Apple hasn’t yet released iOS 13.4 to the public, but jailbreak tweak AppSync Unified is already updated to support it. That after the Checkra1n team added an experimental version of the jailbreak that supports the same iOS 13.4. That means that you should be good to go when Apple releases iOS 13.4 next week.
The update to AppSync Unified means that you can continue to use the tweak even after Apple releases iOS 13.4. If you’re familiar with the tweak that’s no doubt very good news indeed. And if you’re not, we’ll let the tweak’s developer explain what it’s all about.
AppSync Unified is a tweak that patches installd to allow for the installation of unsigned, fakesigned, or ad-hoc signed IPA packages on an iOS device.
AppSync Unified can be used to downgrade or clone installed apps, to download fakesigned IPAs (often emulators), and also to assist in the development of iOS applications using Xcode.
You can now download the updated version of AppSync Unified from your package manager of choice, ready for iOS 13.4. Apple is expected to announce the arrival of iOS 13.4 next week, adding support for new features and fixing bugs as it goes.
We’d definitely suggest updating, especially if the experimental Checkra1n support is working as anticipated. If it isn’t, well, you’d probably be best serviced by holding off for a little while!
