Hello, I know one cause of this error and I am assuming it is a bug in xcode. If you have comments on the same line as an opening bracket of a closure or an if statement or anything of that nature it will throw this error. As far as I know comments should have no effect on your code which is why I am pretty sure this is a bug but if you still have this issue check the lines with opening brackets for comments and delete them that should fix it! Hope this helps Current XCode Version: 11.4.1
