fix: iOS simulator

[wxh06]

Uncomment the code that opens http://127.0.0.1:${port}/#html as I am unable to open .eml file in the iOS simulator.

$ xcrun simctl openurl booted /var/folders/1t/ktc77qxs4k711pb_6cz8547w0000gn/T/e045a5cf-f88c-425c-b1d6-f9b60fa9a77c.eml
An error was encountered processing the command (domain=NSOSStatusErrorDomain, code=-50):
Simulator device returned an error for the requested operation.
Underlying error (domain=NSOSStatusErrorDomain, code=-50):
	The operation couldn’t be completed. (OSStatus error -50.)
