Added Swift code to Objective-C project.
Built and working for simulator. Failing with Undefined symbol error for Archive.
Deep investigation of compiled files
Objective-C “*.o” file wants symbol:
_OBJC_CLASS_$_AClass
But AClass.swift “AClass.o” file have only (per nm output):
0000000000002318 D _OBJC_METACLASS_$_AClass
Comparing with simulator compilation I see that AClass.swift compiled into AClass.o with:
0000000000002890 S _OBJC_CLASS_$_AClass
0000000000002398 D _OBJC_METACLASS_$_AClass
I do not understand why Archive not puts that “S OBJC_CLASS$_AClass”.
What I already did:
- cleared/removed and restarted all possible;
- having @objc attributes of cause and
- re-added swift files to Xcode (first the were placed there strange – not in group and one file showed in several places. But removed completely and re-added so compiled to simulator);
- experimented with all possible arch settings in build config;
- compared build logs in attempt to find some special flags preventing this (no special, just -DDEBUG=1 and like that). And of cause compilation and linking used different “sdk” folders. One for simulator and one for iPhone devices;
- set Debug for Archive and do not remove debug symbols. Set all ONLY_ACTIVE_ARCH to No. No effect;
- Symbols Hidden by Default is set to No.
How to build Archive finally?
