My project have ejected with expo kit and I am following instruction of the eject screen. It was working fine before ejection but now I cannot let my code run.
I build my codes in Xcode and it was successfully. I can run simulator but I can see nothing from it, just white screen. Expect I have a red banner on the bottom with those "dismiss""reload""copy""more info". I try to copy but nothing goes to my clipboard.
the repo of my ejection is:
1. npm run eject
2. choose expoKit
3. waiting for it to eject
4. updated expo sdk to 26
5. change react native to expo fork
6. pod install
did I miss something?
