I can solve it this way but I'm worried there will be some problems

[dongxianbin]

Build Settings -> Runpath Search Paths: @executable_path/Frameworks

[vahancouver]

Build Settings -> Runpath Search Paths: @executable_path/Frameworks

@dongxianbin Can you please explain? I have my Runpath Search Paths: @executable_path/Frameworks and still getting the same error

[dongxianbin]

Build Settings -> Runpath Search Paths: @executable_path/Frameworks

@dongxianbin Can you please explain? I have my Runpath Search Paths: @executable_path/Frameworks and still getting the same error

I compared my project with another functioning one and realized that my project was lacking an essential element - Build Settings -> Runpath Search Paths: @executable_path/Frameworks. Upon making this necessary modification, my project started running smoothly.

Same for me!

Also worth mentioning that this issue happens while running on a device only (works fine on a simulator)

PS. I'm using SPM

[dongxianbin]

I don't have any other way. I created a new app using Xcode, imported FBSDKv17.0.0, and then ran it normally. Then, I compared the new Xcode project with my own Xcode project and found a solution. You can also try it out.

[zhoubo6419]

I'm using pod same problem

[FabianBartels]

The same happened to me:

It works fine for the simulator but crashes for the real device.

Not sure but as i checked my folder structure i detected that the folder .../PackageFrameworks/.. in path /Users/XXX/Library/Developer/Xcode/DerivedData/XXX-hevagtfawervsfccdbpjpkfiqeqp/Build/Products/Debug-iphoneos/PackageFrameworks/FBSDKCoreKit.framework does not even exists so it cant find FBSDKCoreKit.framework there.

However, when navigating to the directory to the parent dir of PackageFrameworks (/Users/XXX/Library/Developer/Xcode/DerivedData/XXX-hevagtfawervsfccdbpjpkfiqeqp/Build/Products/Debug-iphoneos/FBSDKCoreKit.framework) i can find the FBSDKCoreKit.framework.

So far i think i need to find a way to change the dir somehow :).

Letting you know if this is not an dead end.

[vahancouver]

In my case I'm adding the FB SDK via SPM in a framework as a dependency, than using that framework in a an app.
That's when i'm getting this error.

But when I create a brand new app and directly add FB SDK via SPM, I see no issues.

This means something is different when the FB SDK is added to a framework target.
@dongxianbin is this helpful at all? any chance you can test this on your side?

Thanks.

PS. This is a new issue in 17.0.0. It works with no issues on 16.1.0

[dongxianbin]

@vahancouver ，My original Xcode project was created through Cocos, so there may be some differences in Build Setting compared to normal Xcode projects. I compared the methods you mentioned and found a solution. This issue did not occur before version 17.0.0. Different Xcode projects may have different problems, so it is recommended that if the same problem occurs, you create a new app using Xcode, import FBSDK according to your own method, and then compare the differences between the two projects before, step by step, to modify and test. There is no other good way.

[VikasTTN]

I'm also encountering the same problem. After updating SPM to version 17.0.0, the app crashes during launch on iOS 13.

[aleufms]

I'm having the same issue. It's because we do not import the facebook lib directly in our project, but through an module: our app -> libs module (have all the libs through spm) -> facebook sdk.

[VikasTTN]

@aleufms any solution for this ?

[aleufms]

@VikasTTN no :(

[aleufms]

@VikasTTN I have workarounded this issue. I have imported the lib in the app too, and it is working on actual devices. Not ideal, but it an temporary solution.

[george-bafaloukas-forgerock]

Same issue exists on version 18.0.0 when integrating as part of a module using SPM.

Any solutions @aleufms @dongxianbin
