I'm developing an iPhone app that connects to a server. For now, the server is running locally. In the iPhone simulator, I can connect to localhost and test it that way. However, this doesn't work running it on an actual device, because then localhost is the device itself.
Is there an easy way for the device to connect to the server running on the host computer? Or do I have to resort to putting the server somewhere else?
Rather than using localhost, replace that with your computer's IP address. That should work for both the simulator and device.

I'm developing a Flutter app on a physical android device, I don't know much about networking and I'm having a trouble using an API from the phone to a local database on my laptop.
I reviewed all the answers in this post
Cannot connect to localhost API from Android app
Nothing seems to work for me, I'm using Apache server on XAMPP, and the API works just fine from the laptop (127.0.0.1:8000/api/Students) but when I try to access it from the phone it doesn't work (I replaced 127.0.0.1 with the IP of my laptop which I took from ipconfig)
XAMPP control panel
when I try to access the server from the phone using laptop-IP:80 it access normally the same with laptop-IP:80/phpmyadmin
XAMPP dashboard
but only when my phone is connected to the laptop mobile hotspot, when I connect the two devices to the same WIFI network it shows that it's unreachable:
but when I try laptop-IP:8000/api/Students this happens:
this site can't be reached
I tried to modify Apache httpd.conf:
#Listen 12.34.56.78:80
Listen 8000 <-- Added this
from what I understood this makes the server listens to port 8000 but I'm left with the same problem
NOTE: all the pictures show my attempts to use the API on my phone's Chrome browser
You need to do some tweaks to the url to access it in the device as localhost is only known to the machine not the devices on which the app is running.
The urls are different for different devices
Emulator
Real phone (with usb debugging)
1.Emulator
static const baseUrl = "http://10.0.2.2:8000";
2.Real Device
static const baseUrl = "http://localhost:8000";
Additionally you need to run these command in your cmd,
adb reverse tcp:8000 tcp:8000
Now your requests would go like:
get('$baseUrl/api/Students');
I'm trying to test my iPad app which accesses a web service currently running on my machine. How can I make it so the app can make calls to the web service?
The easiest way would be to connect your iPad and your PC to the same wireless network.
Every computer in your network has an unique Network IP (Usually something like "192.168.0.100"). If you know how to to connect to localhost it usually suffices to change the localhost to the network IP of the computer you're trying to access,
If your machine is a mac, I had a similar question which was answered here. Enable web sharing on the mac and everything should be available to you.
How is a local Debian server setup so that an iphone app in the simulator can communicate with it?
I want to send files and data to the server from an iphone app. and for now I would like it to be locally using the simulator, rather than a device using a router.
Enable NAT and you will find one network on the vm and two on the host computer, being one, a virtual network shared between the two of them. Then simply use their IP addresses as they appear in ifconfig.
I'm developing an iPhone app that has a network component. I'm developing the app in Java (Google App Engine actually), running on port 8080. And it works, when I test my app in the iPhone simulator.
But now I am trying to test on the device, and I can't hit my Jetty instance. I can certainly access my Mac via the iPhone because I'm able to hit http://10.0.1.7/~brianpapa/ and view my Home Folder when Web Sharing is turned on. But when I try to hit http://10.0.1.7:8080/, it says it can't connect to the server.
Interestingly, if I try to hit http://10.0.1.7:8080/ from my mac, it doesn't work either - I have to use localhost as the hostname instead, then it's fine. Has anybody ever encountered this before, and know how to fix it?
You need to bind the server to your external ip address. See the docs:
--address=...
The host address to use for the server. You may need to set this to be able to access the development server from another computer on your network. An address of 0.0.0.0 allows both localhost access and hostname access. Default is localhost.
I'm trying to test my iPhone application on the device.
I have a mac computer which stores my development environment.
Right now I can only access PHP files using the http://localhost/PHPFileLocation
which does not work when I try to test my app on real device.
How do I configure apache2 to be accessible from outside?
Is it possible to configure it to a specific IP address?
I want to reach some php scripts located on my development machine running apache2 from my iPhone device.
Thanks
If your computer has a WiFi card then you should be able to attach the iPhone remotely to a ad-hoc Wifi network created on your dev machine.
I'm assuming your Mac is behind a router. You should be able to configure your router to port forward connections to your WAN facing IP address to port 80 (the HTTP port) on your Mac - see http://portforward.com/ for some help.
You may also need to turn the firewall off on your Mac.
Once this is set up correctly you can hit http://yourexternalIP/PHPFileLocation in your iPhone app and this will be directed by your router to the Apache2 server on your Mac. The external IP is normally found on your router's admin page somewhere.
