Emulate/Simulate iOS in Linux
- Run Ripple emulator(retired as of 2015-12-06) on Chrome
- Run iPadian on WineHQ
- Run QMole on Linux or Android
- Run XCode on PureDarwin
The only solution I can think of is to install VMWare or any other VT then install OSX on a VM.
It works pretty good for testing.
On linux you can check epiphany-browser, resizes the windows you'll get same bugs as in ios. Both browsers uses Webkit.
Ubuntu/Mint:
sudo apt install epiphany-browser
BrowserStack.com
On this site, you can emulate a lot of iOS's devices online.
