该接口位于System.Diagnostics.SymbolStore.ISymbolScope中，它具有我要使用的方法。但是我似乎无法将其实例化为一个对象。我似乎没有可供选择的班级选择。如何创建此实例？谢谢。

您不能直接实例化任何接口。对于ISymbolScope，您需要执行与下面的代码所示类似的操作，在该代码中，您还需要引用“使用Microsoft.Samples.Debugging.CorSymbolStore.SymbolAccess;”
func loadCards() {
// shortcuts
if valueArray.count > 0 {
let capCount = (valueArray.count > MAX_BUFFER_SIZE) ? MAX_BUFFER_SIZE : valueArray.count
for (i,value) in valueArray.enumerated() {
let newCard = createTinderCard(at: i,value : value as! NSDictionary )
allCardsArray.append(newCard)
if i < capCount {
currentLoadedCardsArray.append(newCard)
}
}
for (i,_) in currentLoadedCardsArray.enumerated() {
if i > 0 {
viewTinderBackGround.insertSubview(currentLoadedCardsArray[i], belowSubview: currentLoadedCardsArray[i - 1])
}else {
viewTinderBackGround.addSubview(currentLoadedCardsArray[i])
}
