blocks:

  • SR-12229 Assertion failure when trying to pattern match enum cases with same base name

Issue Description:

Given this enum:

enum Foo {
  case base(int: Int)
  case base(string: String)
}

Pattern matching with label only works with the last enum (with the same base name).

let a = Foo.base(int: 4)

if case let .base(string: value) = a { } // Ok

if case let .base(int: value) = a { } // Error: Tuple pattern element label 'int' must be 'string'
