问题
I followed all kinds of tutorials and tried different things, but no help. I successfully installed cocoaPods via Terminal and initialised a pod file. After figuring out how to solve "import Firebase error", now I have difficulties with simple operations like trying to write data into database. Xcode error when trying to write data
My pod file
回答1:
The new Firebase SDK 3.2.0 has several breaking changes compared to the old version 2.x, therefore the old Quick Start guide is completely obsolete. All classes have been renamed, and the integration process is different. So use new pod file. It will help you. You can also do it by adding them directly which is also mentioned on there original web site.
You must follow the new guide on firebase.google.com instead.
