On-Device iOS Debugging in Xojo

You may or may not be aware that running iOS projects in the Simulator does not allow you to check all of your app’s features. There are a few features which rely on hardware capabilities which the Simulator cannot emulate. This can make it hard to track down bugs, and the only recourse is console logging. Starting in Xojo 2022r1 it’s possible to run your apps right on a physical device connected by USB.

Rubber Ducky, You’re the One

Yuck! It happens to everyone, from beginners to experienced developers: sometimes you’ll get stuck. Perhaps the code you’re working on just won’t do what you want or maybe you’re having trouble understanding code plucked from the internet. Talk to the duck. The rubber duck, that is. The term “rubber ducking” or “rubber duck debugging” is a software development technique where you explain the problem you are having to a rubber duck (or appropriate substitute). Often the act of explaining the problem to someone else, even if that someone is not real, can help you figure it out. It might be like inspiration struck.

Avoiding False-Positive Virus Detection in Windows Apps

Viruses continue to be a big problem on Windows. As a result, anti-virus software can be a bit over-zealous about detecting what it believes to be apps that have viruses embedded within them. We have had reports over the years that apps made with Xojo are sometimes falsely identified as being infected with a virus. This sometimes occurs because the 32-bit Xojo compiler puts executable code in a location where the anti-virus software doesn’t expect to find it. We’ve seen this occur even when users are debugging apps from the IDE. Fortunately in that case, there’s a fairly easy solution.
