[!] Smart quotes were detected and ignored in your Podfile. To avoid issues in the future, you should not use TextEdit for editing it. If you are not using TextEdit, you should turn off smart quotes in your editor of choice.

[!] The Podfile does not contain any dependencies.

[!] Automatically assigning platform `iOS` with version `16.2` on target `ViewControllerDemo` because no platform was specified. Please specify a platform for this target in your Podfile. See `https://guides.cocoapods.org/syntax/podfile.html#platform`.

# This is the sshd server system-wide configuration file.  See
# sshd_config(5) for more information.

# This sshd was compiled with PATH=/usr/bin:/bin:/usr/sbin:/sbin

# The strategy used for options in the default sshd_config shipped with
# OpenSSH is to specify options with their default value where
# possible, but leave them commented.  Uncommented options override the
# default value.

# This Include directive is not part of the default sshd_config shipped with
# OpenSSH. Options set in the included configuration files generally override
# those that follow.  The defaults only apply to options that have not been
# explicitly set.  Options that appear multiple times keep the first value set,
# unless they are a multivalue option such as HostKey.
