Could we fix the type definition instead to avoid the unsafe cast?

I think it's better for it to crash in a test, or explicitly fail, we'll get a nice stack that says it's expected to be AnyHashable but instead it's X. That preferred pattern is why hard-assert patterns like try #require are being adopted.
I could swap it to a more explicit type check assert:

let registerFriendlyObstructionArgs = try #require(instance.registerFriendlyObstructionArgs as? [AnyHashable])
#expect(registerFriendlyObstructionArgs == [friendlyObstruction])

though in practice I you'll get the same information either way it crashes.

}

func testUnregisterAllFriendlyObstructions() {
@Test func unregisterAllFriendlyObstructions() {
let registrar = TestProxyApiRegistrar()
let api = registrar.apiDelegate.pigeonApiIMAAdDisplayContainer(registrar)

let instance = TestAdDisplayContainer()
let instance = TestAdDisplayContainer(
adContainer: UIView(), viewController: UIViewController())
try? api.pigeonDelegate.unregisterAllFriendlyObstructions(
pigeonApi: api, pigeonInstance: instance)

XCTAssertTrue(instance.unregisterAllFriendlyObstructionsCalled)
#expect(instance.unregisterAllFriendlyObstructionsCalled)

private var adContainerTestValue = UIView()

I deleted this convenience method because IMAAdDisplayContainer is still an Objective-C class, and creating @MainActor classes like UIView in a non-MainActor init, I was doing acrobatics with like MainActor.assumeIsolated, but IMACompanionAdSlot is also an Objective-C class, so it wasn't @Sendable, which it needs to be when returned from MainActor.assumeIsolated, etc, etc.

There's some duplication in the tests now, but the one @unchecked Sendable is cleaner than all that.

self.init(adContainer: UIView(), viewController: UIViewController())
}

override var adContainer: UIView {
return adContainerTestValue
}

override var companionSlots: [IMACompanionAdSlot] {
return companionSlotsTestValue
}

override func register(_ friendlyObstruction: IMAFriendlyObstruction) {
registerFriendlyObstructionArgs = [friendlyObstruction]
}
