Xcode 26.4 quietly removed the ability to run app-hosted unit tests against physical iOS 16 devices, and Xcode 27 finally added a Delete Derived Data menu item — which the community correctly read as Apple admitting the IDE corrupts its own caches on a regular basis. Between those two announcements is the entire reality of…
How to escalate a stuck App Review or account flag when Apple Support goes silent
Your app has been stuck in “Waiting for Review” for ten days. You have filed three expedited-review requests and five support tickets. A “senior advisor” promised a callback two weeks ago and went silent. Meanwhile, the launch event you planned around your release date is next week. There is no official escalation path for any…
How to unblock a stuck notarization, fix Team ID prefix errors, and survive 3.1.1 review

Apple’s annual SDK cycle keeps shipping silent breaking changes. The UIDesignRequiresCompatibility plist key is honored on Xcode 26 builds and ignored on Xcode 27 builds. iOS 27 collapses iPhone horizontal size classes to compact, breaking ten years of storyboard constraint variations with no runtime warning. Reality Composer Pro 3 imports projects from RCP 2 with…
