Thanks, I downloaded your app and compared it to mine, and I can’t see any obvious differences that would affect my app. I tried running yours and got the error:
ld: file not found: /Users/xxx/Downloads/Single-Object-Prelink-Framework-Demo-master/../../../../Library/Developer/Xcode/DerivedData/SIngleObjectPrelink_Demo-bllgcoioetqcmcfvgnmxwdkseync/Build/Products/Debug/libMyLibrary.a I changed your prelink libraries path to $(CONFIGURATION_BUILD_DIR)/libMyLibrary.a which resolved the problem with your app. I then added the same path to my own project in the hope that it may solve mine too, but still the same error :( Noticed a couple of differences in the build settings, changed “perform single object peeling” & “precompile prefix header" to YES Then added -ObjC to "Other linker flags” (which I had previous added then taken out because it made no difference to the ‘bug’) and….. bingo!! It works!
