Fix encoding Error in iOS

[WooSeongg]

Fixed an issue where URL(string:) returns nil when the query contains unencoded characters like quotes or non-ASCII text.

• iOS 17 updated URL(string:) to enforce RFC 3986 compliance automatically percent-encoding invalid characters during initialization

// example
// iOS 16
URL(string: "my string")
// ➜ nil (invalid URL due to unencoded space)

// iOS 17
URL(string: "my string")
// ➜ URL("my%20string") — automatically percent-encoded
