Description:
I created CollectionView in two ways, but both panicked

Relevant Code

Using CollectionViewDiffableDataSource

main.go

package main

import (
    "runtime"

    "github.com/charliego3/assistant/utility"
    "github.com/progrium/macdriver/macos/appkit"
    "github.com/progrium/macdriver/macos/foundation"
    "github.com/progrium/macdriver/objc"
)

const collectionIdentifier = appkit.UserInterfaceItemIdentifier("collectionItemIdentifier")

func main() {
    runtime.LockOSThread()
    defer runtime.UnlockOSThread()
    app := appkit.Application_SharedApplication()
    delegate := new(appkit.ApplicationDelegate)
    delegate.SetApplicationDidFinishLaunching(launched)
    delegate.SetApplicationShouldTerminateAfterLastWindowClosed(func(appkit.Application) bool {
	    return true
    })
    app.SetDelegate(delegate)
    app.SetActivationPolicy(appkit.ApplicationActivationPolicyRegular)
    app.ActivateIgnoringOtherApps(true)
    app.Run()
}

func launched(foundation.Notification) {
    w := appkit.NewWindowWithSizeAndStyle(
	    700, 500,
	    appkit.WindowStyleMaskTitled|
		    appkit.WindowStyleMaskClosable|
		    appkit.WindowStyleMaskMiniaturizable|
		    appkit.WindowStyleMaskResizable,
    )
    objc.Retain(&w)

    collection := appkit.NewCollectionViewWithFrame(utility.RectOf(utility.SizeOf(500, 500)))
    flowLayout := appkit.NewCollectionViewFlowLayout()
    flowLayout.SetItemSize(utility.SizeOf(100, 100))
    flowLayout.SetMinimumInteritemSpacing(20)
    flowLayout.SetMinimumLineSpacing(10)
    collection.SetCollectionViewLayout(flowLayout)
    collection.RegisterClassForItemWithIdentifier(appkit.CollectionViewItemClass, collectionIdentifier)

    datasource := appkit.NewCollectionViewDiffableDataSourceWithCollectionViewItemProvider(
	    collection,
	    func(collection appkit.CollectionView, indexPath foundation.IndexPath, identifier objc.Object) appkit.CollectionViewItem {
		    item := collection.MakeItemWithIdentifierForIndexPath(
			    collectionIdentifier, indexPath,
		    )
		    id := foundation.StringFrom(identifier.Ptr())
		    if item.TextField().IsNil() {
			    item.SetTextField(appkit.TextField_LabelWithString(id.String() + "--"))
		    } else {
			    item.TextField().SetStringValue(id.String() + "++")
		    }
		    return item
	    },
    )
    snapshot := appkit.NewDiffableDataSourceSnapshot()
    snapshot.AppendSectionsWithIdentifiers([]objc.IObject{
	    foundation.String_StringWithString(string(collectionIdentifier)),
    })
    snapshot.AppendItemsWithIdentifiers([]objc.IObject{
	    foundation.String_StringWithString(string(collectionIdentifier)),
    })
    objc.Call[appkit.CollectionViewDiffableDataSource](datasource, objc.Sel("applySnapshot:animatingDifferences:"), snapshot, false)

    w.SetTitle("CollectionView Demo")
    w.Center()
    w.SetTitlebarAppearsTransparent(false)
    w.SetContentView(collection)
    w.SetContentSize(utility.SizeOf(800, 600))
    w.MakeKeyAndOrderFront(nil)
}
