Initializer for conditional binding must have Optional type not String

The error message suggests that the initializer for a conditional binding statement must have an optional type, not a string type.

Conditional binding is used to safely unwrap optional values and execute code only if the optional value is not nil.

For example, consider the following code:

let optionalString: String? = "Hello, world"

if let unwrappedString = optionalString {
    print(unwrappedString)
} else {
    print("Optional string is nil")
}

In this code, optionalString is an optional string. The conditional binding statement if let unwrappedString = optionalString checks if optionalString is not nil. If it is not nil, the value is unwrapped into unwrappedString, and the code inside the if block is executed. Otherwise, the code inside the else block is executed.

If you are encountering the error message "Initializer for conditional binding must have Optional type, not 'String'", it means that you are trying to use conditional binding on a non-optional value. In this case, you should remove the conditional binding statement and handle the non-optional value accordingly
