IDEFoundation.IDETemplateParseError error 1.

Can you check :

- after clean Build Folder (option clean)

- if still crashes, does it crash with a new project ?

- which version of XCode ? Do you use from a framework ?

This is (most likely) one of two things:

1. You (or some utility you've used) has created or modified Xcode templates (for apps or targets) in Xcode 8 or earlier. It has never been supported to create or modify Xcode templates. Doing so risks causing errors like this.

2. You've found a bug in the Xcode 9 beta. In that case, you should submit a bug report, and stick with Xcode 8 for now.

Thank you for the answer.

The project is made in Xcode 8 and I get the error in Xcode 9 on xcdatamodeld file. If i create a new project in xcode 9 (beta 4 or 5, it is not different) there isn't problem. I'm not using some framework for Core data. I've simply created a project that use CoreData.

Because i've to insert a new feature that use ios 11 i've to installed xcode 9 beta. I've started the project on xcode 9 and it give me that error.

If it is a bug of xcode how can I submit the bug?

Thank you for answer.

I've checked and the answers are these:

1)after clean Build Folder the problem still

2)no. if I create a new project with xcode beta, there isn't problem

3)currently, xcode 9 beta 5 (bu i've had the same problem with the beta 4) i use some framework but not for CoreData. I've created in xcode 8 a project that use core data. because i'm inserting a new feature that is in ios11, I've opened the project in xcode 9 beta 4 (now updated in beta 5, but the problem persist)

To submit a bug report, you have the link "Report Bugs" at the very bottom right of thios forum page.

Unfortunally i've updated xcode 9 to beta 6 version but the problem persist. Anyone can help me? I need to update my app.
