I'll describe my crash with an example, looking for some insights into the reason why this is happening.
@objc public protocol LauncherContainer {
var launcher: Launcher { get }
}
@objc public protocol Launcher: UIViewControllerTransitioningDelegate {
func initiateLaunch(url: URL, launchingHotInstance: Bool)
}
@objc final class LauncherContainer: NSObject, LauncherContainer, TabsContentCellTapHandler {
...
init(
...
) {
...
super.init()
}
...
//
// ContentCellTapHandler
//
public func tabContentCellItemDidTap(
tabId: String
) {
...
launcher.initiateNewTabNavigation(
tabId: tabId // Crash happens here
)
}
public class Launcher: NSObject, Launcher, FooterPillTapHandler {
public func initiateNewTabNavigation(tabId: String) {
...
}
}
public protocol TabsContentCellTapHandler: NSObject {
func tabContentCellItemDidTap(
tabId: String,
}

Crash stack last 2 lines are- libswiftCore.dylib swift_unknownObjectRetain libswiftCore.dylib String._bridgeToObjectiveCImpl()
String._bridgeToObjectiveCImpl() gets called when the caller and implementation is in Swift file
I believe due to @objc class LauncherContainer there'd be bridging header generated. Does that mean tabId passed to tabContentCellItemDidTap is a String but the one passed to initiateNewTabNavigation is NSString?
TabId is UUID().uuidString if that helps. Wondering if UUID().uuidString has something to do with this.
Thanks a ton for helping. Please find attached screenshot of the stack trace.
