Swift GRDB 4140 Trailing closure passed to parameter of type String that does not accept a closure

The error message "Trailing closure passed to parameter of type 'String' that does not accept a closure" occurs when you try to pass a closure as an argument to a function that doesn't expect one.

In the case of Swift's GRDB library, the error can occur if you mistakenly pass a closure as an argument to a method or function that expects a different type, such as a String.

To fix this error, you need to make sure that you are passing the correct type of argument to the function. Double-check the documentation or function signature to verify the expected argument type.

Here's an example of how this error can occur and how to fix it:

import GRDB

// Define a function that expects a String argument
func processString(_ string: String) {
    print(string)
}

// Call the function with a trailing closure
processString { // Error: Trailing closure passed to parameter of type 'String' that does not accept a closure
    print("Hello")
}

// Fix: Pass a String argument instead of a closure
processString("Hello")

In the code above, the processString function expects a String argument. However, we mistakenly passed a closure instead, resulting in the error. To fix it, we need to pass a String argument instead, like "Hello"
