I have a random crash in my iOS app. This happens when on slow internet connection. My office internet speed is too fast.
For testing on simulator, I installed Network Link Conditioner as mentioned here: Installing Apple's Network Link Conditioner Tool
Now the problem is that, I selected a slower connection profile but still I'm having the normal (fast) internet speed in simulator.
I also created my own profile and set the download bandwidth to 5kbps but still no use.
I have: Mackbook retina, OSX 10.7.5, XCode: 4.4.1
Restarting Xcode and Simulator also didn't work.
Are there any additional settings required for Network Link Conditioner? Or should I do something else to regenerate the crash? Any help?
You can set the network to slow characteristic by testing on devices. Go to Settings -> Developer Settings -> Network Link Conditioner -> Enable. This is for iPhone/iPad running iOS 6 Network Link Conditioner is also available for the Mac in "Additional Tools for Xcode" for testing in the Simulator.
Note: It appears after device has been connected to Xcode, enabled for development and some app run on it.
Here's how you can test HORRIBLE network performance:
What about a development proxy server to simulate slow connections? One that looks promising is http://www.charlesproxy.com/
Can't you use a ipad/iphone connected to your mac to reproduce the crash ?
ios6 contains a network link conditioner, too: http://www.neglectedpotential.com/2012/09/ios6-network-link-conditioner/
