Hsearch call chooser:hide() block me 3 seconds

[Sean10]

When i open the hammerspoon console, hide()/show() has no blocked time. When i switch to other program, i press option+g show the chooser which has no blocked time.When i need to press option+g again to hide it , there is always 3 seconds which i have to wait. I add print to find which function cause the block, i found the obj.chooser:hide() cause the stuck. But i don't know how to debug objective-c, is there anyone has the same situation like me ?

environment: 10.12.6
spoon: HSearch.spoon
line: 224-254.

@latenitefilms I have updated the code and log, could you give me any suggestion?

function obj:toggleShow()
    if #obj.sources_overview == 0 then
        -- If it's the first time HSearch shows itself, then load all sources from files
        obj:loadSources()
        -- Show sources overview, so users know what to do next.
        obj.chooser:choices(obj.sources_overview)
    end
    if obj.chooser:isVisible() then
        print(1)
        -- hs.timer.doAfter(0, function() obj.chooser:hide() end)
        obj.chooser:hide()
        print(2)
        obj.trigger:disable()
        print(3)
        for _,val in pairs(obj.hotkeys) do
            for i=1,#val do
                print(5)
                val[i]:disable()
            end
        end
    else
        if obj.trigger == nil then
            obj.trigger = hs.hotkey.bind("", "tab", nil, function() obj:switchSource() end)
        else
            obj.trigger:enable()
        end
        for key,val in pairs(obj.hotkeys) do
            if key == obj.source_kw then
                for i=1,#val do
                    val[i]:enable()
                end
            end
        end
        obj.chooser:show()
    end
end

Can you share your code?

You could try wrapping the chooser:hide() in a hs.timer.doAfter(0, function() chooser:hide() end)?
