Linker error after upgrading Xcode 7.3 to 8.3.1

Question

I am facing linker error after upgrading Xcode from 7.3 to 8.3.1, below is the error coming at the time of project build:

    Undefined symbols for architecture x86_64:
  "_OBJC_CLASS_$__TtCC13Test11AppDelegate12loggedinUser", referenced from:
      objc-class-ref in UIView+Toast.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Architecture Settings in Build Setting:

Compile Sources: Please help. Thanks in advance.

@SargisGevorgyan I checked this but it does not solved my problem. It works fine in Xcode 7.3. Problem comes after I upgraded the Xcode. — Vaibhav Agarwal, Apr 14 '17 at 12:41

Check your TestAppDelegate class, especially property loggedinUser. There should be some clues.

This may be a problem, that the target you are compiling is using the UIView+Toast file, which requires the TestAppDelegate to also be compiled. Check your project settings -> build phases -> compile sources and check if any entries are colored red (missing under the path) or are just not there, and readd them.

Hello @Alistra, thanks for replying. Every thing fine in project settings -> build phases -> compile sources. – Vaibhav Agarwal Apr 14 '17 at 12:38
Do you mean that you have both `UIView+Toast` and `TestAppDelegate` there present? – Alistra Apr 14 '17 at 12:41
No this file is not there in compile source. – Vaibhav Agarwal Apr 14 '17 at 12:46
I added TestAppDelegate and still not working. I am stuck here. Pleae help – Vaibhav Agarwal Apr 17 '17 at 05:09
