if you guys are trying to run admob ads, you will need a Firebase Analytics account link to admob for marketing purposes. I ran across a few issues when installing Firebase to my Xcode project using Cocoapods. Most of the problems are associated with Firebase and Cocoapods issue: #import <Firebase/Firebase.h> not found solution: Go to BBPlayer/Build settings. Go to Search Paths and add $(inherited) to both Framework Search path and Header Search paths. issue: Double-quoted include "pb.h" in framework header, expected angle-bracketed instead ( about 13 errors will pop up) solution: Go to Pods Build file (below BBPlayer) Select Pods under "Project" tab. Go to: Apple Clang - Warnings - All languages: Find "Quoted Included in Framework Header" and select No. default is Yes. This is a workaround. Issue: Undefined symbols for architecture x86_64: "_OBJC_CLASS_$_FIRApp", Solution: Go to BBPlayer, Then Target tab, Select BBPLayer, Build Settings: Go to Other Linker Flags. Add $(inherited) Afterwards run build and you should have a successful build.
