A new open-source tool called simless has been developed to significantly speed up the UI testing process for coding agents working on iOS applications. Traditional methods involving booting a separate iOS Simulator for each agent are slow and resource-intensive, taking around 22 seconds per check and consuming gigabytes of RAM. Simless, however, runs the actual app natively on Apple Silicon as a headless host, allowing for much faster compilation and hot-patching of UI changes in approximately 2 seconds. It provides UI feedback as an accessibility tree rather than a screenshot, further reducing processing time and identifying issues like unlabeled controls or small tap targets. AI
