类型“ SomeVC”不符合协议“ NextLevelDelegate”（与Swift 4.1.2编译）

Question

Type 'InPersonVideoRecordingVC' cannot conform to protocol ' NextLevelDelegate ' (compiled with Swift 4.1.2 ) because it has requirements that could not be loaded in Swift 3.3.2

I am using NextLevel Video Recording Library using Cocoapods

This started after i updated to Xcode 10

Answer 1

请确保桥接头中包含NextLevelDelegate中引用的类。

Answer 2

You are using NextLevel Video Recording Library which is compiled with Swift 4.1.2 and it might have some swift version based independencies which is unavailable in your project with swift version 3.3.2 .

What to do?

Try finding the swift 3.3.2 compiled version of NextLevel Video Recording Library, or use another library.
