# TextViewBenchmark
A suite of performance tests for macOS text views
Every year, I check in on TextKit 2 to see how things are going. It was introduced in macOS 12, and I found it basically unusable. With macOS 13 it was better, but still rough. So far, on macOS 14, it seems like it might be ok! I was originally having some performance problems. So, I took some time to put together some automated performance tests.
## Usage
The tests are automated using XCTest's UI performance testing system, backed by custom `OSSignpost`. I find this really wonderful for both repeatibility and Instruments usage.
If you want to set up your own view for testing, you can do something like this:
```swift
static func withScrollableTextView() -> TextViewController {
let scrollView = NSTextView.scrollableTextView()
let textView = scrollView.documentView as! NSTextView
return TextViewController(textView: textView, scrollView: scrollView)
}
```
## Results
I'm using macOS 14 beta, so that may be a factor. Based on these tests, TextKit 1 is extremely fast and TextKit 2 actually even a small amount faster!
## Contributing and Collaboration
I'd love to hear from you! Get in touch via an issue or pull request.
I prefer collaboration, and would love to find ways to work together if you have a similar project.
I prefer indentation with tabs for improved accessibility. But, I'd rather you use the system you want and make a PR than hesitate because of whitespace.
