Here is the screenshot of logs so any help would be highly appreciated.

I'd like to recreate a linphone library as a framework library but i'm facing a problem with Apple Mach-O Linker.
I was trying to fix this for a week but i can't. Please help me or guide me the way to fix this.I'm new with iOS app development.(I also tried to recreate with static library and add it with subproject the problem is the same).
This is my testing xcode project.
i just download your project after run i got the smae error you were taking about "Apple Mach-O Linker". i solved the problem hope it is hepful to you.
You just need to GO >Project Target > Build Settings then search for Bitcode. You will find Enable Bitcode = "YES" Make it "NO"

while running on device and making build getting above error. Thanks in advance.
Try setting your BuildValidArchitecturesOnly in Build settings to NO.
Try adding arm7, arm64 (this is based on the type of device you are running your code) to your validArchitectures.
Try cleaning your setup.. Cmd+Shift+K
Delete Derived Data..
Use Valid developer certificate/Profile
Run & see..
It means the library not support 64 bit, you need to remove arm64 from your build settings(Project->build Settings->Architectures) if you just want to compile successfully.
If you intend to submit app to apple store, better to modify your code to make it support for 64bit.

What does this mean?
From Xcode:
dyld: Library not loaded: /System/Library/Frameworks/AVKit.framework/AVKit
Referenced from: /var/mobile/Applications/50BC86A1-5C48-444F-A41A-6AB88D43D3B0/AviaryDemo-iOS.app/AviaryDemo-iOS
Reason: image not found
It means that your code imports the AVKit headers, but the AVKit framework itself has not been linked into your target.
This problem can arise when using #import <...> syntax, and the solution would then require an extra step (namely, add AVKit manually to the linked frameworks in your target's build phases). But it cannot arise when using #import syntax, because what is imported is then a module, and you get auto-linking of modules by default. This is one of the reasons modules are Cool (technical programming term).

Wondering if I can get some direction here; I've got 18 Warnings (which I think are all deprecated functions for SDK(s) for in-ap-advertising. I'm working through them separately. The only error I have is as follows, causing me to be unable to run on both iOS Simulators and on physical devices.
clang: error: no such file or directory: '_ObjC'
The masses of text immediately above this give file paths for what looks like all the compile source paths.
I can confirm that the Build Settings - Linking-Other Linker Flags contains "-all_load" and "_ObjC".
I've had a look about and have found similar questions and tried to transpose the answers into something that will relate to my Error, but am going a bit mad right now because it's probably something really simple :|
Please let me know if you require any further information or screenshots etc., etc.
Regards,
I'm Mad
That should be -ObjC, a hyphen, not _ObjC, an underscore.
