macOS - UserDefaults is different in Swift and Terminal

I'm trying to access a system preference (com.apple.menuextra.clock DateFormat specifically) from my Swift app using UserDefaults. Using terminal, defaults read com.apple.menuextra.clock returns



{

    DateFormat = "EEE MMM d  h:mm:ss a";

    FlashDateSeparators = 0;

    IsAnalog = 0;

}


However, if I do this in my Swift app



print(UserDefaults.standard.dictionary(forKey: "com.apple.menuextra.clock"))


I get nil.



How do I access this in Swift? If it helps, I'm only looking for DateFormat so I know if the user prefers 12- or 24-hour time. I've tried 



DateFormatter.dateFormat(fromTemplate: "j", options: 0, locale: Locale.current)!


then finding whether or not it contains a, but that doesn't work either.



Thanks in advance.

          You were not searching in the right domain. When you call dictionary(forKey:), bool(forKey:), integer(forKey:), etc, you are searching through a hierarchy of domains:





          • NSArgumentDomain: the arguments that are passed to your app when it starts.

          • Application domain: the keys that you defined in your app.


          • NSGlobalDomain: system-level preferences.

          • Languages: system-level preferences that are dictated by the user's choice of language.


          • NSRegistrationDomain: temporary keys that your app define. Must be re-registered every time your app launches. If you want it to stick, use the Application Domain.


          com.apple.menuextra.clock is not a key in the hierarchy above. It's a domain by itself (think of it as a separate app with its own preferences). Use this instead:



          if let dict = UserDefaults.standard.persistentDomain(forName: "com.apple.menuextra.clock") {
          
    print(dict)
          
}

          Can a sorcerer learn a 5th-level spell early by creating spell slots using the Font of Magic feature?

          Image
          28 6 $begingroup$ Per the Font of Magic feature, sorcerer can use Flexible Casting to create 5th-level spell slots at level 7, even though they are not typically available until level 9. You can transform unexpended sorcery points into one spell slot as a bonus action on your turn. The Creating Spell Slots table shows the cost of creating a spell slot of [5th level is 7] If such a sorcerer levels up while still having this 5th-level spell slot, can they choose a 5th-level spell as the spell they gain upon levelling up? The Spellcasting feature states: Additionally, when you gain a level in this class, you can choose one of the sorcerer spells you know and replace it with another spell from the sorcerer spell list, which also must be of a level for which you have spell slots.

          Does disintegrating a polymorphed enemy still kill it after the 2018 errata?

          Image
          up vote 13 down vote favorite 1 After the 2018 errata, the disintegrate spell description now reads: A creature targeted by this spell must make a Dexterity saving throw. On a failed save, the target takes 10d6 + 40 force damage. The target is disintegrated if this damage leaves it with 0 hit points. If you were to polymorph an enemy into a rat and then disintegrate it, would the enemy be disintegrated or would it just return to its original form?

          A Topological Invariant for $pi_3(U(n))$

          Image
          3 3 $begingroup$ Recently, I saw a construction of topological invariant for $pi_3(U(n))$ with $ngeq 2$ : $$ N=frac{1}{24pi^2}int_{S^3} d^3x epsilon^{ijk} Tr[(U^{-1}partial_{x_i}U)(U^{-1}partial_{x_j}U)(U^{-1}partial_{x_k}U)] , $$ where $Uin U(n)$ depends on $boldsymbol{x}=(x_1,x_2,x_3)in S^3$ , $epsilon^{ijk}$ is the Levi-Civita symbol, $i,j,k=1,2,3$ , and the duplicated indexes are summed over. It is claimed that $N$ is an integer, but why? Update 02/02/2019 I think I got an argument for $n=2$ . In this case, $U=e^{i varphi} q$ with $qin SU(2)$ . Due to the trace and the Levi-Civita symbol in $N$ , $varphi$ does not contribute to $N$ . As $Tr[q^{dagger}partial_i q]=0$ and $(q^{dagger}partial_i q)^{dagger}=-q^{dagger}partial_i q$ , $q^{dagger}partial_i q$ in geneeral has the form $q^{dagger}partia
