I searched long on this issue. There are several reasons causes this issue.

If you are facing when you and Swift code/library in an Objectice C project you should try Solution 1-2-3

If you are facing this issue with a new a Swift project Solution 4 will fit you best.

Solution 1:

Restart Xcode, then computer and iPhone

Solution 2:

Go to project build settings and set Embedded Content Contains Swift Code flag to YES

Solution 3:

Go to project build settings and add @executable_path/Frameworks to Runpath Search Paths option

Solution 4:

If none of above works, this should. Apple seems to be ninja patched certificates as mentioned in AirSign's post

At InHouse certificates

Subject: UID=269J2W3P2L, CN=iPhone Distribution: Company Name, O=Company Name, C=FR

they added a new field named OU

Subject: UID=269J2W3P2L, CN=iPhone Distribution: Company Name, OU=269J2W3P2L, O=Company Name, C=FR

so you should just recreate certificate and provision

Xcode->Product->Clean + Xcode Restart

After attempting many of the other mentioned solutions, to my eternal embarrassment, doing an Xcode->Product->Clean and restarting Xcode, did the trick.

I have this problem before for accidentally revoked my certificate. Then all my swift projects have this problem. There are two ways to solve this:

Click on Product → Clean (or CMD + Shift + K)

Or by manually cleaning the Xcode setting files:

rm -rf "$(getconf DARWIN_USER_CACHE_DIR)/org.llvm.clang/ModuleCache"
rm -rf ~/Library/Developer/Xcode/DerivedData
rm -rf ~/Library/Caches/com.apple.dt.Xcode
