I'm brand new to iOS app development with Xcode and am getting this error message and can't even compile/run my extremely basic app. I'm trying to work through Angela Yu's course on Udemy and keep running into this error. I'm using Xcode 12.4. I went to my project in the Finder and it says I have read/write permissions for the file, so I'm really confused as to why I keep getting this error. I saved my project inside of a folder called iOS/Swift Udemy. I have built other simple apps and been able to run them in other folders, so I'm just really confused as to why this isn't working. I've read multiple forums regarding the topic and none have helped me alleviate this issue, so I was hoping someone could help me out here. As aforementioned, I'm a beginner so any type of complex/detailed/complicated answer is probably going to go right over my head. I'm sure I have some type of basic error going on here, but I can't figure it out for the life of me. Many thanks, J.D.

With the newest version of Xcode (15.3) I cannot get Preview to load and am getting the following error: HumanReadableSwiftError CancellationError: CancellationError() I'd had this same issue a few months ago and opening up an older project's previews and then opening the project I was working on would allow Preview to show. The last few weeks I've not been getting this error and after 3 or 4 days not being in Xcode I'm getting this same error again. I'm relatively new to Xcode and Swift so not being able to load the darn preview and work through tutorials after seemingly doing the exact same thing I've been doing for months is quite ridiculous and frustrating. Any ideas on how to resolve this issue would be greatly appreciated.

When using VideoPlayer in SwiftUI it adds a black background to the video player and I would like to make it clear. Trying to add .background() of clear does nothing. Seems like a really silly "default" style to add this black background to a video. Any suggestions on how to achieve this?
