Question

When I compile my code on XCode Version 10.0 I get this single error bringing the compilation to failure:

I will try all the possibility but can't solve the error

• Clean My project alt + Shift + Command + K
• deleting ~/Library/Developer/Xcode/DerivedData
• Pod Update

Answer 1

If you look above the error, XCode will tell you which class is added/declared twice, navigate to it and remove the reference. Build and you're good to go.

Answer 2

A suggestion is to update the pods to the latest. I recently stucked into a similar type of problem. so I did this and it worked for me. my pod version was older.

check it with pod --version, may be this helps you.

pod deintegrate
pod install
pod update
