Cannot fix "Could not find or use auto-linked library "

Question

I have an app built with Swift with pods(firebase). I have 18 triangle and 100 red errors which weren't there before. They only appear when I try to archive my app.

I have tried all of these (Adding search paths, Adding blank swift files, deleting framework paths)

It gives errors when using Swift Static library with Objective-C project

Why linker link static libraries with errors? iOS

ld: warning: Could not find or use auto-linked library 'swiftFoundation'
ld: warning: Could not find or use auto-linked library 'swiftsimd'
ld: warning: Could not find or use auto-linked library 'swiftGLKit'

Apple mentioned similar issue in known issues section:

Targets that contain Swift code with the Enable Bitcode build setting set to Yes fail to link correctly when built with the Archive action.

And give us a workaround:

Add a custom build setting with the name LD_VERIFY_BITCODE, and set it to NO. Make a note to yourself to delete this custom build setting once this issue is resolved.

For me actually, before I noticed this answer I deleted all of my pods and reinstalled them and that fixed it for me – Yuto Aug 05 '19 at 01:33

I am facing a similar issue while building my `react-native` code for iOS. This solution isn't working for me. Is there anything else that can be done? – LordAnari Apr 20 '20 at 21:03
Same issue as @LordAnari . Also getting this in react-native. Any pointers would be much appreciated. – KentAgent May 03 '20 at 21:47
@KentAgent which library are you manually linking? For me, I am trying `react-native-razorpay`. Just wondering if it has anything to do with this. – LordAnari May 10 '20 at 21:19
@LordAnari I managed to solve my issue. Please check my answer on another question here and see if that solves your problem: https://stackoverflow.com/a/61582562/8576909 – KentAgent May 11 '20 at 23:14

My ObjectiveC project was including a Swift pod which was then throwing the above errors. I found all I had to do was add a swift header file into the base of my project and it suddenly all built.

What gave it away for me was when I went into the Build Settings of my Target project and did a search for 'swift' I was only seeing a very minimal amount of results when I knew I should be seeing more - after adding the header file I suddenly saw a lot more options here. Below are the steps I took.

Right click on your root project in the Project Navigator
Select 'New File'
Select a 'Swift File'
Give it a name of 'BridgeHeader' (you don't need to specify the .swift - it'll add the extension automatically)
Run a clean + build and hopefully the errors will have disappeared!

I'm unsure if the name is important, nor am I sure on the position of the file but this is what worked for me!

Works! should be the accepted answer. Had this issue when using #import and setting setAdvertiserTrackingEnabled and it fixed my issue as I was building in Objective C — AntiPawn79, Dec 01 '21 at 21:00

Create a swift file in the main project (File.swift) and add the following code to the same

//
// File.swift
//
import Foundation

In case you see the issue after updating React Native from 0.63.x to 0.64.x, try this solution:

Create a new 0.64.x project:

npx react-native init MyApp --template react-native-template-typescript

Compare package.json of the new project and of your old 0.63.x project, and modify the old one.
Do similarly with ios/Podfile.
Run yarn install or npm install.
Run pod install in ios directory. Probably you need to remove the old Podfile.lock file.
Now, when you rebuild your project, hopefully the issue will be fixed.

In my case, it was a React-Native project after adding a Swift Pods library.

Solution 1:

Adding a new Swift file and a Bridge header:

File -> New -> File
Select Swift File
Confirm Create Bridging Header

Solution 2:

Go to Build Settings and set Always Embed Swift Standard Libraries to YES

I recently faced this issue but the offending class was a unit test class. It turned out that a pod reference in my podfile was not included in the test target.

In my case I accidentally added a test file to the main swift target. Removing it solves the problem

Here are what I did

1. go to compile source for the main target

2. search for test

3. remove it
