Flags not displaying value on first launch

[drekka]

We've noticed that on first launch after a fresh install of a settings app that uses Vexil, boolean flags display a toggle switch, but tapping it appears to do nothing. In actual fact the toggle is being changed, it's just the UI that is not working.

We've found that if we kill the app and restart it the toggles then work as expected and will continue to do so until we install the next version. Where upon they stop updating until we restart the app again.

Vexil version: 2.2.2
Swift version: swift-driver version: 1.75.2 Apple Swift version 5.8.1 (swiftlang-5.8.0.124.5 clang-1403.0.22.11.100)
Environment: Simulator and device.

Hi @drekka, this one sounds familiar, I believe we've seen it before. I will go digging through our PR history, but just to confirm, are you using UserDefaults to share your flags with your Settings app, or something custom?

Hi @bok- , I think I've faced the same issue too and solved it this way. But mine was slightly different again maybe. Will and I both solved that way the one we faced back then.

Hi, yes we are using a shared user defaults group. I'm also sure I read a mention of this somewhere but I was unable to locate it before writing up the issue.

Coming back to this one as I'm on another client's project where some other devs have implemented Vexil. Seeing the same issue with the UI. On first launch the flag toggles do not toggle even though the flag is set in the data. Getting it reported by users and it's quite annoying so would appreciate if it could be looked into soon :-)
