[BUG] Unable to attach Validator on iris Application

[dpkahuja-jg]

Describe the bug A clear and concise description of what the bug is. Unable to attach validator on iris Application instance.

app.Validator undefined (type *iris.Application has no field or method Validator)

To Reproduce Steps to reproduce the behavior: example here https://github.com/kataras/iris/blob/master/_examples/request-body/read-json-struct-validation/main.go

Expected behavior A clear and concise description of what you expected to happen. Validator should attach Screenshots

Desktop (please complete the following information):

• OS: [e.g. ubuntu, windows]

iris.Version

• e.g. v12.2.0-alpha or master

Please make sure the bug is reproducible over the master branch:

$ cd PROJECT
$ go get -u github.com/kataras/iris/v12@master
$ go run .

Additional context Add any other context about the problem here. Even if i use readJSON to read the body with struct tags described in example, no error is thrown. validator is expected to run manually. Am i missing anything?

v12.2.0-alpha iris.go line:339

err := app.Validator.Struct(v)
if err != nil {
	if !strings.HasPrefix(err.Error(), "validator: ") {
		return err
	}
}

while validate failed, but !strings.HasPrefix(err.Error(), "validator: ") omit。
