I have a react native component written in Swift, and I want to extract it as a framework so other project/people can use it easily.
First I created a new iOS project Foo, added a framework target,
then added source files. Finally, I built it.
It failed because:
Bar.swift:[lineNumber]: Use of unresolved identifier 'RCTConvert'
RNBarManager.swift:[lineNUmber]: Use of undeclared type 'RCTViewManager'
Attempt 1:
I ran react-native link, but nothing changed.
Attempt 2:
Drag React.xcodeproj to Foo project and add libReact.a to Link
Binary With Libraries.
Add $(SRCROOT)/../node_modules/react-native/React to Header Search Paths.
But it doesn't work. The error still remains.
Attempt 3:
I was thinking maybe Swift doesn't recognize these files.
So I added Foo-Bridging-Headers.h like I did in a React-Native App, which contains the following code:
#import "React/RCTBridge.h"
#import "React/RCTViewManager.h"
#import "React/RCTUIManager.h"
#import "React/UIView+React.h"
#import "React/RCTBridgeModule.h"
I also added Foo-Bridging-Headers.h to Build Settings->Swift Compiler - General->Object-C Bridging Header,
Still I got an error.
using bridging headers with framework targets is unsupported
It seems bridging headers are not allowed here.
Attempt 4:
I tried to add these imports to Foo.h,
but got an error again.
Foo.h:21:9: Include of non-modular header inside framework module 'Foo'
What should I do to compile successfully?
This seems like an issue with the cocoa pods required for linking React to your project.
Try running pod install in your project directory using terminal and then try to build.
The linking happens in the hosting app, and not in the framework you've made. That will just need the headers.

So I have an expo project, which is my main root. I have some native code nested into the project written in Swift and the Expo Module lib. All works fine until I try to import a Framework into it that sits inside the native module.
ExpoApp (with podfile)
NativeModule in swift - (with podspec)
Framework containing header files written in objectC
When I run expo run:ios I get the following error:
#import <XFramework/XDefines.h>
| ^ 'XFramework/XDefines.h' file not found
In the framework I have an umbrella header that imports all the headers with the same namespaces address. This error is coming from one of the other headers.
Is this something that I can set in the NativeModule's podspec?
Tried to add USER_HEADER_SEARCH_PATHS to the podspec in the NativeModule.
I'm new in Swift. I want to create iOS app that can connect to PostgreSQL database. First I found library https://github.com/vapor/postgresql.git that should be added to my project via Swift Package Manager. Using tutorial I added required library to my project successfully (File -> Swift Packages -> Add Package Dependency):
list of added packages from SPM
But when I try to import this module into my view controller, Xcode shows error that module is not found:
not found
I tried several times to rebuild my project, created new project just for testing this issue. Also I found information about build phases and added this lib as a dependency:
build phases
But I still get error: "No such module PostgreSQL".
Can anyone help me?
I found solution by myself. I compiled C static library "libpq" (can be found in PostgreSQL sources) and added it to my swift project. Included this library by adding special bridging header file. Finally I got what I wanted.
P.S. If someone what to repeat, he or she should know: static C library must be compiled for iOS device architecture (and also in iOS simulator architecture which differs from iOS device arch.).
I have a workspace with multiple targets and mixed development with SWIFT and Objective-C. After installing CocoaLumberjack with CocoaPods:
pod 'CocoaLumberjack/Swift'
I can use it my project without any problems. All my targets get compiled except Test target. When I run tests I get "build failed" error within the bridging header file
<CocoaLumberjack/CocoaLumberjack.h> file not found
at:
#import <CocoaLumberjack/CocoaLumberjack.h>
Do you have any ideas how to fix the issue? Thanks!
I'm trying to build a command-line tool which uses sqlite. I have downloaded Stephen Celis' swift wrapper, SQLite.swift, and built a working OS X app. However, I am not able to build my command-line tool. I believe that I correctly followed the instructions to do so in the SQLite.swift Documentation for frameworkless targets, but apparently I am missing something. I get an error in Helper.swift # import CSQLite -> No such module 'CSQLite'.
I am linking against libsqlite3.dylib (also tried libsqlite3.tbd)
I added the SQLite.swift source to my project
I added #import sqlite3.h & #import "SQLite-Bridging.h" to my bridging header file. Perhaps of note, when I right-click on sqlite3.h or SQLite-Bridging.h, xCode does not know where/what they are.
I'm happy to send my test project (about 80KB, compressed) to anyone who can and is willing to help. There is probably a very simple solution, I just do not see what it is.
thx for any help,

I've faced the same problem.
There were lots of compiler errors like "Connection.swift:26:8: Could not build Objective-C module 'CSQLite'"
The error has roots to the "lctx.h:13:25: Use of undeclared identifier 'SYS_getlcid'"
It worth mentioning that I have two Xcodes installed - v 6.2 at /Applications and v 7.3 at ~/Applications. My project is iOS app on Swift with SQLite pod and I open it with the Xcode 7.3.
The SQLite pod has a file at project_folder/Pods/SQLite.swift/CocoaPods/iphonesimulator/module.modulemap.
The file had the content
module CSQLite [system] {
header "/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/usr/include/sqlite3.h"
export *
}
To fix compiler errors I changed the content of module.modulemap to
module CSQLite [system] {
header "/Users/my_user_name/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/usr/include/sqlite3.h"
export *
}
The change is that I pointed search of sqlite3.h into my ~/Applications folder where Xcode 7.3 is located.
This made my project compiling.
I'm trying to get Earlgrey setup on my computer by following the steps for Cocoapod installation as described here
After performing all the steps I keep on getting compilation error during build
EarlGrey.swift:17:27: Use of undeclared type 'EarlGreyImpl'
There are 13 such compilation errors all related to unresolved identifier.
I re-tried the steps multiple times with same results. My folder structure matches with what is shown in the instructions.
Any suggestions where should i look further to get this resolved.
For reference i'm using this swift project as base for writing test cases.
So the issue was related to BridgingHeader.h file setting in
test target -> build Setting -> Swift compiler -Code generation -> Objective-C bridging Header
I copied the file from demo project, but did not specify it in the above setting. Once specified there, the compilation errors was gone.
Try importing EarlGrey using #import <EarlGrey/EarlGrey.h> instead of #import EarlGrey;
