I found another solution. If you use Swift, you can set encoding with .isoLatin1 // codes let data = Data(base64Encoded: profileContent) let outputStr = String(data: data!, encoding: .isoLatin1) try outputStr?.write(to: saveUrl, atomically: true, encoding: .isoLatin1) it works fine in my application~

From security considerations, you should not connect to the remote database directly in the application.  If you are only locally stored, you can consider using a cross-platform RealmSwift.

**** YOU Xcode. Code-completion always gives an error selection

Like this, actually, it is will give me: viewDidLoad() instead of: override func viewDidLoad() { }

@zocario It's fine. But I got a new error, the XCFramework is embedded in the app as a dynamic library. Soooo, I can't upload app to App Store or export app to local. (error: exportArchive: Found an unexpected Mach-O header code: 0x72613c21)

Same problem! Xcode 12.2 macOS Big Sur 11.0.1

I ran into the same thing, which has now been resolved. Download xcframework.zip, then move it to the root of a package(any package) and use swift package compute-checksum.

I solved the problem, I think it was an xcode12 bug. Old Codes: extension UIWindow.Level { private static var statusBarRawValue: RawValue { UIWindow.Level.statusBar.rawValue } } New Codes: extension UIWindow.Level { private static var statusBarRawValue: CGFloat { UIWindow.Level.statusBar.rawValue } }

@DoxxerApple Yeah, this worked for me. But I would like to know why, after all, the whole module compilation is too slow.

@jlilest Yes, we cleaned up the build directory DerivedData, including using Xcode's Clean Build (Command + Shift + K, Command + Option + Shift + K), and we still get this error. This error is only available in Xcode 12 Release up to and including Beta.
