where did you make your dae file? when you open the file in scenekit does it show up as scntext or as a scnnode?
i don't think you can bring text geometry from other apps as SCNText, it would be just a mesh. SCNText can only be created in scenekit.
I'm making a lot of assumptions here because i don't know where your dae came from. but the thing to do would be to replace the "label element" with scntext and then access that in your code. just a headsup scnekit text is a little hard to work with as its scale is ridiculous - 1pt = 1 meter and you can't set text at something like 0.1pts because it will be deformed. so you'll have to make your text really gigantic and scale it down. also in the editor, there are no justification options, like center-align, so if you need this text to maintaing it's relationship to your medal, it's gonna take some in-code adjustments and you'll have to account for its crazy scale.
