A fifth and likely final beta build of iOS 11.4 arrived yesterday for those who are in the Apple Beta program. The update doesn’t bring any new features to the platform other than what has already been discussed but does bring a few fixes.
The update weighs in at 2.2GB, indicating that this is the full build and is likely a release candidate build. For those new to beta testing, release candidates are generally the build that a developer wants to release as the general availability (GA) release. In other words, they feel their work is done and barring a show stopping bug being found, this should be the build everyone sees when 11.4 is released.
