Can’t run

I love this app! It’s good, I can run every language, I can code whatever I want! There’s just one little problem, I can’t run my codes, I wish I could, it’s not a bad app, it’s pretty good actually. I just wish I could run it. I’m taking 1 star off because of that but overall good app, recommend (good app). 4 stars.

Perfekt, hier sind trotzdem Vorschläge

So gut wie alles kann ich damit machen, bis auf .plist Dateien bearbeiten. Ich brauche momentan 3 Apps: Runestones, plist Editor und irgendeinen file viewer, der order öffnen kann, die iOS nicht erlaubt zu öffnen, wie .app. Ich verstehe, dass dritteres nicht wirklich zur App passt, aber .plist als Option wäre super. Das hier soll trotzdem Lob sein, meiner Meinung nach die einzig gute text editor Option im App Store.

Crashes on Apple Vision Pro

As soon as I open it up and start to type anything on my Bluetooth keyboard, the app instantly crashes. I brought this up to the developer on X, but he completely ignored me. I guess he cares more about making other little pet projects than fixing his existing ones.
