Remembering the uproar when Apple said 3rd party apps would have to be web apps, but didn't ship the features needed to write good web apps on the first iPhone? The term PWA wasn't coined until 8 years later, and Apple has long been accused of hobbling its web stack to incite people to ship on the App Store and pay their 30% tithing.
The term PWA may not have been coined until 2015, but you could definitely save a webpage to your home screen on i(Pad)OS at least as early as 2010. Granted, it was pretty limited, but you could put an icon on your screen, have it open a web view that was somewhat separate from Safari, store data with localstorage, and generally look and feel kinda mostly like a native app.
