Mach-O Linker error Xcode
I just completed an iOS project in Unity and am trying to build and run it in Xcode. Admittedly, I'm pretty clueless when it comes to Xcode, but my app won't run because I have about a hundred Mach-O linker errors on the side. I'm using 4.6.3. Any advice how to get this fixed?
Update: So I tried to delete my derived data which seemed to fix it and I was successfully able to run my app but it stopped because I didn't have the Unity splash screen. Would deleting my derived data do this? I can't think of anything else that would delete the splash screen. The problem is the derived data isn't arm64, but I'm using Unity 4.6.3 so shouldn't it be arm64? I'm not using any plugins. I'm really confused.
Hi,
I have had the same problem. But the one thing you must not do, is verify your project in Xcode, just compile as is. I think the linker errors will go away then,
hmmm not, if there is an error, it just does not disappear because you think it will.
I was also getting this bug when i used facebook third party plugin I solved it by commenting those error lines in xcode
if you are using Iads or social media try to import it in xcode
hope it will help
The first errors are related to Metal, and that API will only build on devices it was made for (just the very latest ios devices). The other error I can't really say anything about. Did you remove any files manually?
No I didn't remove any files manually. Here are a few more of the errors I got. Sorry it's so messy.

Have you added the frameworks and libraries
which social plugins you are implemented in you project ? (are you implements Applovin,Facebook ?) This error is confling with unity 4.6+.
None. I'm not using iAd, and I don't know what have of the stuff is so it all seems bizarre to me. I didn't install any plugins. I am using 4.6.3. Xcode is Greek to me.
Interestingly, after the app crashes, the powered by Unity splash screen comes up through the multitasking view.
@sudhir_kotila I am also getting same error. I am using applovin, chartboost and revmob plugins.
I had the same problem. I made a video to show you how to fix it. https://www.youtube.com/watch?v=j3UzJSRex_E
