Push Segue Not Found Error When Testing on Device but Works on Simulators

The push segue is a fundamental concept in iOS development that allows you to programmatically navigate between view controllers. However, when testing on a physical device, the push segue may not work as expected, resulting in an error message indicating that the receiver has no segue with the specified identifier.

In this article, we’ll delve into the world of segues and explore possible reasons behind this issue. We’ll examine the stacktrace, discuss potential causes, and provide a step-by-step solution to resolve the problem.

Understanding Segues

Before diving into the error message, let’s briefly review what a segue is. A segue is a connection between two view controllers in the storyboard that allows you to programmatically navigate from one controller to another. When you create a segue, you’re essentially telling Xcode to establish a link between the current view controller and another view controller.

In the provided stacktrace, we see an NSInvalidArgumentException exception with the reason “Receiver (<PTKAjustesViewController: 0x14deba40>) has no segue with identifier ‘ayudapls’”. This message indicates that the app is trying to perform a push segue from one view controller (PTKAjustesViewController) to another, but Xcode is unable to find any segue with the specified identifier ayudapls.

Examining the Error Message

Looking closer at the error message, we notice that it mentions the receiver has no segue with the specified identifier. This suggests that there might be an issue with the way we’re defining or connecting the segues in our storyboard.

Let’s take a look at the provided code snippets:

[ self performSegueWithIdentifier:@"ayudapls" sender:self];

The performSegueWithIdentifier: method is called on the current view controller (PTKAjustesViewController) to initiate the push segue. The sender parameter is set to the current view controller, which is necessary for Xcode to determine where to navigate next.

Now, let’s examine the storyboard image:

Unfortunately, we can’t see the actual segue connection in this screenshot, but we can infer that there might be an issue with the way the segues are defined or connected.

Possible Causes

Based on the error message and the provided code snippet, here are some possible causes of the push segue not working on a device:

• Storyboard Issues: There might be an issue with the way the segues are defined or connected in the storyboard. Make sure that all segues are properly connected to their corresponding view controllers.
• Clean Build vs. Simulators: Sometimes, these weird things happen if you’re still using some old storyboard or not cleaning the previously compiled storyboard. Try renaming the storyboard and then deleting the application from your phone and reinstalling after a clean build.
• Device-Specific Issues: There might be an issue with the device itself that’s causing the push segue to fail. Try testing on different devices to see if the issue is device-specific.

Solution

Based on the provided solution, here’s what we can do to resolve the issue:

1. Rename the storyboard
2. Delete the application from your phone
3. Reinstall the application after a clean build

Here’s an example of how you can rename the storyboard in Xcode:

## Renaming the Storyboard

To rename the storyboard, follow these steps:

*   Open Xcode and select the project file.
*   In the Project Navigator, select the storyboard file (e.g., `Main.storyboard`).
*   Right-click on the storyboard file and select "Rename".
*   Enter a new name for the storyboard (e.g., `MyNewStoryboardName`) and press Enter.

Here's an example of how you can delete the application from your phone:

## Deleting the Application from Your Phone

To delete the application from your phone, follow these steps:

*   Open iTunes on your computer.
*   Select the device (e.g., iPhone or iPad) connected to your computer.
*   In the Summary tab, select "Delete App" next to the app you want to delete.
*   Confirm that you want to delete the application.

Once you've deleted the application from your phone, you can reinstall it after a clean build.

Here's an example of how you can reinstall the application:
```markdown
## Reinstalling the Application

To reinstall the application, follow these steps:

*   Open Xcode and select the project file.
*   In the Project Navigator, select the target file (e.g., `MyAppTarget`).
*   Click on the "+" button next to "Build Phases" and select "Add Build Phase".
*   Select "Product Build" as the type of build phase.
*   Click on the "+" button next to "Input Files" and select the storyboard file (e.g., `Main.storyboard`).

Once you've added the storyboard file to the target, click on the "Distribute App" button in the toolbar to reinstall the application.

### Conclusion

The push segue not found error when testing on a device but works on simulators can be a tricky issue to resolve. By examining the error message and potential causes, we can identify possible solutions to this problem. Renaming the storyboard, deleting the application from your phone, and reinstalling it after a clean build are all effective steps in resolving this issue.

However, if you're still experiencing issues after trying these solutions, don't hesitate to reach out for further assistance or explore other potential causes of the push segue not working on a device.
