• Specify $(TeamIdentifierPrefix)group.com.onmyway133.MyApp

• $(TeamIdentifierPrefix) will expand to something like T78DK947F3., with .

• Then using is like a normal UserDefaults

let defaults = UserDefaults(suiteName: "T78DK947F3 .group.com.onmyway133.MyApp")

defaults?.set(true, forKey: "showOptions")
defaults?.synchronize()
