0.4.1

• Fixed: XCTestDynamicOverlay now builds for SwiftWASM environments (thanks @inamiy).

0.4.0

• Changed: XCTUnimplemented is now overloaded to take a non-optional placeholder, or nothing at all, to prevent ambiguity in situations where you pass a .none value.

0.3.3

• Fixed: Linux now builds correctly when statically linking against the standard library.
• Infrastructure: Cleaned up DocC.

0.3.2

• Changed: XCTUnimplemented errors now print more context, including the values passed to the function.
• Fixed: the underscored _XCTIsTesting property no longer returns false when tests run in app hosts.

0.3.1

• Changed: XCTUnimplemented will no longer fatal error when range replaceable values are to be returned. Instead, it will return an empty value.
• Changed: XCTUnimplemented overloads have been reduced, where Void-returning logic is built into the generic Result-returning functions.
• Fixed: 0.3.0 introduced a regression in which calling XCTFail outside of tests from a debug build could cause a recursive loop.
• Infrastructure: DocC documentation has been added.

0.3.0

• Added XCTUnimplemented, a function for constructing "unimplemented" closures that call XCTFail when invoked.

  Helpful for stubbing dependencies held in value types. For example, a common use of XCTest Dynamic Overlay:

  struct FactClient {
    var fetch: (Int) async throws -> String
  }
  
  extension FactClient {
    struct Unimplemented: Error {
      let endpoint: String
    }
  
    static let unimplemented = Self(
      fetch: { _ in
        XCTFail("Unimplemented: \(Self.self).fetch")
        throw Unimplemented(endpoint: "\(Self.self).fetch")
      }
    )
  }

  Can be simplified using XCTUnimplemented:

  extension FactClient {
    static let unimplemented = Self(
      fetch: XCTUnimplemented("\(Self.self).fetch")
    )
  }

• Changed: XCTFail now causes a runtime warning when called outside of tests.

0.2.1

• Changed: XCTFail functions are now no-ops in non-DEBUG builds to avoid leaking symbols into RELEASE builds.

0.2.0

• Changed: XCTFail is no longer restricted to DEBUG builds.

0.1.1

• Includes MIT LICENSE.

0.1.0

• Initial release!
