Implementing Handoff In iOS and macOS

Handoff is a neat feature that was introduced in iOS 8 and macOS (then OS X) v10.10. This capability allows an app to pass data across macOS and iOS devices so that a task started on one device can be completed on another device. In this tutorial we will implement Handoff on both iOS and macOS platforms.

Philly ETE 2017 #7 – The Swift Melting Pot – Daniel Steinberg

When the Swift programming language was released people argued about what sort of language it was. “It’s functional,” some argued and then criticized it for not being functional enough. “It’s OO,” others scoffed and then bemoaned the features they longed for from Objective-C. “It’s a Protocol Oriented language,” said Apple at the famous Crusty talk … Read More

Philly ETE 2017 #1 – Loving Lean Android Layouts – Huyen Tue Dao

Layouts are the foundation of Android UI, and while they are seemingly straightforward, understanding how to develop efficient layouts is sometimes less so. However, efficient, “lean” layouts can be vital to both user experience and app performance. This session examines the importance of lean layouts, tools for analyzing layouts and their performance, tips and techniques … Read More

Android Vector Graphics

I, like most developers, tend to rush into playing around with new technology. What I mean is you get excited when hearing or reading about something new then jump into the deep-end of the pool and while in mid-air throwing your towel to your chair. That’s what happened to me with VectorDrawable. I heard about … Read More

Philly ETE 2016 #18 – Mike Hartington – Ionic 2: Your First @App

Ionic has revolutionized the way web developers make the transition mobile development, but there’s always room to improve and make the lives of new app developers easier. With Ionic 2, we’ve improved upon much of what made Ionic 1 great, while also keeping things simple and reducing the fatigue that developers can feel when learning a new tool. We’ll introduce you to the basic Ionic 2 concepts and build an app live.

Philly ETE 2016 – Don Coleman – Building Wireless Sensors

Inexpensive wireless microcontrollers are everywhere. This session will look at building wireless sensors on a variety of hardware: the super low cost ESP8266, the Particle Photon and it’s cloud services, and the new Arduino MKR1000. In addition to building connected devices, I’ll discuss some options for collecting, storing, and visualizing the sensor data.

Philly ETE 2016 #5 – Andrea Falcone – Supercharging Your Mobile App Release with Fastlane

How would you like 2 extra hours of your time back every week? All mobile app developers face similar workflows as they work to upload an app to the App & Play Store. Many of these processes are currently done manually, but why not automate them? Fabric’s set of developer tools, collectively called fastlane, makes building, testing, and releasing your app faster, reproducible and less troublesome, leaving developers more time to focus on feature code and not deployment!

Philly ETE 2016 #1 – Donn Felker – Realm – a New, Easy to Use Mobile Database & Object Framework

So you need to store data in your mobile application? Great, now you need to work with SQLite. Writing SQL is great fun if you enjoy thinking about mapping your objects to a relational store over and over and over. But what if there was another solution? One that allowed you to work with objects and store them as such with a powerful query system. No transformations back and forth to a relational store. Well, you’re in luck, one does exist: Realm. Realm is a mobile object (MVCC) database that can do all of these things and more. In this session learn how you can rid yourself of SQL, SQLite and its binding chains so you can harness the power and speed of working with native objects in Realm.
