Hey there JaredVaile,
It sounds like you are unable to join a Wi-Fi network created by your MacBook Pro with your iPhone. I would start by restarting your phone, then trying again:
Turn your iOS device off and on (restart) and reset

Press and hold the Sleep/Wake button on the top of your device until the red slider appears. Then drag the slider to turn your device completely off.
After the device turns off, press and hold the Sleep/Wake button again until you see the Apple logo.
If you still cannot connect, I would next use the following information to help troubleshoot the connection:

- Verify that you're attempting to connect to your desired Wi-Fi network.
- Make sure you're entering your Wi-Fi password correctly. Passwords may be case sensitive and may contain numbers or special characters.
- Reset network settings by tapping Settings > General > Reset > Reset Network Settings. Note: This will reset all network settings including:
- previously connected Wi-Fi networks and passwords
- recently used Bluetooth accessories
- VPN and APN settings
Thank you for using Apple Support Communities.
All the very best,
Sterling
