Why do i get 'ambiguous reference to member' in swift?

This error arises when the Swift compiler can't decide between multiple possible meanings or uses of a particular member, often due to type ambiguity.

Example:

  let numbers = [1, 2, 3]
  print(numbers.map)
  
Solution:

  let doubled = numbers.map { $0 * 2 }
  print(doubled)
