So I followed this video to build a simple Shopping List app using React Native: [this video] It runs fine when I use react-native run-ios to get it running on the iOS simulator(actually some problems too, but I'm working on it), but when I try to run it using react-native run-android , a lot of problems arise. 1st problem, when the app does come up, I try to add an item, but after I press the "Add Item" button, this Type Error: u.slice is not a function. shows up. [LINK] so, as the problem code comes from index.android.bundle, I go there, and I have absolutely no idea what I am looking at and what I should do about it to fix the problem. In case it helps, this is the 157th line of code where the

Cites Jon · 2021-07 · Stack Overflow · on “React Native App in iOS emulator forever stuck building”
I've been following this intro course about React Native [this video] and when I get to the point to run the build it just gets stuck in "Building the app...." and never finishes. I don't even get any error codes after running the command => react-native run-ios It just gets stuck forever building with a large majority of my CPU being used. The Xcode workspace is found, the iPhone emulator is launched and I can see the default screen, but the application just never finishes building. Any insight on what could be causing this would be great—I haven't found anyone else with this specific problem. Operating System: macOS Big Sur Version 11.4
