Expected ‘{ after ‘if’ conditions

Var childObject: String

} else {
ChildObject = path

return storagePath(with: bucket, object: child: childObject)

Hello @Tsi

You have posted your question in the wrong place. Compiler is for compiler related discussions. Please post it in Using Swift section.

Also, your code is full of syntax errors. It is also hard to read because it is not properly formatted. You can format it by surrounding your code with a pair of three back-tick characters ( ```) like this:
```
Paste code here
