You are building an app, not a framework right? Do you reference any external framework? Have you tried to force clean and build again? Are you building with the right target? — Antonio Romano, Feb 14 '16 at 14:35

I found this issue some months back. It was cause by Apple's default certificate being expired.

This resolved my issue.

Go to keychain access
Select "System" in "Kechains" and "All Items" in "Category"
There will be a certificate with name "Apple Worldwide Developer Relations Certification Authority". Check if it's valid
In my case, it had been expired. Delete that certificate if it's expired or is showing as signed by unauthorized identifier
Goto https://www.apple.com/certificateauthority/ and download "Worldwide Developer Relations - G2 Certificate" under "Apple Intermediate Certificates"
Install the certicate
Clean, Build and run.

Worked for me, even though my certificate was "valid". I've installed the mentioned one and the problem's gone! Thanks a lot, @varun — EBDOKUM, Oct 26 '16 at 13:56

In Xcode, you can go to Window -> Projects, and find your project name and delete "Derived Data". This should resolve your issue.

My solution is as below:

go to "TARGET" > "Build Settings";
search for "Runpath Search Paths", check if value contains "$(inherited)" & "@executable_path/Frameworks", add them if doesn't;
clean and rebuild project.

That's all.

I deleted the "Derivered Data" and that fixed the issue.

For people who have xcode 8.3 the path is :

in "File" or in "Workspace Settings" --> "Project Settings" --> click the gray arrow under the "Derived Data" --> Select your project folder and delete it.

Hope this helps!

For me Following steps helped me:

1.Delete your app from device

2.From "TARGET">"Build Settings">"Runpath Search Paths" ^ then check for values "$(inherited)" & "@executable_path/Frameworks", Feel free to add incase they dont exist

Build your app and run it on device

Now (2017 June) at Xcode 8.3.2, Swift 3 and iOs 10.3, my solution - after trying many possible solution who did't work for me - for this issue was at Keychain Access. I have deleted Apple Worldwide Developer Relations Certificate Authority and then I have downloaded and installed a new one. After that, I have changed "trust"(double-click the certificate) from "always" to "system default". Now everything is fine.

Ok. i solve this a little bit different way. As you know, grater than Xcode 7, you can run your iOS project(only one iphone) on your iphone without purchase Apple Developer Program(registration is enough).

if you have a Apple ID and not purchased yet.
And you was build on the different iPhone(Divece A)
Now, you want to build different iPhone(Divece B)

for this scenario, you can get an error which is detailed below

dyld: Library not loaded: @rpath/libswiftCore.dylib uzun hali de dyld: Library not loaded: @rpath/libswiftCore.dylib Referenced from: /private/var/mobile/Containers/Bundle/Application/LONGSERIALNUMBER/AppName.app/AppName Reason: no suitable image found.

You must delete Provision Profile or you should get new Apple Developer account for new iPhone.

I had this problem with Facebook SDK in unity build for xcode on iOS version 12 and below. The problem is Facebook SDK in version 7.21.2 but it is not in earlier versions. I used 7.21.1 and dont have problem.
