Thanks for your PR!

With the rise of SwiftUI this package already felt a little too late to the party when I first released it a few years ago :). I haven't really looked at it since the last release, since I had no issues with it. I'm glad you did!

I took a quick glance at your changes. I noticed a few things:

  • You might want to mention in the readme that older iOS/tvOS versions are supported when using version 1.3
  • The most left shield image doesn't seem to work
  • I'm not too sure about removing the screenshots from the readme. I know the current ones aren't great though. Having somethings visual does make it more appealing and clear for some people. Maybe you can ask your coworkers about this.
  • Has the actual detection algorithm changed at all? I couldn't really find it but maybe I should study it some more.

I actually have an idea for a new feature that I never got around to. When you try to present a VC from a VC that is already presenting another VC you get a warning in the console, but no crash or anything (just nothing happens). This is easy to overlook. This often causes certain alerts to just not show, and sometimes even memory leaks. The idea is that the detector catches this and shows you a warning dialog (with screenshot of the failed VC and orange tinted background) when this happens. For release builds you can log when this happens (just like with memory leaks). Just swizzle the present method and check for presentedViewController. Let me know if you like to give this a try.

I'll study the changes some more when I have time.

Again thanks for your PR. However I looked at the diffs and I'm struggling to find changes that reflect some of your claims:

  • Enhanced error handling and edge case management
  • Improved memory leak detection algorithms
  • Enhanced detection mechanisms for UIViewController and UIView leaks
  • Better handling of complex view hierarchies
  • Improved accuracy with fewer false positives
  • Enhanced ignore lists for specific classes
  • Optimized detection algorithms

Am I overlooking something, or is this something you want to work on in the future perhaps?
