If you had just followed the setup guide in the docs you may see something like this:

sample % ns run ios
Searching for devices...

Common solution: Open a new terminal window - and retry.

EMFILE: too many open files 'FILE_PATH'

Webpack compilation complete. Watching for file changes.
Watchpack Error (watcher): Error: EMFILE: too many open files 'FILE_PATH'
Watchpack Error (watcher): Error: EMFILE: too many open files 'FILE_PATH'
Watchpack Error (watcher): Error: EMFILE: too many open files 'FILE_PATH' <-- This repeats many times

Solution:

Try adding this to your ~/.bash_profile if you have one or ~/.zshenv if using Zsh:

export NODE_OPTIONS="--max-old-space-size=6096"

Then open a new terminal window and run your app.

ERROR: ../../node_modules/@nativescript/core/ui/proxy-view-container/index.d.ts:10:9 - error TS2611: 'ios' is defined as a property in class 'LayoutBase', but is overridden here in 'ProxyViewContainer' as an accessor.

11     get android(): any;

Common solution: If run into this, you can add this to your tsconfig.json:

"skipDefaultLibCheck": true,
"skipLibCheck": true,
