Xcode 8 custom font doesn’t show up in interface builder

Try Below Steps: Code tested in Swift 3.

Step 1: Add Your custom font into your project( Make sure Add to Target
ticked).I am using “PermanentMarker.ttf”,”Pecita.otf” and “AROLY.ttf” font as a test font.

Note: Supporting font Type ttf and otf (Both font types should work)

Step 2: Modify the application-info.plist file.
Add the key “Fonts provided by application” in a new row and add “PermanentMarker.ttf” as new item in the Array “Fonts provided by application“.

Your plist should looks like this

Now the font will be available in Interface Builder. To use the custom font in code we need to refer to it by name, but the name often isn’t the same as the font’s filename

Now, You can access the Custom Font from your viewController. I am testing the font by placing a UIlabel to the Storyboard like below.

Update 2: Working Solution

After, imported your custom font and updated your plist.selectlabel from your storyBoard,goto Attributes Inspectorunder Label>Text type> select to Attributed and choose your custom font from the list.

Output:

Update 1

Assign font to UIToolBar:
