In my early days with iOS App development, as an individual developer for Cricbuzz app, had experienced in increasing the performance of application where we found huge spikes in memory allocations and leaks as well. To tackle this I had deep understanding how memory and performance issues can be handled/resolved using instruments tool.
Also, I applied the same learning in my recent work at Temenos, where the application had poor performance of loading data from API Service, for 300 rows of SegmentedUI widget, which is internally a UITableView. We found and resolved the performance from 19sec of loading to 3-5 seconds of overall increase in performance with smoooth scrolling as well.
