Instead of using an ACTUAL Iphone device,Can I use an Iphone simulator instead in performing game testing which is made in Unity Iphone? There is an available simulator with Xcode and Iphone SDK upon install
Yes, you can use the XCode simulator. However, you do still need be registered as an iOS Developer with Apple.
Don’t forget to set the Target SDK to Simulator!
Not realistically, no. The simulator doesn’t tell you a thing about actual performance on the device, plus you don’t have any multitouch controls, gyroscrope, etc., so it’s fairly useless for game testing. If you don’t want an iPhone, just buy an iPod touch.
