relates to:

SR-2241 Segmentation fault 11 using observeValue

Issue Description:

Cannot compile any iOS application due to Swift compiler crashing when compiling a Swift class that conforms to an ObjC protocol that contains NSDictionary as an argument.

Case:

import UIKit

@UIApplicationMain
final class AppDelegate: UIResponder, UIApplicationDelegate, UISplitViewControllerDelegate {

var window: UIWindow?

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [AnyHashable : Any]?) -> Bool { return true }

Compiler crashes with segmentation fault 11:

1. While generating Objective-C header
2. While printing 'AppDelegate' at <invalid loc>
3. While printing type '[AnyHashable : Any]?'
4. While printing NULL type!

Another case:

Checkout my project on Github PureSwift/GATT@1c362c9

The compiler crashes with segmentation fault 11 due to NSDictionary imported at [String: Any]

DarwinCentral.swift: LOC 344:

@objc(centralManager:didDiscoverPeripheral:advertisementData:RSSI:)
public func centralManager(_ central: CBCentralManager, didDiscover peripheral: CBPeripheral, advertisementData: [String : Any], rssi RSSI: NSNumber)

Compiler Crash:

@jckarter, you were going to look at this one, yes?

Yep, thanks Jordan.
