Cannot connect to Github (Cannot pull or push) due to unexpected return value from ssl handshake -9806 (-1) Does anyone encountered this error?

Hello there,I'm desperatly trying to find the source code as mentioned from WWDC 19 swiftUI on watchOS talk.https://developer.apple.com/videos/play/wwdc2019/219/More specifically, I'm trying to write a custom flip card view but the fliped card give me a mirrored effect which is not what I desire.

When using SwiftUI's new TextEditor, you can modify its content directly using a @State. However, I haven't see a way to add a placeholder text to it. Is it doable right now? One example is the text input in Apple's own translator app. Which seems like a multiple lines text editor view that supports a placeholder text.

After the site update, I can no longer submit iOS app for review. Always show this error. An unexpected error was encountered when submitting for review. If the issue persists please contact us

If you look at Apple's PencilKit Sample, you'll noticed apple used a dataset file called Notes.dataset to save Pencilkit draws. Inside the Notes.dataset, it contains a general json file for Asset Catalogue.But more interesting, there is a file called color.drawing, which saves the actual data produced by Pencilkit. My question is, how do you create this file as a developer? For example, I want to create a tutorial using Pencilkit and save it as a ".drawing" file, to load up on first launch.
