We have to test a native IOS mobile application for performance on apple devices, can anybody suggest me the best tools for this.
We need a tool that supports IOS native mobile application and emulates the networks - 3G, 4G, Wi-fi, LTE connections
We are looking at the tools Loadrunner 11.52, Shark, Instruments at this moment but we are not sure whether
1. LR can be used for IOS applications
2. Shark and Instruments has the ability to emulate 3G, 4G, LTE connections.

Can anybody help on this.
