I added use_frameworks! in my pod file, running pod install again (without any other changes). Then I got the compiler error like 'Masonry.h' file not found with <angled> include; use "quotes" instead.
Although I believed those pod header files should be used with <...> I did change them to "...". But then I got the error like Redefinition of 'FMTokenizerCursor' (from FMDB pod)
I felt like this maybe a cocoapod bug (I am using 1.0.1) so I upgraded it to cocoapods-1.1.0.beta.2, same error. pod deintegrate & pod install made no difference.
I found these is a similar question here. But the answers there did not work for me.
I tried both Xcode 7 & 8, clean ~/Library/Developer/Xcode/DerivedData
same error too.
