Hawaii iOS Developer Meetup – Session 41

This meetup was a breeze. I’ve been creating SpriteKit games for a long time now and this was easy to talk about. I noticed that the mic had been disabled and only turned it on about 5 minutes into the stream. Please fast forward and you’ll hear the talking.

The most interesting thing that came up in this meetup was the discussion of collision bit masks for physics in the game. Leo asked a question about why the code was using an UInt32 variable for the physics category. I didn’t have the answer off the top of my head and asked Chae to explain. As he explained the solution, the issue grew wider and more complex.

Instead of talking abstractly, I brought out a whiteboard and asked Chae to write out what he was discussing. It was great to be able to see what he was only referring to in speaking.

Once we had a chance to discuss with the whiteboard, getting Leo in on the whiteboarding as well, we were able to reach a deeper understanding of why we would use an UInt32 to set the physics category for the SpriteNode’s Physics body.

No meetup next week. We will be meeting again on the 19th where we will be doing something new. I’m calling it Code Review. I envision developers bringing in their code for critique or help for a 20 minute block of time. Then we can collectively review and suggest solutions and improvements. This could get dicey and intimidating – and so what if it is. We’re gonna lean into it.

Please RSVP if you’re interested in attending the next meetup.

Hawaii iOS Developer Meetup – Session 40

This was a fantastic meetup! It really helps to do the tutorial 5 times so you don’t even have to think about it. There were no gaps in the talk and I felt very proud for giving it my best.

During this meetup I covered 2 tutorials.

The first tutorial covered setting up Unity, importing the ARKit plugin, and exporting the project from Unity to iOS, opening the project in Xcode, and building to the device.

The second tutorial covered setting up a cool animation to use 3d models and animations to create a hole in the ground that opens up in augmented reality that allows you to look inside of the hole with your iPhone.

Truth be told, I couldn’t get the project to compile before the meetup. There was a bug in the C# script that was being applied to the animation. Luckily, Chae got the meetup early and we paired on the problem. In 5 minutes we traced the bug, looked up the documentation, updated the function call with a generic type and the code compiled.

I am continually in awe of the power of pair programming. Four eyes are better than two 🙂

Next week I’ll be covering SpriteKit in Swift 4 to create 2d games. Please RVSP if you’re interested in attending the next meet up.

Hawaii iOS Developer Meetup – Session 39

This was a welcome change of pace. We had a significant number of new members attend this meetup. I took the temperature in the room by asking the attending developers who had had experience using ViewControllers before. Only 3 of the 10 hands went up. I shuffled the delivery of the talk on the spot and I think everyone learned something new.

During the talk I explained the connections between view controller code and view controller storyboards. I am noticing that developers from the web are increasingly getting interested in making the leap into iOS development. Good times 🙂

Once I finished discussing the basics of view controllers some of the developers had to leave (I had advertised the meetup as a 1 hour session). Since we extended the meetup format from 1 hour to 2 hours, a few of the regular developers and I had a chance to dive deep into programmatically unwinding a segue in a Navigation controller AND focus on sending a variable along with the unwind segue.

2 hour meetups is the way to go. I am excited to learn more and more with this new format.

Next week I’ll be covering Unity’s ARKit plugin to create augmented reality apps in Unity before porting them to iOS to use the ARKit features. Not really sure how to do this yet, but excited to research and present on Thursday. Please RSVP if you’re interested in attending!
