Apple released the second RC (release candidate) for iPhone today, Friday May 21. The new update comes four days after the company seeded the first 14.6 RC to developers and public testers, and two days after the first beta for iOS 14.7.
Apple released this developer update just after 10 a.m. PDT, the company’s default release time for developer beta updates. If you’re a public beta tester for iOS, you should wait for Apple to release iOS 14.6 Public RC 2, which we expect today at 1:00 p.m. PDT or tomorrow at 10:00 a.m. PDT.
Release notes for iOS and iPadOS 14.6 RC 2
- The iOS & iPadOS 14.6 SDK provides support for developing apps for iPhone, iPad and iPod touch devices running iOS & iPadOS 14.6. The SDK ships with Xcode 12.5, available from the Mac App Store. For information on the compatibility requirements for Xcode 12.5, see Xcode 12.5 Release Notes.

SKAdNetwork: New Features
- Devices can now send installation validation postbacks to multiple ad networks that sign their ads with SKAdNetwork version 3.0. One ad network receives a postback with a parameter value of true for the ad impression that wins the ad attribution. Up to five other ad networks will receive a postback with the won value false if their ad impressions were eligible for the attribution but did not win it. (72917087)
Software update: new features
- You can now directly update your iOS or iPadOS device to the latest Release Candidate without removing the beta profile. After updating to the Release Candidate, you can choose to update to the next available beta or delete the profile to remove your device from the beta program. (66256273)
- Do not use the iOS MinimumOSVersion information property list key to indicate the minimum release of macOS in which your app is running. Instead, use LSMinimumSystemVersion. (73890473)
- Future releases of macOS will ignore the MinimumOSVersion key in Mac apps, including apps built with Mac Catalyst.
- Future releases of macOS will use the LSMinimumSystemVersion key in iOS apps built with Xcode 12.5 or higher. If an iOS app does not contain an LSMinimumSystemVersion key, future releases of macOS will compare the MinimumOSVersion of the app with the Mac Catalyst runtime version to determine compatibility.
How to download iOS 14.6 RC 2 on your iPhone
You need an Apple developer account to update your iPhone. You can get the recovery image from your dev portal and then install it using iTunes or Finder. Otherwise, install the configuration profile and then update it by going to Settings -> General -> Software Update. Finally, you can just wait for it to install automatically if you have a developer profile and “Automatic Updates” is turned on.
