Réagir NsposixerRordomain Nadifs = 61 "Connexion refusée"

J'essaie de déployer réagir de l'application native sur mon téléphone avec un paquet hors ligne. Je n'ai pas développé pour iOS avant et je ne suis pas sûr de rechercher cette erreur. Et oui, mon application est nommée "réactnativetest", je ne savais pas que Xcode créerait un dossier nommé "ReactnativetestestStest" haha.

Alors, où dois-je commencer par ce problème? P>

    Probably at least one of the constraints in the following list is one you don't want. 
    Try this: 
        (1) look at each constraint and try to figure out which you don't expect; 
        (2) find the code that added the unwanted constraint or constraints and fix it. 
(
    "<NSLayoutConstraint:0x136f60520 V:|-(20)-[UIInputSetContainerView:0x136f5f8b0]   (Names: '|':UITextEffectsWindow:0x136f5ece0 )>",
    "<NSLayoutConstraint:0x136e2fc60 'UIInputWindowController-top' V:|-(0)-[UIInputSetContainerView:0x136f5f8b0]   (Names: '|':UITextEffectsWindow:0x136f5ece0 )>"
)

Will attempt to recover by breaking constraint 
<NSLayoutConstraint:0x136f60520 V:|-(20)-[UIInputSetContainerView:0x136f5f8b0]   (Names: '|':UITextEffectsWindow:0x136f5ece0 )>

Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger.
The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKit/UIView.h> may also be helpful.

If                 you are running on the device, check if you have the right IP                 address in `RCTWebSocketExecutor.m`.
