When I launch the application extension (widget) on the device. I have this error Application installation error

Question

This application or kit that it contains has the same package identifier as this application or another package that it contains. Package identifiers must be unique.

Answer 1

If your application package identifier is com.companyName.productName, then your extension package identifier should be com.companyName.productName.extensionName

If you assign a package ID in this way, your training profile will work for both.

Answer 2

My package ID was approved, but I had to change some settings in the provisioning profiles to fix this error.

Answer 3

The package identifier should look like this

1) Main Project ---> com.CompanyName.ProjectName

2) NotificationService (ExtensionName) ---> com.CompanyName.NotificationService

3) NotificationContent (ExtensionName) ---> com.CompanyName.NotificationContent

Answer 4

You will need to create two training profiles.

After creating the first one ending with the product name ... download and install

Then create another one similar to the first profile ending in .Extension (e.g. .Meme) ... download and install

If you create after two steps above an error may appear.

Then go to the general where you have the package identifier ... add .Extension (add it to what you have there, for example, blahblahblah.Meme)

Then you will get the "Fix problems" error message ... Click "Fix problems" and let it finish.

Then you can successfully build and install. This is how it worked for me.
