In a Bloomberg article mentioned in the latest TidBITS:
...Apple executives hope that the overhauled testing approach will improve the quality of the company’s software over the long term. But this isn’t the first time that Apple engineers have heard this from management.
Last year, Apple delayed several iOS 12 features — including redesigns for CarPlay and the iPad home screen — specifically so it could focus on reliability and performance. At an all-hands meeting in January 2018, Federighi said the company had prioritized new features too much and should return to giving consumers the quality and stability that they wanted first.
Adam's closing remark:
We hope Apple’s new testing procedures will make things better, but we’re reserving judgment until iOS 14 ships.
This re-commitment to quality is said to apply to
all operating systems including macOS.
