Web Push Notifications for iPhone and iPad - Apple iOS?
Apple still hasn't added support for Service Workers on iOS as of now with the latest iOS 11 beta. So, for now, web push notifications are still not supported on the iPhone or the iPad. Last time we had heard that WebKit will be bringing support for Web Push to iOS within a few years at their Contributors conference back in 2015. It has been 2 years since then, and the task is still listed as under consideration.
Web Push has made its way to all browsers, and even Apple has added support for Safari on the Mac but not on iOS. We are hopeful that Apple will add support for the API soon on its mobile platform, and marketers would have far better reach with the inclusion of iPhones and iPads to the mix.
