exported project into my existing iOS Swift project to enable an augmented reality feature in the iOS application I was working on.

Yesterday I was catching up on some of the recent proposals on the Swift Evolution Github page and seen a very interesting proposal that I thought I would discuss in brief detail.

Taylor Series In Swift

Submitted by matt_eaton on Sun, 08/14/2016 - 05:31 AM

The other day on Twitter I seen mention of the Taylor Series and it made me think back to calculus and how much I enjoyed the Taylor and Maclaurin series because learning about them was my first exposure into series and sequence approximations.
