How to get field names and field types from a Generic Type in Scala?

In Scala, given a generic type T, how to retrieve the list of field names and the field types? For example, if I have the case class:

case class Person(name: String, age: Int, gender: Boolean)

And the generic function:

def getFieldNamesAndTypes[T](): Seq[(String, String)]

I would like to be able to retrieve a sequence (in order that the fields appear) of the fields (name, type):

val fieldNamesAndTypes = getFieldNamesAndTypes[Person]()

It seems that you need the reflection API:

Welcome to Scala 2.13.1 (OpenJDK 64-Bit Server VM, Java 1.8.0_222).
Type in expressions for evaluation. Or try :help.

scala> import scala.reflect.runtime.universe._
import scala.reflect.runtime.universe._

scala> def getFields[T: TypeTag] = typeOf[T].members.collect {
     |   case m: MethodSymbol if m.isCaseAccessor => (m.name.toString, m.returnType.toString)
     | }
getFields: [T](implicit evidence$1: reflect.runtime.universe.TypeTag[T])Iterable[(String, String)]

scala> case class Person(name: String, age: Int, gender: Boolean)
defined class Person

scala> getFields[Person]
res0: Iterable[(String, String)] = List((gender,Boolean), (age,Int), (name,String))

You can do this even at compile time using Shapeless (i.e. using compile-time reflection under the hood)

import shapeless.labelled.FieldType
import shapeless.ops.hlist.{FillWith, Mapper, ToList}
import shapeless.{HList, LabelledGeneric, Poly0, Poly1, Typeable, Witness}
object fieldTypePoly extends Poly1 {
implicit def cse[K <: Symbol, V](implicit
witness: Witness.Aux[K],
typeable: Typeable[V]
): Case.Aux[FieldType[K, V], (String, String)] =
at(_ => witness.value.name -> typeable.describe)
}
object nullPoly extends Poly0 {
implicit def cse[A]: Case0[A] = at(null.asInstanceOf[A])
}
def getFieldNamesAndTypes[T] = new PartiallyApplied[T]
class PartiallyApplied[T] {
def apply[L <: HList, L1 <: HList]()(implicit
generic: LabelledGeneric.Aux[T, L],
mapper: Mapper.Aux[fieldTypePoly.type, L, L1],
fillWith: FillWith[nullPoly.type, L],
toList: ToList[L1, (String, String)]
): Seq[(String, String)] = toList(mapper(fillWith()))
}
case class Person(name: String, age: Int, gender: Boolean)
getFieldNamesAndTypes[Person]() // List((name,String), (age,Int), (gender,Boolean))
