In this tutorial we will look at how we can read a file line by
Xcode can often do some strange things that causes build problems etc. One of the go to methods to try and fix these issues is to delete derived data. In this tutorial, I will show you how you can delete the derived data.
Step 1: Open Preferences
The first thing we need to do is to open preferences, there are two ways to do this. The first way is to click on
Xcode in the top left of the menu bar and then to click on
If you want to use a shortcut to open preferences, you can do this

Derived Data folder highlighted:
Step 3: Close Xcode
This is a super quick step, we need to quit

Once I have deleted the
DerivedData folder I make sure to delete it from the trash as well. Normally I completely empty my trash folder, but you can just delete the
After removing the folder from trash you can start
Xcode again. When you build the app it will recreate either the
Deleting derived data can be annoying, it also seems to be something that depends on the project. I have been working on multiple projects and it seems that the smaller projects don't really have these issues as often as the larger projects.
