As iOS 9's release approaches, Ionic developers must address several changes and bugs impacting their applications, especially those previously published for earlier iOS versions. Key issues include a window.location bug in UIWebView affecting Angular's browser location detection and a tilde CSS selector problem disrupting radio buttons, both requiring specific patches or updates. Additionally, iOS 9's new App Transport Security feature, blocking non-HTTPS traffic, necessitates adjustments in the development process for apps built with Xcode 7 and the iOS 9 SDK. While these issues do not affect mobile websites using iOS Safari or the new WKWebView environment, the imminent support for WKWebView in Cordova promises performance and feature enhancements for Ionic apps. The Ionic team plans to enhance their OS release testing to prevent future regressions, acknowledging that assumptions about iOS beta fixes did not hold true.
