I'm back to working on my iOS game "Slide Tilt Roll" in preparation to using it for a presentation to some computer students at my son's high school.

I updated the MacBook to High Sierra, updated to XCode 9, installed XCode 8 to upgrade the code base from Swift 2.2 to Swift 3.0, then used XCode 9 to bring it up to Swift 4.0. That worked for 90% of the code, then I needed to go through and manually fix a few errors and warnings (mostly confined to sqlite and CGPath functions).

I've also tweaked the launch and main page backgrounds to display better on the iPhone X - I wonder if I can use one of them at the Apple Store for a quick test

The next big thing is to add sound effects and music. I've found a paper for some algorithmically generated music which will I will hopefully be able to use.

I'm still looking for anyone willing to create levels to supplement the ones I have created programatically.

Interested? You need an iPhone, iPad or iPod Touch running iOS 9 or later (configured to send email) and a willingness to create levels gratis for my 100% free application.

In order to install my app I need the UDID for your device. This can be obtained from iTunes by clicking on the Serial Number on the device Summary panel, then right clicking on the hex digit string, selecting copy, and sending it to me via PM. (If you don't have iTunes, you can get it by plugging into a computer and looking at the USB device information. Ask, and I'll provide instructions. Any other methods (websites, apps) are either outdated or extremely suspect.) After I get your UDID I will update my Apple Developer account device list and send you the link to download and install.

Muchas gracias

Merci beaucoup
