I'm trying to read the contents of a file on the filesystem in a macOS Swift app (Xcode 9 / Swift 4).

I'm using the following snippet for it:

My problem is the following:

1. This works in a Playground

If you are either trying to read/save a file or create a temporary file in a directory/folder for which you have read/write access, but receive an. Error, or something similar, your security settings may need to be updated.

When 'Save As' says you don’t have permission When using Save As, a reader keeps getting a message that they lack permission to save files. You’ve got two ways to resolve this.

3. This terminates in a permission error when I use the Cocoa App macOS app template

The permission error is the following:

I guess it's related to sandboxing but I found no information about it.

1. How can I read from the filesystem in a sandboxed app? I mean there are so many GUI apps which need an Open File dialog, it cannot be a realistic restriction of sandboxed apps to not read files from outside the sandbox.

2. Alternatively, how can I switch off sandboxing in Build Settings?

3. Finally, I tried to compare the project.pbxproj files between the default Cocoa Apps and Command Line Tool template and I didn't see any meaningful difference, like something about security or sandbox. If not here, where are those settings stored?
