Xcode showing error with embedded framework but it compiles well

Question

I have an app with a custom Swift framework that is used to share business rules across different plateform. Every time I try to use a class from this framework, Xcode is showing me errors but everything compiles well. It also preventing me from using autocompletion regarding this framework.

I already try cleaning and deleting derived data but without any results.

My framework is included in my main projet via a submodule and manually linked on my main project.

Any thoughts on this ?

If it compiles and works ok, try cleaning your project (shortcut CMD + Shift + K) and then build it once again — mcgtrt, May 30 '18 at 08:53
@mcgtrt I already try several times, along with deleting derived data — Yaman, May 30 '18 at 08:54
@Anbu.karthik Just checked, every file is part of the framework target — Yaman, May 30 '18 at 08:56

I had a similar problem in Obj-C project and setting `Precompile Prefix Header` to `No` in the build settings was helpful to me. Dunno if it would work for Swift. — mcgtrt, May 30 '18 at 08:58
@Anbu.karthik just checked the link, nothing relevant for me unfortunatly — Yaman, May 30 '18 at 09:04
try to set the same iOS deployment target values for the main app target & Pods targets. — Mohamed Raffi, May 30 '18 at 09:11
@MohamedRaffi It is the same deployment target already. I forgot to specify that that framework is not embedded via Cocoapods but via a submodule — Yaman, May 30 '18 at 09:13
Check your Compile Sources in Build Phases. May be same classes added twice. — Mohamed Raffi, May 30 '18 at 09:18
@MohamedRaffi Not for the example I put on my post. However I do have other class that has same name but I'm always prefixing thoses classes with the framework name, i.e `BusinessRulesKit.Job`. And I just checked, everything is good in Compile Sources — Yaman, May 30 '18 at 09:18
Don't think this is a solution, but just in case, did you declare your class 'BusinessRules' as public? — juancazalla, Jun 06 '18 at 17:33

My custom Swift framework class:

public class Myfile {
    public func textmethod(){
        print("The value of textmethod")
    }
}

Imported framework to the project

My ViewController file:

import MyFrameWork

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        let log = Myfile()
        log.textmethod()
    }

}

I think your problem is with the framework's search path. I assume its now set for the target but not for the project (or incorrectly set on the project). You can set it only for the project and let Xcode handle target path.

Xcode has a separate compilation process for computing autocomplete references, from the compilation process for actually building your project. If you accidentally set the framework search path for your target instead of the project as a whole, your project will seem to build fine. https://medium.com/@_achou/one-weird-trick-to-fix-autocomplete-in-xcode-9f19dc856944

Solution 1: Fix framework search path in Project - Build Settings.

Solution 2: Remove the framework from your project, head to Targets - Build Phase - Embeded Frameworks, click on + (add) and then Add Other and find it in your directory.

Try removing your framework then CMD+B close XCODE open it again add the framework again and CMD+B. By the way have you moved your project folder recently??

I have noticed the same problem recently. The solution I found that I had to run the app in the simulator for then the xCode to start recognizing the framework and hence to get the autocomplete feature..

Give it a try..!

Are you using git in this project? As odd as it may sound, I've resolved similar issues by committing the current code.

I did face the same problem recently. I solved it by setting the framework and header search path to non-recursive in the project scope and pointing directly to the correct directory without subfolders. My target then inherits the search paths from the project.
