I'm using ADAL via cocoapods in my iOS project.
Xcode: 9.2
ADAL: 2.5.4
When building I get this warning:
instance method 'speInfo' in category from /Users/user/Library/Developer/Xcode/DerivedData/Mobile-echesuhdqeeauvgypmfgbpnmnsjl/Build/Intermediates.noindex/Pods.build/Debug-iphonesimulator/ADAL.build/Objects-normal/x86_64/ADTokenCacheItem+Internal.o overrides method from class in /Users/user/Library/Developer/Xcode/DerivedData/Mobile-echesuhdqeeauvgypmfgbpnmnsjl/Build/Intermediates.noindex/Pods.build/Debug-iphonesimulator/ADAL.build/Objects-normal/x86_64/ADTokenCacheItem.o
I tried cleaning the derived data folder and doing a clean in Xcode, it didn't help. I also updated ADAL from 2.5.2 to 2.5.4 (pod install), it didn't help as well.
I added -Xlinker -no_objc_category_merging
to the Other Linker Flags
and the warning was suppressed.
