How to Create a Hotspot Network in iOS App Using Swift

How to create a hotspot network in iOS app using Swift

NEHotspotHelper is an official API to do exactly this kind of stuff. Though the API is not an 'Open to All' kind. It needs the entitlement 'com.apple.developer.networking.HotspotHelper' to be included in your app. To use this entitlement you need to ask for a permission from Apple to use this class with your app's bundle identifier with a clear reason for why you need it with some other details of your app. Use this link to apply for the entitlement. Once apple sends an approval mail to you, you are good to go!

create hotspot programmatically on iOS using swift

You cannot create hotspot programmatically.

The only way to create hotspot in iOS is to go to setting and do it manually.

iOS is always conscious about the users private data and the user
settings so if you are changing any type of any settings the user
should be informed and user should on his own should turn off/on the
the settings like WiFi/hotspot or anything which is related to the
setting of the user in the settings menu.

How i share my Wifi using application swift in iOS

It isn't possible unless you jailbreak your phone. The options to create a wifi hotspot are locked to carrier settings and are only available if you jailbreak your phone.

Multipeer Connectivity With Personal Hotspot Swift

It was already asked before (to no avail): Multipeer Connectivity with personal Hotspot not working

As far as I know MPC is just an abstraction layer on top of different ways of networking. Apple uses M-DNS (Bonjour) and other techniques including Bluetooth to make networking between macOS / iOS devices as easy as possible.

Multipeer connectivity is a peer-to-peer solution and what you are describing is much more a client-server solution. That does not mean you can't pull it off but it is good to keep this in mind! This means that you want MPC as a basic level of networking and implement a client-server structure on top of that. I don't see any reason why that would not be possible when using one of the devices as a hotspot but I don't think that is even needed: Airdrop also uses MCP and it works also when devices are not in the same network.

How to programmatically connect to a WiFi network given the SSID and password

With iOS 11, Apple provided public API you can use to programmatically join a WiFi network without leaving your app.

The class you’ll need to use is called NEHotspotConfiguration.

To use it, you need to enable the Hotspot capability in your App Capabilities (Adding Capabilities). Quick working example :

NEHotspotConfiguration *configuration = [[NEHotspotConfiguration
 alloc] initWithSSID:@“SSID-Name”];
configuration.joinOnce = YES;

[[NEHotspotConfigurationManager sharedManager] applyConfiguration:configuration completionHandler:nil];

This will prompt the user to join the “SSID-Name” WiFi network. It will stay connected to the WiFi until the user leaves the app.

This doesn't work with the simulator you need to run this code with an actual device to make it work.
