INVoiceShortcutCenter.shared.setShortcutSuggestions(suggestions) 在 iOS 13 Beta 中崩溃。 Xcode 11 测试版

Question

My code is pretty straight forward. I am not sure what is the issue and I am not able to find a solution.

var suggestions = [INShortcut]()

for component in components
{
    if let userActivity = UserActivityGenerator.getUserActivity(component: component)
    {
        let shortCut = INShortcut.init(userActivity: userActivity)
        suggestions.append(shortCut)
    }
}

INVoiceShortcutCenter.shared.setShortcutSuggestions(suggestions)

The app crashes in setShortcutSuggestions .

It works fine in iOS 12 with same Xcode 11 Beta.

Answer 1

Execute the function in the main queue.

   DispatchQueue.main.async {
        INVoiceShortcutCenter.shared.setShortcutSuggestions(suggestions)
    }
