    Call Twilio Functions from iOS in Swift callfuncsfromios.jpg

    There are many things you can do from iOS but sometimes, for example, you may need to make a web request to fetch information. With Twilio Functions you can focus on writing the code that matters without having to maintain a server. This tutorial will show you how to set up a Twilio Function that returns a Pokemon joke or two and then call that Function from an iOS application.

    Setup

    Before you get started, you'll need

    • a Twilio account to create a Twilio Function 
    • Xcode installed to make a rudimentary iOS app to call the Function
    • A little JavaScript (for Twilio Functions) and Swift knowledge

    Make a Twilio Function 

    The Twilio Function in this tutorial will return a simple hard-coded Pikachu joke. To make that Function, from your Functions page, click the red "+" button to make a new Function.redplusfunc.png

    If this is your first Function, you'll click …

    Generate Songs with Markov Models using Server-Side Swift, Perfect, and Twilio SMS generate-music-with-swift-twilio

    I like music and coding and one way to make music with code is by predicting words and generating a new song. You can do this with Markov models, as introduced in this last Twilio blog post. Now let's learn how to train a model on a .txt file to generate a song and then generate another song or text via Twilio SMS with server-side Swift and Perfect.

    Set Up

    To code along with this post you should have the following:

    1. A Twilio account to buy a phone number
    2. ngrok, a tool for putting the app running on your local machine on the web
    3. Xcode

    First, make a new Single View project in Xcode and run pod init on the command line in the directory where your Xcode project exists to create a Podfile in order to install the Markov Model library via CocoaPods, as further …

    Receive and Respond to Text Messages with Server-Side Swift, Perfect, and Twilio perfecttwilioswift.jpg

    Perfect is a versatile open source server-side Swift framework and toolset that makes it easy for developers to quickly create server- and client-side apps. Let's see how easy it is to send SMS with Twilio and Perfect.

    Setup

    To follow along with this post we'll need

    Install Perfect using the Swift Package Manager. Create a new project directory called PerfectSMS and then on the command line in your project directory, run

    swift package init --type executable
    swift package generate-xcodeproj
    

    This generates a package with the same name as your current directory.

    1. Package.swift at the top-level of your project contains your package description and your package’s dependencies.
    2. Sources/ is home to all your Swift source files, including main.swift, which will be the entry point for your project. It currently prints hello, world to the Terminal.
    3. Tests/ will contain unit tests you can write …

    How to Add Keyframe Animations to iOS Apps in Swift 4 OibP_MhVytCwAouP1CsLwizQPWxk1cSLY46NM69XDz2GyYJ3ddBQOBfAzWu-i3dU-CAjYUO2AbG5dTSJL6ZjW9t2cVkD05fO8c4tbb5kTuLdYoTZi9r8NQy5V1svA1SzWwtm6Q81

    In the beautiful world of modern iOS applications, not much stands out more than well applied animations and transitions. They capture the user’s attention and set your app apart from the competition. If you’ve ever wished to add cool animations to your current or future projects but felt it was too challenging, this article is purposely meant to change your mind.

    Tools You’ll Need

    To be able to follow along with this tutorial, there are a couple of prerequisites before we start. You will need:

    • A Mac running the latest point release of macOS X Sierra or later.
    • Xcode 8 or later.
    • Basic knowledge of the Swift 4 language and Auto Layout.

    Getting Started

    Now that we have all that we’ll need, let’s find out what we’re going to be working on.
    I have already set up a small project for us to work on. You can download it …

    Intro to Markov Models with Swift Rick Roll Cover Image

    Did you know PageRank, the algorithm Google uses to determine the order of search results, is a type of Markov chain? I first learned about Markov chains and Markov models in my Speech Synthesis and Recognition elective and was amazed at how they are used in speech recognition, music generation, and modeling sequential data to predict the outcome of a basketball game (or almost any competition.)

    What are Markov Chains and Markov Models?

    The most basic type of Markov model is a Markov chain, a model whose next state is only selected based on its current state. Markov chains are used in genetics, finance, economics, game theory, and other fields. An example of one would be predicting tomorrow's weather by looking only at today's weather, not yesterday's.

    Wikipedia defines a Markov model like so: 

    In probability theory, a Markov model is a stochastic model used to model randomly changing …

    Intro to Speech Recognition in Swift via FlyoverKit speechsiricombined.jpg

    One of my favorite computer science electives was Speech Synthesis and Recognition because Natural Language Processing and Computational Linguistics are becoming more widespread (look at Siri!). In this post we will add speech recognition to select famous landmarks with FlyoverKit in Swift. If you haven't seen part one of this multi-part series, check it out on the Twilio blog here.

    Setup

    For this post you will need Xcode 10, a Mac, and a physical iOS device to test the speech recognition features. To follow along with this post make sure to clone the corresponding GitHub repo here as we'll be adding speech recognition capabilities to it. If you just want to make a simple speech recognition app in Swift, you can use the same code but just need to add a button to your ViewController. Name the button locButton, and create a label called placeLbl …
