Swift shortcut for returning and/or assigning the result of switch statement?
// Can currently do this
func titleForSection1(section: Int) -> String? {
switch section {
case 0: return "Foo"
case 1: return "Bar"
default: return nil
}
}
// But I want to do this to remove the redundant returns

Lists all fonts installed on iOS. Helpful to get the correct name when using custom fonts in an app 
func printFonts() {
    println("--- Installed fonts ---")
    let families = sorted(UIFont.familyNames() as! [String]) { $0 < $1 }

    for family in families {
        println("family: \(family)")
            
        let fonts = UIFont.fontNamesForFamilyName(family)
        for font in fonts {

Sample app to reproduce a ShareLink bug when used in a sheet with a confirmationDialog
import SwiftUI
// Sample app to reproduce ShareLink bug from a sheet
// 1. Run app, tap "Present Modal Sheet"
// 2. Try to Share from the sheet
// 3. It won't present and you'll see an error in the console:
// Attempt to present <UIActivityViewController: 0x102820000> on <_TtGC7SwiftUI19UIHostingControllerGVS_15ModifiedContentVS_7AnyViewVS_12RootModifier__: 0x102020e00> (from <_TtGC7SwiftUI32NavigationStackHostingControllerVS_7AnyView_: 0x103829a00>) which is already presenting <_TtGC7SwiftUI29PresentationHostingControllerVS_7AnyView_: 0x10202a800>.
// 4. Comment out the .confirmationDialog line and it works
// 5. Move .confirmationDialog before .sheet and it works
