Failed to build ContentView.swift

Usually, a build error indicates that you have syntax errors in your code, missing things, typos, whatever. So what you can do is to fix those errors and try again.

Would be lots easier to help if you show 1) the error message 2) you code. If you can show the code, may be against your company (if any) policy to show code on public discussion forums.

Iff you cannot find where the error is, you could:

• comment out most of the body, keeping just a Text("Hello")
• send progressively uncomment parts until you fail to build
• the error is in the last uncommented part
