As usual, some have had problems installing the Security Update. A tip was to try installing from a safe mode boot. (Security Update 2019-002 was released twice.)

FYI on Nvidia Web Driver Updates:
(There's been no Mojave Nvidia web driver updates yet, but a reminder to 10.13.6/10.12.6 users of Nvidia's web graphics drivers.) New OS updates or later build numbers after Security Updates typically break currently installed Nvidia web graphics drivers. I'd switch to the default Apple driver and reboot before updating, if your card is supported with the default drivers. If not, wait for a Nvidia driver update. (Some non-Mac EFI cards are not supported by default OS X drivers.)
As always, I post download pages for Nvidia web graphics driver updates in the news, and on the Video topics page when spotted.
(Update: Nvidia posted web graphics driver updates for the original (March 25th) release of Security Update 2019-002 for macOS 10.13.6 and 10.12.6. But the later builds in the revised Security Update 2019-002 required another update - see this April 2nd page with new drivers.)

• Apple Xcode 10.2 (for macOS 10.13.6 and later)

  - Debugger console has new frame variable command alias "v" that's faster than "p" or "po".
  - Playgrounds include stability improvements and additional memory safety checks.

• Download Swift 5 Runtime Support for Command Line Tools (3.2 MB)
  "Starting with Xcode 10.2, Swift 5 command line programs you build require the Swift 5 runtime support libraries built into macOS. These libraries are included in the OS starting with macOS Mojave 10.14.4. When running on earlier versions of macOS, this package must be installed to provide the necessary Swift 5 libraries. This package is not necessary for apps with graphical user interfaces."
  
  
• iOS 12.2 release notes
  (Long list of changes and fixes including Apple News+, changes to AirPlay, Apple Pay, Siri, Safari, Apple Music, 2nd gen AirPods support, plus security fixes.)

  includes general performance and stability improvements and these features:
  - Siri:* Ask Siri on your iPhone, iPad, or iPod touch to play what you want to watch on your TV, and control what's playing.
  - Apple TV Remote: With iOS 12.2, you can access the Apple TV Remote right from the Lock screen on your iPhone, iPad, or iPod touch. So you can easily play, pause, rewind, and control your Apple TV with just a tap.
