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.

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

same for me EXC_CORPSE_NOTIFY Application Specific Information: ProductBuildVersion: 12E262 ASSERTION FAILURE in /Library/Caches/com.apple.xbs/Sources/DVTFrameworks/DVTFrameworks-18168/DVTITunesSoftwareServiceFoundation/App Loader/Wrappers/DVTITunesConnectApplicationVersionDescription.m:70 Details: (y) should not be nil.

I do use 16.0.1 downloaded inside IntelliJ.

it seems working in Xcode 12.5 but we do have a WORSE case. Suppose You need to write something like that: struct InfoSheetView: View {     if #available(iOS 15, *) {     } else {     } var body: some View { ..... } } even if an EMPTY if # I got: Expected declaration on if #.. I would like to write ..     if #available(iOS 15, *) { @Environment(\.dismiss) var dismiss     } else {     @Environment(\.presentationMode) var presentationMode     } see original example at: https://www.hackingwithswift.com/quick-start/swiftui/how-to-present-a-new-view-using-sheets and try to conditionally use @Environment(\.dismiss) var dismiss OR     @Environment(.presentationMode) var presentationMode

hello, processors AND chips are different so no way to do it. bootcamp relied on using same Intel chips, so some sort of HW virtualixzation was in place.

bootcamp does rely on Intel x64 binary instructions, and some sort of HW virtualisation, no way to run directly.

saame for me both on Monterrey (Xcode 13) AND Ventura (Xcode 14 beta)

a real, working example with a nice implementation is here: https://swiftuirecipes.com/blog/swiftui-scrollview-scroll-offset

same for me, and more stranger in Xcode 15 beta warning disappears... :(

fixed downloading xccode Version 15.0 beta 5 (15A5209g). God bless us! BUT... no tTest flight!! Unsupported Xcode or SDK Version. Your app was built with a version of Xcode or SDK that is not yet supported for upload to App Store Connect.

same for me, until Xcode beta 4 I could, but binaries crash on iOS 17 beta of yesterday. (opened another thread)

with very low stress, You can easy install directly with cable or wifi... or using Ad Hoc distributions (but require to register devices, create and "ad Hoc" profile, build IPA with those settings, and send them...
