In the search for swift strings, it is sometimes possible to return a range rather than a specific location. This will use the concept of range in Swift. We'll take a detailed explanation of this.

Dataannotations provides requiredattriations for null, empty, and stringlengthattribute for String Length verification. It is strange that a stringlengthrangeattribute verification is not provided. For example, when verifying input, the password may be in the range of 6-20.
