第一次打开可以编译，再次打开就无法编译了。软件卸载重装后又可以编译了。希望up尽快解决此问题。否则，每用一次，就要重新下载安装一次。

### 5/5 — pretty amazing

*2020-07-28*

do realize we are playing inside limited environments. if you work in virtual environments in any way im sure youll be fine here. 

now, i am using this to learn/write/transfer to a backend. i can tell you that the code works. it works fine. ive had zero issues. 

it really depends on what you want from an application like this but for me it compiles and literally runs c programs on an ipad. i mean. think about what that signifies.
