在“FIRDynamicLink*”型別的物件上找不到屬性“utmParametersDictionary”-有解無憂

語意問題（Xcode）：在“FIRDynamicLink *”型別的物件上找不到屬性“utmParametersDictionary”/Users/jeremydormevil/.pub-cache/hosted/pub.dartlang.org/firebase_dynamic_links-4.1.1/ios/Classes/FLTFirebaseDynamicLinksPlugin。 m:26:47 當我查看代碼時，問題似乎來自這一行：

dictionary[@"utmParameters"] = dynamicLink.utmParametersDictionary;

uj5u.com熱心網友回復：

運行pod update以獲取至少 Firebase 7.7.0，這是在utmParametersDictionaryAPI 中引入的。
