previous link is broken  macOS Big Sur 11 Beta 3 Release Notesfor 62986286. any other info available? THX

Apart form very good Apple materials, I onesti think without a serious CS college course. the task is vey hard: too many concepts You can only undestand after a graduation.

Swift see at: https://developer.apple.com/forums/thread/652667?answerId=618217022&page=1#622923022

my 2 cents for swift: // swift implementation of ADC call let NATIVE_EXECUTION        =  Int32(0) let EMULATED_EXECUTION      =  Int32(1) let UNKONWN_EXECUTION       = -Int32(1) func processIsTranslated() ->Int32 {     var ret = Int32(0)     var size = ret.byteWidth 	  let result = sysctlbyname("sysctl.proc_translated", &ret, &size, nil, 0)     if result == -1 {         if (errno == ENOENT){             return 0         }         return -1     }     return ret } func processIsTranslatedStr() -> String {         switch processIsTranslated() {         case NATIVE_EXECUTION:             return "native"         case EMULATED_EXECUTION:             return "rosetta"         default:             return "unkown"         } } ```     

a bit in late.. but for next people... I do calc let index = col + row * self.MaxCols outside, otherwise I got your message.    let gr = GeometryReader { (geometry : GeometryProxy) in             VStack() {                 ForEach(0..<self.MaxRows) { (row: Int) in                     HStack {                         ForEach(0..&lt;self.MaxCols) { (col: Int) -&gt; GridCellView in                             let index = col + row * self.MaxCols                             return GridCellView(                                 w: (geometry.size.width / CGFloat(self.MaxCols)) - 25, // compensate inset..                                 titleAndText: firstLevelQuestions[index],                                 room: self.room,                                 troubleShootings: troubleShootings[index] )                         }                     }                 }             }             

I read in late, but I can say1) set to Yes if You are going on Apple Store(read here soem idea.. https://www.infoq.com/articles/ios-9-bitcode/ )2) I used it in enterprise dev, too: For final user is he same.(for quick enterrpise dev. for example is fster to leave it off, but is mainsly to save exporting time..)

OSX catalina: dialog.isAccessoryViewDisclosed = true

a bit late, but hpe can help1) ln ..does not work any more in Catalina2) mysql lib are newer.. with less bugs but as always bad....so ...https://stackoverflow.com/questions/17465902/use-of-external-c-headers-in-objective-c/60130956#60130956

so the way is plist, not entitlements....

wait.. adding to PLIST or Entitlements?I added to plist and seems to work, but docs state we must add to entitlements...
